Automotive ProASIC3 Flash Family FPGAs
Introduction and Overview
Security
General Description
The nonvolatile, flash-based Automotive ProASIC3
devices do not require a boot PROM, so there is no
vulnerable external bitstream that can be easily copied.
Automotive ProASIC3 devices incorporate FlashLock,
Automotive ProASIC3 nonvolatile flash technology gives
automotive system designers the advantage of a secure,
low-power, single-chip solution that is live at power-up
(LAPU). Automotive ProASIC3 is reprogrammable and
offers time-to-market benefits at an ASIC-level unit cost.
These features enable designers to create high-density
systems using existing ASIC or FPGA design flows and
tools.
which
provides
a
unique
combination
of
reprogrammability and design security without external
overhead, advantages that only an FPGA with
nonvolatile flash programming can offer.
Automotive ProASIC3 devices utilize a 128-bit flash-
Automotive ProASIC3 devices offer 1 kbit of on-chip,
reprogrammable, nonvolatile FlashROM storage as well
as clock conditioning circuitry based on an integrated
phase-locked loop (PLL). Automotive ProASIC3 devices
have up to 1 million system gates, supported with up to
144 kbits of SRAM and up to 300 user I/Os.
based lock and
a
separate AES key to secure
programmed intellectual property and configuration
data. In addition, all FlashROM data in Automotive
ProASIC3 devices can be encrypted prior to loading,
using the industry-leading AES-128 (FIPS192) bit block
cipher encryption standard. The AES was adopted by the
National Institute of Standards and Technology (NIST) in
2000 and replaces the 1977 DES standard. Automotive
ProASIC3 devices have a built-in AES decryption engine
and a flash-based AES key that make them the most
comprehensive programmable logic device security
solution available today. Automotive ProASIC3 devices
with AES-based security allow for secure, remote field
updates over public networks such as the Internet, and
ensure that valuable IP remains out of the hands of
system overbuilders, system cloners, and IP thieves. The
contents of a programmed Automotive ProASIC3 device
cannot be read back, although secure design verification
is possible. Additionally, security features of Automotive
ProASIC3 devices provide anti-tampering protection.
Automotive ProASIC3 devices are the only firm-error-
immune automotive grade FPGAs. Firm-error immunity
makes them ideally suited for demanding applications in
powertrain, safety, and telematics-based subsystems,
where firm-error failure is not an option.
Firm errors in SRAM-based FPGAs can result in high
defect levels in field-deployed systems. These
unavoidable defects must be considered separately from
standard defects and failure mechanisms when looking
at overall system quality and reliability.
Flash Advantages
Reduced Cost of Ownership
Security, built into the FPGA fabric, is an inherent
component of the Automotive ProASIC3 family. The flash
cells are located beneath seven metal layers, and many
device design and layout techniques have been used to
make invasive attacks extremely difficult. The
Automotive ProASIC3 family, with FlashLock and AES
security, is unique in being highly resistant to both
invasive and noninvasive attacks. Your valuable IP is
protected and secure. An Automotive ProASIC3 device
Advantages to the designer extend beyond low unit cost,
performance, and ease of use. Unlike SRAM-based
FPGAs, flash-based Automotive ProASIC3 devices allow
all functionality to be live at power-up; no external boot
PROM is required. On-board security mechanisms
prevent access to all the programming information and
enable secure remote updates of the FPGA logic. Flash-
based FPGAs are LAPU Class 0 devices, offering the
lowest available power in a single-chip device and
providing firm-error immunity. The Automotive ProASIC3
family device architecture mitigates the need for ASIC
migration at high user volumes. This makes the

programmable logic designs.
Single Chip
Automotive ProASIC3 family
a
cost-effective ASIC
Flash-based FPGAs store their configuration information
in on-chip flash cells. Once programmed, the
configuration data is an inherent part of the FPGA
structure, and no external configuration data needs to
be loaded at system power-up (unlike SRAM-based
FPGAs). Therefore, flash-based Automotive ProASIC3
replacement solution, especially for automotive
applications.
v2.0
1-1
Automotive ProASIC3 Flash Family FPGAs
FPGAs do not require system configuration components
such as EEPROMs or microcontrollers to load device
configuration data. This reduces bill-of-materials costs
and PCB area, and increases security and system
reliability.
applications. Automotive ProASIC3 devices have only a
very limited power-on current surge and no high-current
transition period, both of which occur on many FPGAs.
Automotive ProASIC3 devices also have low dynamic
power consumption to further maximize power savings.
Live at Power-Up
Advanced Flash Technology
The Actel flash-based Automotive ProASIC3 devices
support Level 0 of the LAPU classification standard. This
feature helps in system component initialization,
execution of critical tasks before the processor wakes up,
setup and configuration of memory blocks, clock
generation, and bus activity management. The LAPU
feature of flash-based Automotive ProASIC3 devices
greatly simplifies total system design and reduces total
system cost, often eliminating the need for CPLDs and
external clock generation PLLs. In addition, glitches and
brownouts in system power will not corrupt the
Automotive ProASIC3 device's flash configuration, and
unlike SRAM-based FPGAs, the device will not have to be
reloaded when system power is restored. This enables
the reduction or complete removal of the configuration
PROM, expensive voltage monitor, brownout detection,
and clock generator devices from the PCB design. Flash-
based Automotive ProASIC3 devices simplify total system
design and reduce cost and design risk while increasing
system reliability and improving system initialization
time.
The Automotive ProASIC3 family offers many benefits,
including nonvolatility and reprogrammability, through
an advanced flash-based, 130-nm LVCMOS process with
seven layers of metal. Standard CMOS design techniques
are used to implement logic and control functions. The
combination of fine granularity, enhanced flexible
routing resources, and abundant flash switches allows
for very high logic utilization without compromising
device routability or performance. Logic functions within
the device are interconnected through a four-level
routing hierarchy.
Advanced Architecture
The proprietary Automotive ProASIC3 architecture
provides granularity comparable to standard-cell ASICs.
The Automotive ProASIC3 device consists of five distinct
and programmable architectural features (Figure 1-1 and
Figure 1-2 on page 1-3):

Dedicated FlashROM

Extensive CCCs and PLLs
Advanced I/O structure
Firm-Error Immune
Firm errors occur most commonly when high-energy
neutrons, generated in the upper atmosphere, strike a
configuration cell of an SRAM FPGA. The energy of the
collision can change the state of the configuration cell
and thus change the logic, routing, or I/O behavior in an
unpredictable way. These errors are impossible to
prevent in SRAM FPGAs. The consequence of this type of
error can be a complete system failure. Firm errors do
not exist in the configuration memory of Automotive
ProASIC3 flash-based FPGAs. Once it is programmed, the
flash cell configuration element of Automotive ProASIC3
FPGAs cannot be altered by high-energy neutrons and is
therefore immune to them. Recoverable (or soft) errors
occur in the user data SRAM of all FPGA devices. These
can easily be mitigated by using error detection and
correction (EDAC) circuitry built into the FPGA fabric.
The FPGA core consists of a sea of VersaTiles. Each
VersaTile can be configured as a three-input logic
function, a D-flip-flop (with or without enable), or a
latch by programming the appropriate flash switch
interconnections. The versatility of the Automotive
ProASIC3 core tile as either a three-input lookup table
(LUT) equivalent or a D-flip-flop/latch with enable allows
for efficient use of the FPGA fabric. The VersaTile
capability is unique to the Actel ProASIC family of third-
generation-architecture flash FPGAs. VersaTiles are
connected with any of the four levels of routing
hierarchy. Flash switches are distributed throughout the
device
to
provide
nonvolatile,
reconfigurable
interconnect programming. Maximum core utilization is
possible for virtually any design.
In addition, extensive on-chip programming circuitry
allows for rapid, single-voltage (3.3 V) programming of
Automotive ProASIC3 devices via an IEEE 1532 JTAG
interface.
Low Power
Flash-based Automotive ProASIC3 devices exhibit very
low power characteristics, similar to those of an ASIC,
making them an ideal choice for power-sensitive

User Nonvolatile FlashROM
Actel Automotive ProASIC3 devices have 1 kbit of on-
chip, user-accessible, nonvolatile FlashROM. The
FlashROM can be used in diverse system applications:
The Actel Automotive ProASIC3 development software
solutions, Libero® Integrated Design Environment (IDE)
and Designer, have extensive support for the FlashROM.
One such feature is auto-generation of sequential
programming files for applications requiring a unique
serial number in each part. Another feature allows the
inclusion of static data for system version control. Data
for the FlashROM can be generated quickly and easily
using Actel Libero IDE and Designer software tools.
Comprehensive programming file support is also
included to allow for easy programming of large
numbers of parts with differing FlashROM contents.

Version management
The FlashROM is written using the standard Automotive
ProASIC3 IEEE 1532 JTAG programming interface.
Automotive ProASIC3 devices have embedded SRAM
blocks along their north and south sides. Each variable-
aspect-ratio SRAM block is 4,608 bits in size. Available
memory configurations are 256×18, 512×9, 1k×4, 2k×2,
and 4k×1 bits. The individual blocks have independent
read and write ports that can be configured with
different bit widths on each port. For example, data can
be sent through a 4-bit port and read as a single
bitstream. The embedded SRAM blocks can be initialized
via the device JTAG port (ROM emulation mode) using
the UJTAG macro. For more information, refer to the
application note, UJTAG Applications in ProASIC3/E
Devices.
The FlashROM can be programmed via the JTAG
programming interface, and its contents can be read
back either through the JTAG programming interface or
via direct FPGA core addressing. Note that the FlashROM
can only be programmed from the JTAG interface and
cannot be programmed from the internal logic array.
The FlashROM is programmed as 8 banks of 128 bits;
however, reading is performed on a byte-by-byte basis
using a synchronous interface. A 7-bit address from the
FPGA core defines which of the 8 banks and which of the
16 bytes within that bank are being read. The three most
significant bits (MSBs) of the FlashROM address

Exceptional tolerance to input period jitter—
allowable input jitter is up to 1.5 ns (for PLL only)
PLL and CCC
Automotive ProASIC3 devices provide designers with
very flexible clock conditioning circuit (CCC) capabilities.
Each member of the Automotive ProASIC3 family
contains six CCCs. One CCC (center west side) has a PLL.
Four precise phases; maximum misalignment
between adjacent phases of 40 ps × 350 MHz /
fOUT_CCC (for PLL only)
The six CCC blocks are located at the four corners and the
centers of the east and west sides. One CCC (center west
side) has a PLL.
Global Clocking
Automotive ProASIC3 devices have extensive support for
multiple clocking domains. In addition to the CCC and
PLL support described above, there is a comprehensive
global clock distribution network.
All six CCC blocks are usable; the four corner CCCs and
the east CCC allow simple clock delay operations as well
as clock spine access (refer to the "Clock Conditioning
Circuits" section on page 2-13 for more information).
Each VersaTile input and output port has access to nine
VersaNets: six chip (main) and three quadrant global
networks. The VersaNets can be driven by the CCC or
directly accessed from the core via multiplexers (MUXes).
The VersaNets can be used to distribute low-skew clock
signals or for rapid distribution of high-fanout nets.
The inputs of the six CCC blocks are accessible from the
FPGA core or from one of several inputs located near the
CCC that have dedicated connections to the CCC block.
The CCC block has these key features:

stores the programming information (Figure 2-1). One is
the sensing transistor, which is only used for writing and
verification of the floating gate voltage. The other is the
switching transistor. The latter is used to connect or
separate routing nets, or to configure VersaTile logic. It is
also used to erase the floating gate. Dedicated high-
performance lines are connected as required using the
flash switch for fast, low-skew, global signal distribution
throughout the device core. Maximum core utilization is
possible for virtually any design. The use of the flash
switch technology also removes the possibility of firm
errors.
Introduction
Flash Technology
Advanced Flash Switch
Unlike SRAM FPGAs, the Automotive ProASIC3 family
uses
a
live-at-power-up ISP flash switch as its
programming element. Flash cells are distributed
throughout the device to provide nonvolatile,
reconfigurable programming to connect signal lines to
the appropriate VersaTile inputs and outputs. In the flash
switch, two transistors share the floating gate, which

Device Overview
The Automotive ProASIC3 device family consists of
distinct programmable architectural features (Figure 2-2
and Figure 2-3 on page 2-3):
Enable D-flip-flop with clear or set (on a fourth
input)
VersaTiles can flexibly map the logic and sequential gates
of a design. The inputs of the VersaTile can be inverted
(allowing bubble pushing), and the output of the tile can
connect to high-speed, very-long-line routing resources.
VersaTiles and larger functions can be connected with
any of the four levels of routing hierarchy.

Dedicated SRAM memory
When the VersaTile is used as an enable D-flip-flop,
SET/CLR is supported by a fourth input. The SET/CLR
signal can only be routed to this fourth input over the
VersaNet (global) network. However, if, in the user’s
design, the SET/CLR signal is not routed over the
VersaNet network, a compile warning message will be
given, and the intended logic function will be
implemented by two VersaTiles instead of one.
Core Architecture
VersaTile
The proprietary Automotive ProASIC3 family architecture
provides granularity comparable to gate arrays. The
Automotive ProASIC3 device core consists of a sea-of-
VersaTiles architecture.
The output of the VersaTile is F2 (Figure 2-4 on page 2-4)
when the connection is to the ultra-fast local lines, or YL
when the connection is to the efficient long-line or very-
long-line resources.
As illustrated in Figure 2-4 on page 2-4, there are four
inputs in a logic VersaTile cell, and each VersaTile can be
configured using the appropriate flash switch

Array Coordinates
During many place-and-route operations in the Actel
Designer software tool, it is possible to set constraints
that require array coordinates. Table 2-1 provides array
coordinates of core cells and memory blocks. The array
coordinates are measured from the lower left (0, 0). They
can be used in region constraints for specific logic
groups/blocks, designated by a wildcard, and can contain
core cells, memories, and I/Os.
not listed in Table 2-1. The Designer ChipPlanner tool
provides the array coordinates of all I/O locations. I/O
and cell coordinates are used for placement constraints.
However, I/O placement is easier by package pin
assignment.
Figure 2-5 illustrates the array coordinates of an A3P1000
device. For more information on how to use array
coordinates for region/placement constraints, see the
Designer User's Guide or online help (available in the
software) for Automotive ProASIC3 software tools.
I/O and cell coordinates are used for placement
constraints. Two coordinate systems are needed because
there is not a one-to-one correspondence between I/O
cells and core cells. In addition, the I/O coordinate system
changes depending on the die/package combination. It is

Routing Architecture
Routing Resources
The routing structure of Automotive ProASIC3 devices is
designed to provide high performance through a flexible
four-level hierarchy of routing resources: ultra-fast local
resources; efficient long-line resources; high-speed, very-
long-line resources; and the high-performance VersaNet
networks.
The high-speed, very-long-line resources, which span the
entire device with minimal delay, are used to route very
long or high-fanout nets: length +/–12 VersaTiles in the
vertical direction and length +/–16 in the horizontal
direction from a given core VersaTile (Figure 2-8 on page
2-8). Very long lines in Automotive ProASIC3 devices
have been enhanced over those in previous ProASIC
families. This provides a significant performance boost
for long-reach signals.
The ultra-fast local resources are dedicated lines that allow
the output of each VersaTile to connect directly to every
input of the eight surrounding VersaTiles (Figure 2-6). The
exception to this is that the SET/CLR input of a VersaTile
configured as a D-flip-flop is driven only by the VersaTile
global network.
The high-performance VersaNet global networks are
low-skew, high-fanout nets that are accessible from
external pins or internal logic (Figure 2-9 on page 2-9).
These nets are typically used to distribute clocks, resets,
and other high-fanout nets requiring minimum skew.
The VersaNet networks are implemented as clock trees,
and signals can be introduced at any junction. These can
be employed hierarchically, with signals accessing every
input on all VersaTiles.
The efficient long-line resources provide routing for longer
distances and higher-fanout connections. These resources
vary in length (spanning one, two, or four VersaTiles), run
both vertically and horizontally, and cover the entire
Automotive ProASIC3 device (Figure 2-7 on page 2-7).
Each VersaTile can drive signals onto the efficient long-line
resources, which can access every input of every VersaTile.
Routing software automatically inserts active buffers to
limit loading effects.

quadrants. Each core VersaTile has access to nine global
network resources: three quadrant and six chip-wide (main)
global networks, and a total of 18 globals on the device.
Each of these networks contains spines and ribs that reach
all the VersaTiles in the quadrants (Figure 2-10 on page 2-
10). This flexible VersaNet global network architecture
allows users to map up to 144 different internal/external
clocks in an Automotive ProASIC3 device. Details on the
VersaNet networks are given in Table 2-2 on page 2-10.
The flexible use of the Automotive ProASIC3 VersaNet
global network allows the designer to address several
design requirements. User applications that are clock-
resource-intensive can easily route external or gated
internal clocks using VersaNet global routing networks.
Designers can also drastically reduce delay penalties and
minimize resource usage by mapping critical, high-fanout
nets to the VersaNet global network.
Clock Resources (VersaNets)
Automotive ProASIC3 devices offer powerful and flexible
control of circuit timing through the use of analog
circuitry. Each chip has up to six CCCs. The west CCC also
contains a phase-locked loop (PLL) core, delay lines, a
phase shifter (0°, 90°, 180°, 270°), and clock
multipliers/dividers. Each CCC has all the circuitry needed
for the selection and interconnection of inputs to the
VersaNet global network. The east and west CCCs each
have access to three VersaNet global lines on each side of
the chip (six total lines).
Advantages of the VersaNet Approach
One of the architectural benefits of Automotive ProASIC3
is the set of powerful and low-delay VersaNet global
networks. Automotive ProASIC3 offers six chip (main)
global networks that are distributed from the center of the
FPGA array (Figure 2-9). In addition, Automotive ProASIC3
devices have three regional globals in each of the four chip

usage of these low-skew networks can result in
significant improvement in design performance on
Automotive ProASIC3 devices.
VersaNet Global Networks and Spine Access
The ProASIC3 architecture contains
a total of 18
segmented global networks that can access the
VersaTiles, SRAM, and I/O tiles of the Automotive
ProASIC3 device. There are nine global network
resources in each device quadrant: three quadrant
globals and six chip (main) global networks. Each device
has a total of 18 globals. These VersaNet global networks
offer fast, low-skew routing resources for high-fanout
nets, including clock signals. In addition, these highly
segmented global networks offer users the flexibility to
create low-skew local networks using spines for up to
144 internal/external clocks (in an A3P1000 device) or
The nine spines available in a vertical column reside in
global networks with two separate regions of scope: the
quadrant global network, which has three spines, and
the chip (main) global network, which has six spines.
Note that there are three quadrant spines in each
quadrant of the device. There are four quadrant global
network regions per device (Figure 2-10).
The spines are the vertical branches of the global
network tree, shown in Figure 2-11 on page 2-11. Each

high-fanout inputs to a design.
Details of the chip (main) global network spine-selection
MUX are presented in Figure 2-12 on page 2-12. The
spine drivers for each spine are located in the middle of
the die.
Each spine and its associated ribs cover a certain area of
the Automotive ProASIC3 device (the "scope" of the
spine; see Figure 2-9 on page 2-9). Each spine is accessed
by the dedicated global network MUX tree architecture,
which defines how a particular spine is driven—either by
the signal on the global network from a CCC, for
example, or by another net defined by the user (Figure 2-
12 on page 2-12). Quadrant spines can be driven from
user I/Os on the north and south sides of the die. The
ability to drive spines in the quadrant global networks
Quadrant spines are driven from a north or south rib.
Access to the top and bottom ribs is from the corner CCC
or from the I/Os on the north and south sides of the
device.

Clock Aggregation
Clock aggregation allows for multi-spine clock domains.
A MUX tree provides the necessary flexibility to allow
long lines or I/Os to access domains of one, two, or four
global spines. Signal access to the clock aggregation
system is achieved through long-line resources in the
central rib, and also through local resources in the north
and south ribs, allowing I/Os to feed directly into the
clock system. As Figure 2-13 indicates, this access system
is contiguous.
There is no break in the middle of the chip for the north
and south I/O VersaNet access. This is different from the
quadrant clocks located in these ribs, which only reach
the middle of the rib. Refer to the Using Global
Resources in Actel ProASIC3/E Devices application note.

Clock Conditioning Circuits
Overview of Clock Conditioning Circuitry
In Automotive ProASIC3 devices, the CCCs are used to
implement frequency division, frequency multiplication,
phase shifting, and delay operations.
Global Buffers with No Programmable Delays
The CLKBUF and CLKBUF_LVPECL/LVDS/BLVDS/M-LVDS
macros are composite macros that include an I/O macro
driving
a global buffer, which uses a hardwired
connection.
The CCCs are available in six chip locations—each of the
four chip corners and the middle of the east and west
chip sides.
The CLKBUF, CLKBUF_LVPECL/LVDS/BLVDS/M-LVDS, and
CLKINT macros are pass-through clock sources and do
not use the PLL or provide any programmable delay
functionality.
Each CCC can implement up to three independent global
buffers (with or without programmable delay) or a PLL
function (programmable frequency division/multiplication,
phase shift, and delays) with up to three global outputs.
Unused global outputs of a PLL can be used to
The CLKINT macro provides a global buffer function
driven by the FPGA core.
Many specific CLKBUF macros support the wide variety of
single-ended and differential I/O standards supported by
Automotive ProASIC3 devices. The available CLKBUF
macros are described in the Fusion, IGLOO/e and
ProASIC3/E Macro Library Guide.
implement independent global buffers, up to
maximum of three global outputs for a given CCC.
a
A global buffer can be placed in any of the three global
locations (CLKA-GLA, CLKB-GLB, or CLKC-GLC) of a given
CCC.
Global Buffer with Programmable Delay
A PLL macro uses the CLKA CCC input to drive its reference
clock. It uses the GLA and, optionally, the GLB and GLC
global outputs to drive the global networks. A PLL macro
can also drive the YB and YC regular core outputs. The GLB
(or GLC) global output cannot be reused if the YB (or YC)
output is used (Figure 2-14 on page 2-14). Refer to the
"PLL Macro" section on page 2-15 for more information.
The CLKDLY macro is a pass-through clock source that
does not use the PLL, but provides the ability to delay the
clock input using a programmable delay. The CLKDLY
macro takes the selected clock input and adds a user-
defined delay element. This macro generates an output
clock phase shift from the input clock.
The CLKDLY macro can be driven by an INBUF* macro to
create a composite macro, where the I/O macro drives
the global buffer (with programmable delay) using a
hardwired connection. In this case, the I/O must be
placed in one of the dedicated global I/O locations.
Each global buffer, as well as the PLL reference clock, can
be driven from one of the following:
•
•
•
3 dedicated single-ended I/Os using a hardwired
connection
Many specific INBUF macros support the wide variety of
single-ended and differential I/O standards supported by
the Automotive ProASIC3 family. The available INBUF
macros are described in the Fusion, IGLOO/e and
ProASIC3/E Macro Library Guide.
2 dedicated differential I/Os using a hardwired
connection
The FPGA core
The CCC block is fully configurable, either via flash
configuration bits set in the programming bitstream or
through an asynchronous interface. This asynchronous
interface is dynamically accessible from inside the
Automotive ProASIC3 device to permit parameter
changes (such as divide ratios) during device operation.
To increase the versatility and flexibility of the clock
conditioning system, the CCC configuration is
determined either by the user during the design process,
with configuration data being stored in flash memory as
part of the device programming procedure, or by writing
data into a dedicated shift register during normal device
operation. This latter mode allows the user to
dynamically reconfigure the CCC without the need for
core programming. The shift register is accessed through
a simple serial interface. Refer to the UJTAG Applications
in ProASIC3/E Devices application note and the "CCC
The CLKDLY macro can be driven directly from the FPGA
core.
The CLKDLY macro can also be driven from an I/O that is
routed through the FPGA regular routing fabric. In this
case, users must instantiate a special macro, PLLINT, to
differentiate from the hardwired I/O connection
described earlier.
The visual CLKDLY configuration in the SmartGen part of
the Libero IDE and Designer tools allows the user to
select the desired amount of delay and configures the
delay elements appropriately. SmartGen also allows the
user to select the input clock source. SmartGen will
automatically instantiate the special macro, PLLINT,
when needed.

1. Visit the Actel website for future application notes concerning dynamic PLL reconfiguration. The PLL is only supported on the west
center CCC. Refer to the "PLL Macro" section on page 2-15 for signal descriptions.
2. Refer to the Fusion, IGLOO/e and ProASIC3/E Macro Library Guide for more information.
3. Many standard-specific INBUF macros (for example, INBUF_LVDS) support the wide variety of single-ended and differential I/O
standards supported by the Automotive ProASIC3 family. The available INBUF macros are described in the Fusion, IGLOO/e and
ProASIC3/E Macro Library Guide.

There are five delay elements to support phase control
on all five outputs (GLA, GLB, GLC, YB, and YC).
PLL Macro
The PLL functionality of the clock conditioning block is
supported by the PLL macro. Note that the PLL macro
reference clock uses the CLKA input of the CCC block,
which is only accessible from the global A[0:2] package
pins. Refer to Figure 2-15 on page 2-17 for more
information.
There is also a delay element in the feedback loop that
can be used to advance the clock relative to the
reference clock.
The PLL macro reference clock can be driven by an INBUF*
macro to create a composite macro, where the I/O macro
drives the global buffer (with programmable delay) using a
hardwired connection. In this case, the I/O must be placed
in one of the dedicated global I/O locations.
The PLL macro provides five derived clocks (three
independent) from a single reference clock. The PLL
macro also provides power-down input and lock output
signals. See Figure 2-17 on page 2-16 for more
information.
The PLL macro reference clock can be driven directly
from the FPGA core.
Inputs:
The PLL macro reference clock can also be driven from an
I/O that is routed through the FPGA regular routing
fabric. In this case, users must instantiate a special macro,
PLLINT, to differentiate from the hardwired I/O
connection described earlier.
•
•
CLKA: selected clock input
POWERDOWN (active low): disables PLLs. The
default state is Powerdown On (active low).
Outputs:
During power-up, the PLL outputs will toggle around the
maximum frequency of the voltage-controlled oscillator
(VCO) gear selected. Toggle frequencies can range from
40 MHz to 250 MHz. This will continue as long as the
clock input (CLKA) is constant (HIGH or LOW). This can be
prevented by LOW assertion of the POWERDOWN signal.
•
•
•
LOCK: indicates that PLL output has locked on the
input reference signal
GLA, GLB, GLC: outputs to respective global
networks
YB, YC: allows output from the CCC to be routed
back to the FPGA core
The visual PLL configuration in SmartGen, part of the
Libero IDE and Designer tools, will derive the necessary
internal divider ratios based on the input frequency and
desired output frequencies selected by the user.
SmartGen also allows the user to select the various delays
and phase shift values necessary to adjust the phases
between the reference clock (CLKA) and the derived
clocks (GLA, GLB, GLC, YB, and YC). SmartGen also allows
the user to select the input clock source. SmartGen
automatically instantiates the special macro, PLLINT,
when needed.
As previously described, the PLL allows up to five flexible
and independently configurable clock outputs. Figure 2-20
on page 2-19 illustrates the various clock output options
and delay elements.
As illustrated, the PLL supports three distinct output
frequencies from a given input clock. Two of these (GLB
and GLC) can be routed to the B and C global network
access, respectively, and/or routed to the device core (YB
and YC).

CCC Physical Implementation
CCC Programming
The CCC is composed of the following (Figure 2-20):
The CCC block is fully configurable, either via static flash
configuration bits in the array, set by the user in the
programming bitstream, or through an asynchronous
dedicated shift register dynamically accessible from
inside the Automotive ProASIC3 device. The dedicated
shift register permits changes in parameters, such as PLL
divide ratios and delays, during device operation. This
latter mode allows the user to dynamically reconfigure
the PLL without the need for core programming. The
register file is accessed through a simple serial interface.

Nonvolatile Memory (NVM)
Overview of User Nonvolatile FlashROM
Automotive ProASIC3 devices have 1 kbit of on-chip
nonvolatile flash memory that can be read from the
FPGA core fabric. The FlashROM is arranged in 8 banks of
128 bits during programming. The 128 bits in each bank
are addressable as 16 bytes during the read-back of the
FlashROM from the FPGA core (Figure 2-21).
bank erase prior to reprogramming the bank. The
FlashROM supports synchronous read. The address is
latched on the rising edge of the clock, and the new
output data is stable after the falling edge of the same
clock cycle. Refer to Table 3-44 on page 3-96 for the
timing diagram. The FlashROM can be read on byte
boundaries. The upper three bits of the FlashROM
address from the FPGA core define the bank being
accessed. The lower four bits of the FlashROM address
from the FPGA core define which of the 16 bytes in the
bank is being accessed.
The FlashROM can only be programmed via the IEEE
1532 JTAG port. It cannot be programmed directly from
the FPGA core. When programming, each of the eight
128-bit banks can be selectively reprogrammed. The
FlashROM can only be reprogrammed on a bank
boundary. Programming involves an automatic, on-chip

SRAM and FIFO
Automotive ProASIC3 devices (A3P250 and A3P1000)
have embedded SRAM blocks along their north and
south sides; A3P060 and A3P125 devices have embedded
SRAM blocks on the north side only. To meet the needs
of high-performance designs, the memory blocks
operate strictly in synchronous mode for both read and
write operations. The read and write clocks are
completely independent, and each may operate at any
desired frequency up to 250 MHz.
diagrams of the memory modules are illustrated in
Figure 2-22 on page 2-22.
Simultaneous dual-port read/write and write/write
operations at the same address are allowed when certain
timing requirements are met.
During RAM operation, addresses are sourced by the
user logic and the FIFO controller is ignored. In FIFO
mode, the internal addresses are generated by the FIFO
controller and routed to the RAM array by internal
MUXes. Refer to Figure 2-23 on page 2-23 for more
information about the implementation of the embedded
FIFO controller.

512×9, 256×18 (2-port RAM—1 read and 1 write)
Sync write, sync pipelined / nonpipelined read
The Automotive ProASIC3 architecture enables the read
and write sizes of RAMs to be organized independently,
allowing for bus conversion. For example, the write side
size can be set to 256×18 and the read size to 512×9.
ProASIC3 Automotive devices support single-port SRAM
capabilities or dual-port SRAM only under specific
conditions. Dual-port mode is supported if the clocks to
the two SRAM ports are the same and 180° out of phase
(i.e., the port A clock is the inverse of the port B clock).
Both the write width and read width for the RAM blocks
can be specified independently with the WW (write
width) and RW (read width) pins. The different D×W
configurations are 256×18, 512×9, 1k×4, 2k×2, and 4k×1.
The Actel Libero IDE software macro libraries support a
dual-port macro only.
Refer to the allowable RW and WW values supported for
each of the RAM macro types in Table 2-7 on page 2-25.
For use of this macro as a single-port SRAM, the inputs
and clock of one port should be tied off (grounded) to
prevent errors during design compile.
When widths of one, two, or four are selected, the ninth
bit is unused. For example, when writing nine-bit values
and reading four-bit values, only the first four bits and
the second four bits of each nine-bit value are
addressable for read operations. The ninth bit is not
accessible.
For use in dual-port mode, the same clock with an
inversion between the two clock pins of the macro
should be used in design to prevent errors during
compile.
The ProASIC3 memory block includes dedicated FIFO
control logic to generate internal addresses and external
flag logic (FULL, EMPTY, AFULL, AEMPTY). Block
Conversely, when writing four-bit values and reading
nine-bit values, the ninth bit of a read operation will be
undefined. The RAM blocks employ little-endian byte
order for read and write operations.

RA and REN valid. The read address is registered
on the read port clock active edge, and data
appears at RD after the RAM access time. Setting
PIPE to OFF enables this mode.
WEN and REN
Read and write enables. WEN is active low and REN is
active high by default. These signals can be configured as
active high or low.
WCLK and RCLK
•
Read Pipelined (synchronous—2 clock edges): The
pipelined mode incurs an additional clock delay
from address to data but enables operation at a
much higher frequency. The read address is
registered on the read port active clock edge, and
the read data is registered and appears at RD after
the second read clock edge. Setting PIPE to ON
enables this mode.
These are the clock signals for the synchronous read and
write operations. For FIFO4K18, the same clock 180° out
of phase (inverted) between clock pins should be used.
RPIPE
This signal is used to specify pipelined read on the
output. A LOW on RPIPE indicates a nonpipelined read,
and the data appears on the output in the same clock
cycle. A HIGH indicates a pipelined read, and data
appears on the output in the next clock cycle.
•
Write (synchronous—1 clock edge): On the write
clock active edge, the write data is written into
the SRAM at the write address when WEN is HIGH.
The setup times of the write address, write
enables, and write data are minimal with respect
to the write clock. Write and read transfers are
described with timing requirements in the "DDR
Module Specifications" section on page 3-64.
RESET
This active low signal resets the control logic and forces
the output hold state registers to zero when asserted. It
does not reset the contents of the memory array
(Table 2-9 on page 2-27).
While the RESET signal is active, read and write
operations are disabled. As with any asynchronous RESET
signal, care must be taken not to assert it too close to the
edges of active read and write clocks. Refer to the tables
beginning with Table 3-120 on page 3-94 for the
specifications.
RAM Initialization
Each SRAM block can be individually initialized on power-
up by means of the JTAG port using the UJTAG mechanism
(refer to the "JTAG 1532" section on page 2-51 and the
ProASIC3/E SRAM/FIFO Blocks application note). The shift

WD
AFULL, AEMPTY
This is the input data bus and is 18 bits wide. Not all 18
bits are valid in all configurations. When a data width
less than 18 is specified, unused higher-order signals
must be grounded (Table 2-9).
These are programmable flags and will be asserted on
the threshold specified by AFVAL and AEVAL,
respectively.
When the number of words stored in the FIFO reaches
the amount specified by AEVAL while reading, the
AEMPTY output will go HIGH. Likewise, when the
number of words stored in the FIFO reaches the amount
specified by AFVAL while writing, the AFULL output will
go HIGH.
RD
This is the output data bus and is 18 bits wide. Not all 18
bits are valid in all configurations. Like the WD bus, high-
order bits become unusable if the data width is less than
18. The output data on unused pins is undefined
(Table 2-9).
AFVAL, AEVAL
The AEVAL and AFVAL pins are used to specify the
almost-empty and almost-full threshold values. They are
12-bit signals. For more information on these signals,
refer to the "FIFO Flag Usage Considerations" section.

ESTOP and FSTOP Usage
The ESTOP pin is used to stop the read counter from
counting any further once the FIFO is empty (i.e., the
EMPTY flag goes HIGH). Likewise, the FSTOP pin is used
to stop the write counter from counting any further once
the FIFO is full (i.e., the FULL flag goes HIGH).
2k×2
1k×4
512×9
256×18
The FIFO counters in the ProASIC3 device start the count
at zero, reach the maximum depth for the configuration
(e.g., 511 for a 512×9 configuration), and then restart at
zero. An example application for ESTOP, where the read
counter keeps counting, would be writing to the FIFO
once and reading the same content over and over
without doing another write.
ESTOP, FSTOP
ESTOP is used to stop the FIFO read counter from further
counting once the FIFO is empty (i.e., the EMPTY flag
goes HIGH). A HIGH on this signal inhibits the counting.
FSTOP is used to stop the FIFO write counter from further
counting once the FIFO is full (i.e., the FULL flag goes
HIGH). A HIGH on this signal inhibits the counting.
FIFO Flag Usage Considerations
The AEVAL and AFVAL pins are used to specify the 12-bit
AEMPTY and AFULL threshold values. The FIFO contains
separate 12-bit write address (WADDR) and read address
(RADDR) counters. WADDR is incremented every time a
write operation is performed, and RADDR is incremented
every time a read operation is performed. Whenever the
difference between WADDR and RADDR is greater than
or equal to AFVAL, the AFULL output is asserted.
Likewise, whenever the difference between WADDR and
RADDR is less than or equal to AEVAL, the AEMPTY
output is asserted. To handle different read and write
aspect ratios, AFVAL and AEVAL are expressed in terms
of total data bits instead of total data words. When users
specify AFVAL and AEVAL in terms of read or write
words, the SmartGen tool translates them into bit
addresses and configures these signals automatically.
SmartGen configures the AFULL flag to assert when the
write address exceeds the read address by at least a
predefined value. In a 2k×8 FIFO, for example, a value of
1,500 for AFVAL means that the AFULL flag will be
asserted after a write when the difference between the
write address and the read address reaches 1,500 (there
have been at least 1,500 more writes than reads). It will
stay asserted until the difference between the write and
read addresses drops below 1,500.
For more information on these signals, refer to "ESTOP
and FSTOP Usage" section.
FULL, EMPTY
When the FIFO is full and no more data can be written,
the FULL flag asserts HIGH. The FULL flag is synchronous
to WCLK to inhibit writing immediately upon detection
of a full condition and to prevent overflows. Since the
write address is compared to a resynchronized (and thus
time-delayed) version of the read address, the FULL flag
will remain asserted until two WCLK active edges after a
read operation eliminates the full condition.
When the FIFO is empty and no more data can be read,
the EMPTY flag asserts HIGH. The EMPTY flag is
synchronous to RCLK to inhibit reading immediately
upon detection of an empty condition and to prevent
underflows. Since the read address is compared to a
resynchronized (and thus time-delayed) version of the
write address, the EMPTY flag will remain asserted until
two RCLK active edges after a write operation removes
the empty condition.
For more information on these signals, refer to the "FIFO
Flag Usage Considerations" section.
v2.0
2-27
Automotive ProASIC3 Flash Family FPGAs
The AEMPTY flag is asserted when the difference
between the write address and the read address is less
than a predefined value. In the example above, a value
of 200 for AEVAL means that the AEMPTY flag will be
asserted when a read causes the difference between the
write address and the read address to drop to 200. It will
stay asserted until that difference rises above 200. Note
that the FIFO can be configured with different read and
write widths; in this case, the AFVAL setting is based on
the number of write data entries, and the AEVAL setting
is based on the number of read data entries. For aspect
ratios of 512×9 and 256×18, only 4,096 bits can be
addressed by the 12 bits of AFVAL and AEVAL. The
number of words must be multiplied by 8 and 16 instead
of 9 and 18. The SmartGen tool automatically uses the
proper values. To avoid halfwords being written or read,
which could happen if different read and write aspect
ratios were specified, the FIFO will assert FULL or EMPTY
as soon as at least one word cannot be written or read.
For example, if a two-bit word is written and a four-bit
word is being read, the FIFO will remain in the empty
state when the first word is written. This occurs even if
the FIFO is not completely empty, because in this case, a
complete word cannot be read. The same is applicable in
the full state. If a four-bit word is written and a two-bit
word is read, the FIFO is full and one word is read. The
FULL flag will remain asserted because a complete word
cannot be written at this point.
Advanced I/Os
Introduction
Automotive ProASIC3 devices feature a flexible I/O
structure, supporting a range of mixed voltages (1.5 V,
1.8 V, 2.5 V, and 3.3 V) through
a bank-selectable
voltage. Table 2-10 on page 2-29 shows the voltages and
compatible I/O standards. I/Os provide programmable
slew rates, drive strengths, and weak pull-up and pull-
down circuits. 3.3 V PCI and 3.3 V PCI-X are 5 V–tolerant.
See the "5 V Input Tolerance" section on page 2-36 for
possible implementations of 5 V tolerance.
All I/Os are in a known state during power-up, and any
power-up sequence is allowed without current impact.
Refer to the "I/O Power-Up and Supply Voltage
Thresholds for Power-On Reset (Commercial and
Industrial)" section on page 3-4 for more information.
During power-up, before reaching activation levels, the
I/O input and output buffers are disabled while the weak
pull-up is enabled. Activation levels are described in
Table 3-2 on page 3-2.
I/O Tile
The Automotive ProASIC3 I/O tile provides a flexible,
programmable structure for implementing
a large
number of I/O standards. In addition, the registers
available in the I/O tile in selected I/O banks can be used
to support high-performance register inputs and
outputs, with register enable if desired (Figure 2-24 on
page 2-31). The registers can also be used to support the
JESD-79C Double Data Rate (DDR) standard within the
I/O structure (see the "Double Data Rate (DDR) Support"
section on page 2-32 for more information).
As depicted in Figure 2-24 on page 2-31, all I/O registers
share one CLR port. The output register and output
enable register share one CLK port. Refer to the "I/O
Registers" section on page 2-31 for more information.

Table 2-11 shows the required voltage compatibility
values for each of these voltages.
I/O Banks and I/O Standards Compatibility
I/Os are grouped into I/O voltage banks. There are four I/O
banks on the A3P250 and A3P1000. The A3P060 and
A3P125 have two I/O banks. Each I/O voltage bank has
dedicated I/O supply and ground voltages (VMV/GNDQ for
input buffers and VCCI/GND for output buffers). Because
of these dedicated supplies, only I/Os with compatible
standards can be assigned to the same I/O voltage bank.
For more information about I/O and global assignments
to I/O banks in a device, refer to the specific pin table for
the device in the "Package Pin Assignments" section on
page 4-1 and the "User I/O Naming Convention" section
on page 2-46.

I/O Banks
Automotive ProASIC3 I/Os are divided into multiple
technology banks. The ProASIC3 family has two to four
banks, and the number of banks is device-dependent.
Standard Plus I/O banks offer LVTTL/LVCMOS and PCI
single-ended I/O standards. These banks are available on
the north and south sides of A3P250 and A3P1000.
A3P060 and A3P125 support two I/O banks, whereas
A3P250 and A3P1000 support four I/O banks. The bank
types have different characteristics, such as drive strength,
the I/O standards supported, and timing and power
differences.
Table 2-12 shows the I/O bank types, devices and bank
locations supported, drive strength, slew rate control,
and supported standards.
There are two types of banks in the Automotive ProASIC3
family: Advanced I/O banks and Standard Plus I/O banks.

I/O Registers
Each I/O module contains several input, output, and enable registers. Refer to Figure 2-24 for a simplified
representation of the I/O block.
The number of input registers is selected by a set of switches (not shown in Figure 2-24) between registers to
implement single-ended or differential data transmission to and from the FPGA core. The Designer software sets these
switches for the user.
A common CLR/PRE signal is employed by all I/O registers when I/O register combining is used. Input Register 2 does
not have a CLR/PRE pin, as this register is used for DDR implementation. The I/O register combining must satisfy certain
rules. For more information, refer to the ProASIC3/E I/O Usage Guide.

Automotive ProASIC3 Flash Family FPGAs
Each I/O tile on Automotive ProASIC3 devices supports
DDR inputs.
Double Data Rate (DDR) Support
Automotive ProASIC3 devices support 350 MHz DDR
inputs and outputs. In DDR mode, new data is present on
every transition of the clock signal. Clock and data lines
have identical bandwidths and signal integrity
requirements, making them very efficient for
implementing very high-speed systems.
Output Support for DDR
The basic DDR output structure is shown in Figure 2-26 on
page 2-33. New data is presented to the output every half
clock cycle. Note: DDR macros and I/O registers do not
require additional routing. The combiner automatically
recognizes the DDR macro and pushes its registers to the
I/O register area at the edge of the chip. The routing
delay from the I/O registers to the I/O buffers is already
taken into account in the DDR macro.
High-speed DDR interfaces can be implemented using
LVDS. The DDR feature is primarily implemented in the
FPGA core periphery and is not limited to any I/O
standard.
Refer to the Actel application note Using DDR for
ProASIC3/E Devices for more information.
Input Support for DDR
The basic structure to support a DDR input is shown in
Figure 2-25. Three input registers are used to capture
incoming data, which is presented to the core on each
rising edge of the I/O register clock.

Cold-Sparing Support
Electrostatic Discharge (ESD) Protection
Automotive ProASIC3 devices are tested per JEDEC
Standard JESD22-A114-B.
Cold-sparing means that a subsystem with no power
applied (usually a circuit board) is electrically connected
to the system that is in operation. This means that all
input buffers of the subsystem must present very high
input impedance with no power applied so as not to
disturb the operating portion of the system.
Automotive ProASIC3 devices contain clamp diodes at
every I/O, global, and power pad. Clamp diodes protect
all device pads against damage from ESD as well as from
excessive voltage transients.
For Automotive ProASIC3 devices, since the I/O clamp
diode is always active, cold-sparing can be accomplished
either by employing a bus switch to isolate the device I/Os
from the rest of the system or by driving each Automotive
ProASIC3 I/O pin to 0 V.
Automotive ProASIC3 devices are tested to the following
models: the Human Body Model (HBM) with a tolerance
of 2,000 V, the Machine Model (MM) with a tolerance of
250 V, and the Charged Device Model (CDM) with a
tolerance of 200 V.
If the resistor is chosen, the resistor value must be
calculated based on decoupling capacitance on a given
power supply on the board (this decoupling capacitance
is in parallel with the resistor). The RC time constant
should ensure full discharge of supplies before cold-
sparing functionality is required. The resistor is necessary
to ensure that the power pins are discharged to ground
every time there is an interruption of power to the
device.
Each I/O has two clamp diodes. One diode has its
positive (P) side connected to the pad and its negative
(N) side connected to VCCI. The second diode has its P
side connected to GND and its N side connected to the
pad. During operation, these diodes are normally
biased in the off state, except when transient voltage is
significantly above VCCI or below GND levels.
In Automotive ProASIC3 devices, the clamp diode is
always on and cannot be switched off.
Refer to Table 2-16 for more information about the I/O
standards and the clamp diode.

LVCMOS 3.3 V, LVCMOS 2.5 V, and LVCMOS 2.5 V / 5.0 V
configurations are used (see Table 2-16 on page 2-35 for
more details). There are four recommended solutions for
achieving 5 V receiver tolerance (see Figure 2-27 to
Figure 2-30 on page 2-39 for details of board and macro
setups). All the solutions meet a common requirement of
limiting the voltage at the input to 3.6 V or less. In fact,
the I/O absolute maximum voltage rating is 3.6 V, and
any voltage above 3.6 V may cause long-term gate oxide
failures.

The board-level design must ensure that the reflected
waveform at the pad does not exceed the limits provided
in Table 3-2 on page 3-2. This is a requirement to ensure
long-term reliability.
R1 = 220 Ω ( 5%), P(r1)min = 0.018 Ω
R2 = 390 Ω ( 5%), P(r2)min = 0.032 Ω
Imax_tx = 5.5 V / (220 × 0.95 + 390 × 0.95 + 10) = 9.17 mA
This scheme will also work for
a 3.3 V PCI/PCI-X
configuration, but the internal diode should not be used for
clamping, and the voltage must be limited by the two
external resistors as explained below. Relying on the
diode clamping would create an excessive pad DC
voltage of 3.3 V + 0.7 V = 4 V.
t
RISE = tFALL = 4 ns at C_pad_load = 10 pF (includes up to
25% safety margin)
tRISE = tFALL = 20 ns at C_pad_load = 50 pF (includes up to
25% safety margin)
Other values of resistors are also allowed as long as the
resistors are sized appropriately to limit the voltage at
the receiving end to 2.5 V < Vin (rx) < 3.6 V when the
transmitter sends a logic 1. This range of Vin_dc (rx) must
be assured for any combination of transmitter supply
(5 V 0.5 V), transmitter output resistance, and board
resistor tolerances.
Here are some examples of possible resistor values
(based on a simplified simulation model with no line
effects and 10 Ω transmitter output resistance, where
Rtx_out_high = (VCCI – VOH) / IOH, Rtx_out_low = VOL / IOL).

5 V Output Tolerance
Automotive ProASIC3 I/Os must be set to 3.3 V LVTTL or
3.3 V LVCMOS mode to reliably drive 5 V TTL receivers. It
is also critical that there be NO external I/O pull-up
resistor to 5 V, since this resistor would pull the I/O pad
voltage beyond the 3.6 V absolute maximum value and
consequently cause damage to the I/O.
When set to 3.3 V LVTTL or 3.3 V LVCMOS mode,
Automotive ProASIC3 I/Os can directly drive signals into
5 V TTL receivers. In fact, VOL = 0.4 V and VOH = 2.4 V in
both 3.3 V LVTTL and 3.3 V LVCMOS modes exceeds the
VIL = 0.8 V and VIH = 2 V level requirements of 5 V TTL
receivers. Therefore, level
1 and level 0 will be
recognized correctly by 5 V TTL receivers.
Simultaneous Switching Outputs (SSOs) and Printed Circuit Board Layout
SSOs can cause signal integrity problems on adjacent
signals that are not part of the SSO bus. Both inductive
and capacitive coupling parasitics of bond wires inside
packages and of traces on PCBs will transfer noise from
SSO busses onto signals adjacent to those busses.
Additionally, SSOs can produce ground bounce noise and
VCCI dip noise. These two noise types are caused by
rapidly changing currents through GND and VCCI
package pin inductances during switching activities
(EQ 2-1 and EQ 2-2).
should be done both on the board and inside the
package unless otherwise described.
In-package shielding can be achieved in several ways; the
required shielding will vary depending on whether pins
next to the SSO bus are LVTTL/LVCMOS inputs,
LVTTL/LVCMOS outputs, or GTL/SSTL/HSTL/LVDS/LVPECL
inputs and outputs. Board traces in the vicinity of the
SSO bus have to be adequately shielded from mutual
coupling and inductive noise that can be generated by
the SSO bus. Also, noise generated by the SSO bus needs
to be reduced inside the package.
Ground bounce noise voltage = L(GND) × di/dt
PCBs perform an important function in feeding stable
supply voltages to the IC and, at the same time,
maintaining signal integrity between devices.

VCCI dip noise voltage = L(VCCI) × di/dt

Weak Pull-Up and Weak Pull-Down Resistors
Automotive ProASIC3 devices support optional weak pull-up and pull-down resistors on each I/O pin. When the I/O is
pulled up, it is connected to the VCCI of its corresponding I/O bank. When it is pulled down, it is connected to GND.

The output slew rate and multiple drive strength
controls are available in LVTTL/LVCMOS 3.3 V, LVCMOS
2.5 V, LVCMOS 2.5 V / 5.0 V input, LVCMOS 1.8 V, and
LVCMOS 1.5 V. All other I/O standards have a high output
slew rate by default.
Slew Rate Control and Drive Strength
Automotive ProASIC3 devices support output slew rate
control: high and low. Actel recommends the high slew
rate option to minimize the propagation delay. This
high-speed option may introduce noise into the system if
appropriate signal integrity measures are not adopted.
Selecting a low slew rate reduces this kind of noise but
adds some delays in the system. Low slew rate is
recommended when bus transients are expected. Drive
strength should also be selected according to the design
requirements and noise immunity of the system.
For Automotive ProASIC3 devices, refer to Table 2-20 and
Table 2-21 for more information about the slew rate and
drive strength specification.

User I/O Naming Convention
Due to the comprehensive and flexible nature of ProASIC3 device user I/Os, a naming scheme is used to show the
details of each I/O (Figure 2-37 and Figure 2-38 on page 2-47). The name identifies to which I/O bank it belongs, as well
as pairing and pin polarity for differential I/Os.
I/O Nomenclature = Gmn/IOuxwBy
Gmn is only used for I/Os that also have CCC access—i.e., global pins.
G
= Global
m
= Global pin location associated with each CCC on the device: A (northwest corner), B (northeast corner), C (east
middle), D (southeast corner), E (southwest corner), and F (west middle)
n
= Global input MUX and pin number of the associated Global location m, either A0, A1, A2, B0, B1, B2, C0, C1, or
C2. Figure 2-15 on page 2-17 shows the three input pins per clock source MUX at CCC location m.
u
x
= I/O pair number in the bank, starting at 00 from the northwest I/O bank and proceeding in a clockwise direction
= P (Positive) or N (Negative) for differential pairs, or R (Regular—single-ended) for the I/Os that support single-
ended and voltage-referenced I/O standards only. U (Positive-LVDS, DDR LVDS, BLVDS, and M-LVDS only) or V
(Negative-LVDS, DDR LVDS, BLVDS, and M-LVDS only) restrict the I/O differential pair from being selected as an
LVPECL pair.
w
= D (Differential Pair), P (Pair), or S (Single-Ended). D (Differential Pair) if both members of the pair are bonded
out to adjacent pins or are separated only by one GND or NC pin; P (Pair) if both members of the pair are
bonded out but do not meet the adjacency requirement; or S (Single-Ended) if the I/O pair is not bonded out.
For Differential (D) pairs, adjacency for ball grid packages means only vertical or horizontal. Diagonal
adjacency does not meet the requirements for a true differential pair.

Supply Pins
GND. VMV and VCCI should be at the same voltage within
a given I/O bank. Used VMV pins must be connected to
the corresponding VCCI pins of the same bank (i.e., VMV0
to VCCIB0, VMV1 to VCCIB1, etc.).

CCPLF
GNDQ

VCCPLF should be tied to either the power supply or GND.
Quiet ground supply voltage to input buffers of I/O
banks. Within the package, the GNDQ plane is
decoupled from the simultaneous switching noise
originated from the output buffer ground domain. This
minimizes the noise transfer within the package and
improves input signal integrity. GNDQ must always be
connected to GND on the board.
V
PLL Ground
COMPLF
Ground to analog PLL power supplies. Unused VCOMPLF
pins should be connected to GND.
V
JTAG Supply Voltage
JTAG
Automotive ProASIC3 devices have a separate bank for
the dedicated JTAG pins. The JTAG pins can be run at any
voltage from 1.5 V to 3.3 V (nominal). Isolating the JTAG
power supply in a separate I/O bank gives greater
flexibility in supply selection and simplifies power supply
and PCB design. If the JTAG interface is neither used nor
planned for use, the VJTAG pin together with the TRST
pin could be tied to GND. It should be noted that VCC is
required to be powered for JTAG operation; VJTAG alone
is insufficient. If a device is in a JTAG chain of
interconnected boards, the board containing the
Automotive ProASIC3 device can be powered down,
provided both VJTAG and VCC to the Automotive
ProASIC3 part remain powered; otherwise, JTAG signals
will not be able to transition the Automotive ProASIC3
device, even in bypass mode.
V
Core Supply Voltage
CC
Supply voltage to the FPGA core, nominally 1.5 V. VCC is
required for powering the JTAG state machine in
addition to VJTAG. Even when an Automotive ProASIC3
device is in bypass mode in
a
JTAG chain of
interconnected devices, both VCC and VJTAG must remain
powered to allow JTAG signals to pass through the
Automotive ProASIC3 device.
V
Bx
I/O Supply Voltage
CCI
Supply voltage to the bank's I/O output buffers and I/O
logic. Bx is the I/O bank number. There are eight I/O
banks on Automotive ProASIC3 devices plus a dedicated
VJTAG bank. Each bank can have a separate VCCI
connection. All I/Os in a bank will run off the same VCCIBx
supply. VCCI can be 1.5 V, 1.8 V, 2.5 V, or 3.3 V, nominal
voltage. Unused I/O banks should have their
corresponding VCCI pins tied to GND.
V
Programming Supply Voltage
PUMP
Automotive ProASIC3 devices support single-voltage ISP
of the configuration flash and FlashROM. For
programming, VPUMP should be 3.3 V nominal. During
normal device operation, VPUMP can be left floating or
can be tied (pulled up) to any voltage between 0 V and
3.6 V. Programming power supply voltage (VPUMP) range
is 3.3 V +/- 5%.
VMVx
I/O Supply Voltage (quiet)
Quiet supply voltage to the input buffers of each I/O
bank. x is the bank number. Within the package, the
VMV plane is decoupled from the simultaneous
switching noise originated from the output buffer VCCI
domain. This minimizes the noise transfer within the
package and improves input signal integrity. Each bank
must have at least one VMV connection, and no VMV
should be left unconnected. All I/Os in a bank run off the
same VMVx supply. VMV is used to provide a quiet supply
voltage to the input buffers of each I/O bank. VMVx can
be 1.5 V, 1.8 V, 2.5 V, or 3.3 V, nominal voltage. Unused I/O
banks should have their corresponding VMV pins tied to
When the VPUMP pin is tied to ground, it will shut off the
charge pump circuitry, resulting in no sources of
oscillation from the charge pump circuitry.
For proper programming, 0.01 µF and 0.33 µF capacitors
(both rated at 16 V) are to be connected in parallel
across VPUMP and GND, and positioned as close to the
FPGA pins as possible.

User Input/Output
The I/O pin functions as an input, output, tristate, or

TCK
Test Clock
During programming, I/Os become tristated and weakly
pulled up to VCCI. With VCCI, VMV, and VCC supplies
continuously powered up, when the device transitions
from programming to operating mode, the I/Os are
instantly configured to the desired user configuration.
Test clock input for JTAG boundary scan, ISP, and UJTAG.
The TCK pin does not have an internal pull-up/-down
resistor. If JTAG is not used, Actel recommends tying off
TCK to GND through a resistor placed close to the FPGA
pin. This prevents JTAG operation in case TMS enters an
undesired state.
Unused I/Os are configured as follows:
•

•
Output buffer is disabled (with tristate value of high
impedance)
Note that to operate at all VJTAG voltages, 500 Ω to 1 kΩ
will satisfy the requirements. Refer to Table 2-22 for

JTAG Pins
Automotive ProASIC3 devices have a separate bank for
the dedicated JTAG pins. The JTAG pins can be run at any
voltage from 1.5 V to 3.3 V (nominal). VCC must also be
powered for the JTAG state machine to operate, even if
the device is in bypass mode; VJTAG alone is insufficient.
Both VJTAG and VCC to the Automotive ProASIC3 part
must be supplied to allow JTAG signals to transition the

chosen from Table 2-22 on page 2-49 and must satisfy
the parallel resistance value requirement. The values in
Table 2-22 on page 2-49 correspond to the resistor
recommended when a single device is used and the
equivalent parallel resistor when multiple devices are
connected via a JTAG chain.

In critical applications, an upset in the JTAG circuit could
allow entrance to an undesired JTAG state. In such cases,
Actel recommends tying off TRST to GND through a
resistor placed close to the FPGA pin.
With the Designer software, a user can lock the design
pins before layout while minimally impacting the results
of place-and-route. Additionally, Actel back-annotation
flow is compatible with all the major simulators. Another
tool included in the Designer software is the SmartGen
core generator, which easily creates popular and
commonly used logic functions for implementation into
your schematic or HDL design.
Note that to operate at all VJTAG voltages, 500 Ω to 1 kΩ
will satisfy the requirements.

The Automotive ProASIC3 family of FPGAs is fully
supported by both Actel Libero IDE and Designer FPGA
development software. Actel Libero IDE is an integrated
design manager that seamlessly integrates design tools
while guiding the user through the design flow,
managing all design and log files and passing necessary
design data among tools. Additionally, Libero IDE allows
users to integrate both schematic and HDL synthesis into
a single flow and verify the entire design in a single

The Automotive ProASIC3 device can be serialized with a
unique identifier stored in the FlashROM of each device.
Serialization is an automatic assignment of serial
numbers that are stored within the STAPL file used for
programming. The area of the FlashROM used for
holding such identifiers is defined using SmartGen, and
the range of serial numbers to be used is defined at the
time of STAPL file generation with FlashPoint. Serial
number values for STAPL file generation can even be
read from
a file of predefined values. Serialized
programming using a serialized STAPL file can be done
through Actel In-House Programming (IHP), an external
vendor using Silicon Sculptor software, or the ISP
capabilities of the FlashPro software.
Actel Designer software is a place-and-route tool and
provides a comprehensive suite of backend support tools
for FPGA development. The Designer software includes

Security
ISP
Automotive ProASIC3 devices have a built-in 128-bit AES
decryption core. The decryption core facilitates secure in-
system programming of the FPGA core array fabric and
the FlashROM. The FlashROM and the FPGA core fabric
can be programmed independently of each other,
allowing the FlashROM to be updated without the need
for change to the FPGA core fabric. The AES master key is
stored in on-chip nonvolatile memory (flash). The AES
master key can be preloaded into parts in a secure
programming environment (such as the Actel In-House
Programming center), and then "blank" parts can be
shipped to an untrusted programming or manufacturing
center for final personalization with an AES-encrypted
bitstream. Late-stage product changes or personalization
can be implemented easily and securely by simply
sending a STAPL file with AES-encrypted data. Secure
remote field updates over public networks (such as the
Internet) are possible by sending and programming a
STAPL file with AES-encrypted data.
Automotive ProASIC3 devices support IEEE 1532 ISP via
JTAG and require a single VPUMP voltage of 3.3 V during
programming. In addition, programming via
a
microcontroller in a target system can be achieved. See
the application note In-System Programming (ISP) in
ProASIC3/E Using FlashPro3 for more details.
JTAG 1532
Automotive ProASIC3 devices support the JTAG-based
IEEE 1532 standard for ISP. As part of this support, when
an Automotive ProASIC3 device is in an unprogrammed
state, all user I/O pins are disabled. This is achieved by
keeping the global IO_EN signal deactivated, which also
has the effect of disabling the input buffers. The
SAMPLE/PRELOAD instruction captures the status of pads
in parallel and shifts them out as new data is shifted in
for loading into the Boundary Scan Register. When the
Automotive ProASIC3 device is in an unprogrammed
state, the SAMPLE/PRELOAD instruction has no effect on
I/O status; however, it will continue to shift in new data
to be loaded into the BSR. Therefore, when
SAMPLE/PRELOAD is used on an unprogrammed device,
the BSR will be loaded with undefined data. Refer to the
In-System Programming (ISP) in ProASIC3/E Using
FlashPro3 application note for more details.
128-Bit AES Decryption
The 128-bit AES standard (FIPS-192) block cipher is the
NIST (National Institute of Standards and Technology)
replacement for DES (Data Encryption Standard
FIPS46-2). AES has been designed to protect sensitive
government information well into the 21st century. It
replaces the aging DES, which NIST adopted in 1977 as a
Federal Information Processing Standard used by federal
agencies to protect sensitive, unclassified information.
The 128-bit AES standard has 3.4 × 1038 possible 128-bit
key variants, and it has been estimated that it would
take 1,000 trillion years to crack 128-bit AES cipher text
using exhaustive techniques. Keys are stored (securely) in
Automotive ProASIC3 devices in nonvolatile flash
memory. All programming files sent to the device can be
authenticated by the part prior to programming to
ensure that bad programming data is not loaded into
the part that may possibly damage it. All programming
verification is performed on-chip, ensuring that the
contents of Automotive ProASIC3 devices remain secure.
For JTAG timing information on setup, hold, and fall
times, refer to the FlashPro User’s Guide.
Boundary Scan
Automotive ProASIC3 devices are compatible with IEEE
Standard 1149.1, which defines a hardware architecture
and the set of mechanisms for boundary scan testing.
The basic Automotive ProASIC3 boundary scan logic
circuit is composed of the TAP controller, test data
registers, and instruction register (Figure 2-41 on page 2-
53). This circuit supports all mandatory IEEE 1149.1
instructions (EXTEST, SAMPLE/PRELOAD, and BYPASS)
and the optional IDCODE instruction (Table 2-23).
Table 2-23 • Boundary Scan Opcodes
AES decryption can also be used on the 1,024-bit
FlashROM to allow for secure remote updates of the
FlashROM contents. This allows for easy, secure support
for subscription model products. See the application
note ProASIC3/E Security for more details.

Each test section is accessed through the TAP, which has
five associated pins: TCK (test clock input), TDI, TDO (test
data input and output), TMS (test mode selector), and
TRST (test reset input). TMS, TDI, and TRST are equipped
with pull-up resistors to ensure proper operation when
no input data is supplied to them. These pins are
dedicated for boundary scan test usage. Refer to the
"JTAG Pins" section on page 2-49 for pull-up/-down
recommendations for TDO and TCK pins. Table 2-24 gives
pull-down recommendations for the TRST and TCK
pins.
The TAP controller is a 4-bit state machine (16 states)
that operates as shown in Figure 2-40. The 1s and 0s
represent the values that must be present on TMS at a
rising edge of TCK for the given state transition to occur.
IR and DR indicate that the instruction register or the
data register is operating in that state.
The TAP controller receives two control inputs (TMS and
TCK) and generates control and clock signals for the rest
of the test logic architecture. On power-up, the TAP
controller enters the Test-Logic-Reset state. To guarantee
a reset of the controller from any of the possible states,
TMS must remain HIGH for five TCK cycles. The TRST pin
can also be used to asynchronously place the TAP
controller in the Test-Logic-Reset state.

Automotive ProASIC3 devices support three types of test
data registers: bypass, device identification, and
boundary scan. The bypass register is selected when no
other register needs to be accessed in a device. This
speeds up test data transfer to other devices in a test
data path. The 32-bit device identification register is a
shift register with four fields (LSB, ID number, part
number, and version). The boundary scan register
observes and controls the state of each I/O pin. Each I/O
cell has three boundary scan register cells, each with
serial-in, serial-out, parallel-in, and parallel-out pins.

I/O Power-Up and Supply Voltage Thresholds for Power-On Reset (Commercial and
Industrial)
Sophisticated power-up management circuitry is
designed into every ProASIC3 device. These circuits
ensure easy transition from the powered-off state to the
powered-up state of the device. The many different
supplies can power up in any sequence with minimized
current spikes or surges. In addition, the I/O will be in a
known state through the power-up sequence. The basic
principle is shown in Figure 3-2.
VCC Trip Point:
Ramping up: 0.6 V < trip_point_up < 1.1 V
Ramping down: 0.5 V < trip_point_down < 1 V
VCC and VCCI ramp-up trip points are about 100 mV
higher than ramp-down trip points. This specifically
built-in hysteresis prevents undesirable power-up
oscillations and current surges. Note the following:
•
During programming, I/Os become tristated and
weakly pulled up to VCCI
JTAG supply, PLL power supplies, and charge pump
PUMP supply have no influence on I/O behavior.
There are five regions to consider during power-up.

ProASIC3 I/Os are activated only if ALL of the following
three conditions are met:

Thermal Characteristics
Introduction
The temperature variable in the Actel Designer software refers to the junction temperature, not the ambient
temperature. This is an important distinction because dynamic and static power consumption cause the chip junction
to be higher than the ambient temperature.
EQ 3-1 can be used to calculate junction temperature.
TJ = Junction Temperature = ΔT + TA

Guidelines
Toggle Rate Definition
A toggle rate defines the frequency of a net or logic
element relative to a clock. It is a percentage. If the
toggle rate of a net is 100%, this means that this net
switches at half the clock frequency. Below are some
examples:
Bit 7 (MSB) = 0.78125%
Average toggle rate = (100% + 50% + 25% +
12.5% + . . . + 0.78125%) / 8.
Enable Rate Definition
•
The average toggle rate of a shift register is 100%
because all flip-flop outputs toggle at half of the
clock frequency.
Output enable rate is the average percentage of time
during which tristate outputs are enabled. When
nontristate output buffers are used, the enable rate
should be 100%.
•
The average toggle rate of an 8-bit counter is
25%:

For example, at 110°C, the short current condition would have to be sustained for more than three months to cause a
reliability concern. The I/O design does not contain any short circuit protection, but such protection would only be
needed in extremely prolonged stress conditions.

Note: *The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the noise is low, the rise time and
fall time of input buffers can be increased beyond the maximum value. The longer the rise/fall times, the more susceptible the
input signal is to the board noise. Actel recommends signal integrity evaluation/characterization of the system to ensure there is no
excessive noise coupling into input signals.

Physical Implementation

instantiates a differential I/O macro in the design.
pins are needed. It also requires external resistor
termination.
The full implementation of the LVDS transmitter and
receiver is shown in an example in Figure 3-12. The
building blocks of the LVDS transmitter-receiver are one
transmitter macro, one receiver macro, three board
resistors at the transmitter end, and one resistor at the
receiver end. The values for the three driver resistors are
different from those used in the LVPECL implementation
because the output standard specifications are different.
Differential I/Os can also be used in conjunction with the
embedded Input Register (InReg), Output Register
(OutReg), Enable Register (EnReg), and Double Data
Rate (DDR). However, there is no support for
bidirectional I/Os or tristates with the LVPECL standards.
LVDS
Along with LVDS I/O, ProASIC3 also supports Bus LVDS
structure and Multipoint LVDS (M-LVDS) configuration
(up to 40 nodes).
Low-Voltage Differential Signaling (ANSI/TIA/EIA-644) is
a high-speed, differential I/O standard. It requires that
one data bit be carried through two signal lines, so two

BLVDS/M-LVDS
Bus LVDS (BLVDS) and Multipoint LVDS (M-LVDS)
specifications extend the existing LVDS standard to high-
performance multipoint bus applications. Multidrop and
multipoint bus configurations may contain any
combination of drivers, receivers, and transceivers. Actel
LVDS drivers provide the higher drive current required by
BLVDS and M-LVDS to accommodate the loading. The
drivers require series terminations for better signal quality
and to control voltage swing. Termination is also required
at both ends of the bus since the driver can be located
anywhere on the bus. These configurations can be
implemented using the TRIBUF_LVDS and BIBUF_LVDS
macros along with appropriate terminations. Multipoint
designs using Actel LVDS macros can achieve up to
200 MHz with a maximum of 20 loads. A sample
application is given in Figure 3-13. The input and output
buffer delays are available in the LVDS section in Table 3-
84.
Example: For a bus consisting of 20 equidistant loads, the
following terminations provide the required differential
voltage, in worst-case Industrial operating conditions, at
the farthest receiver: RS = 60 Ω and RT = 70 Ω, given
Z0 = 50 Ω (2") and Zstub = 50 Ω (~1.5").

Global Resource Characteristics
A3P250 Clock Tree Topology
Clock delays are device-specific. Figure 3-28 is an example of a global tree used for clock routing. The global tree
presented in Figure 3-28 is driven by a CCC located on the west side of the A3P250 device. It is used to drive all D-flip-
flops in the device.

Automotive ProASIC3 Flash Family FPGAs
Global Tree Timing Characteristics
Global clock delays include the central rib delay, the spine delay, and the row delay. Delays do not include I/O input
buffer clock delays, as these are I/O standard–dependent, and the clock may be driven and conditioned internally by
the CCC module. For more details on clock conditioning capabilities, refer to the "Clock Conditioning Circuits" section
on page 2-13. Table 3-114 on page 3-80 to Table 3-124 on page 3-97 present minimum and maximum global clock
delays within each device. Minimum and maximum delays are measured with minimum and maximum loading.

Datasheet Information
Datasheet Categories
In order to provide the latest information to designers, some datasheets are published before data has been fully
characterized. Datasheets are designated as “Product Brief,” “Advanced,” “Production,” and “Web-only.” The
definition of these categories are as follows:
Product Brief
The product brief is a summarized version of a advanced datasheet (advanced or production) containing general
product information. This brief gives an overview of specific device and family information.
Advanced
This datasheet version contains initial estimated information based on simulation, other products, devices, or speed
grades. This information can be used as estimates, but not for production.
Datasheet Supplement
The datasheet supplement gives specific device information for a derivative family that differs from the general family
datasheet. The supplement is to be used in conjunction with the datasheet to obtain more detailed information and
for specifications that do not differ between the two families.
Unmarked (production)
This datasheet version contains information that is considered to be final.
Export Administration Regulations (EAR)
The products described in this datasheet are subject to the Export Administration Regulations (EAR). They could
require an approved export license prior to export from the United States. An export includes release of product or
disclosure of technology to a foreign national inside or outside the United States.
