Description
The ATF1502AS is a high-performance, high-density complex programmable logic device
(CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 32 logic macrocells
and up to 36 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic
PLDs. The ATF1502AS’s enhanced routing switch matrices increase usable gate count and
the odds of successful pin-locked design modifications.
The ATF1502AS has up to 32 bi-directional I/O pins and four dedicated input pins, depending
on the type of device package selected. Each dedicated pin can also serve as a global control
signal, register clock, register reset or output enable. Each of these control signals can be
selected for use individually within each macrocell.

Each of the 32 macrocells generates a buried feedback that goes to the global bus. Each input
and I/O pin also feeds into the global bus. The switch matrix in each logic block then selects 40
individual signals from the global bus. Each macrocell also generates a foldback logic term
that goes to a regional bus. Cascade logic between macrocells in the ATF1502AS allows fast,
efficient generation of complex logic functions. The ATF1502AS contains four such logic
chains, each capable of creating sum term logic with a fan-in of up to 40 product terms.
The ATF1502AS macrocell, shown in Figure 1, is flexible enough to support highly complex
logic functions operating at high speed. The macrocell consists of five sections: product terms
and product term select multiplexer, OR/XOR/CASCADE logic, a flip-flop, output select and
enable, and logic array inputs.
Unused product terms are automatically disabled by the compiler to decrease power con-
sumption. A security fuse, when programmed, protects the contents of the ATF1502AS. Two
bytes (16 bits) of User Signature are accessible to the user for purposes such as storing
project name, part number, revision or date. The User Signature is accessible regardless of
the state of the security fuse.
The ATF1502AS device is an in-system programmable (ISP) device. It uses the industry stan-
dard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully compliant with JTAG’s Boundary-
scan Description Language (BSDL). ISP allows the device to be programmed without remov-
ing it from the printed circuit board. In addition to simplifying the manufacturing flow, ISP also
allows design modifications to be made in the field via software.

Figure 1. ATF1502AS Macrocell
Product Terms and
Select Mux
Each ATF1502AS macrocell has five product terms. Each product term receives as its inputs
all signals from both the global bus and regional bus.
The product term select multiplexer (PTMUX) allocates the five product terms as needed to
the macrocell logic gates and control signals. The PTMUX programming is determined by the
design compiler, which selects the optimum macrocell configuration.
OR/XOR/
CASCADE Logic
The ATF1502AS’s logic structure is designed to efficiently support all types of logic. Within a
single macrocell, all the product terms can be routed to the OR gate, creating a 5-input
AND/OR sum term. With the addition of the CASIN from neighboring macrocells, this can be
expanded to as many as 40 product terms with little additional delay.
The macrocell’s XOR gate allows efficient implementation of compare and arithmetic func-
tions. One input to the XOR comes from the OR sum term. The other XOR input can be a
product term or a fixed high or low level. For combinatorial outputs, the fixed level input allows
polarity selection. For registered functions, the fixed levels allow DeMorgan minimization of
product terms. The XOR gate is also used to emulate T- and JK-type flip-flops.
Flip-flop
The ATF1502AS’s flip-flop has very flexible data and control functions. The data input can
come from either the XOR gate, from a separate product term or directly from the I/O pin.
Selecting the separate product term allows creation of a buried registered feedback within a
combinatorial output macrocell. (This feature is automatically implemented by the fitter soft-
ware). In addition to D, T, JK and SR operation, the flip-flop can also be configured as a flow-
through latch. In this mode, data passes through when the clock is high and is latched when
the clock is low.
4
ATF1502AS(L)
0995K–PLD–6/05
ATF1502AS(L)
The clock itself can be either one of the Global CLK signals (GCK[0 : 2]) or an individual prod-
uct term. The flip-flop changes state on the clock’s rising edge. When the GCK signal is used
as the clock, one of the macrocell product terms can be selected as a clock enable. When the
clock enable function is active and the enable signal (product term) is low, all clock edges are
ignored. The flip-flop’s asynchronous reset signal (AR) can be either the Global Clear
(GCLEAR), a product term, or always off. AR can also be a logic OR of GCLEAR with a prod-
uct term. The asynchronous preset (AP) can be a product term or always off.
Extra Feedback
The ATF1502AS(L) macrocell output can be selected as registered or combinatorial. The
extra buried feedback signal can be either combinatorial or a registered signal regardless of
whether the output is combinatorial or registered. (This enhancement function is automatically
implemented by the fitter software.) Feedback of a buried combinatorial output allows the cre-
ation of a second latch within a macrocell.
I/O Control
The output enable multiplexer (MOE) controls the output enable signal. Each I/O can be indi-
vidually configured as an input, output or for bi-directional operation. The output enable for
each macrocell can be selected from the true or compliment of the two output enable pins, a
subset of the I/O pins, or a subset of the I/O macrocells. This selection is automatically done
by the fitter software when the I/O is configured as an input, all macrocell resources are still
available, including the buried feedback, expander and cascade logic.
Global Bus/Switch
Matrix
The global bus contains all input and I/O pin signals as well as the buried feedback signal from
all 32 macrocells. The switch matrix in each logic block receives as its inputs all signals from
the global bus. Under software control, up to 40 of these signals can be selected as inputs to
the logic block.
Foldback Bus
Each macrocell also generates a foldback product term. This signal goes to the regional bus
and is available to four macrocells. The foldback is an inverse polarity of one of the macrocell’s
product terms. The four foldback terms in each region allow generation of high fan-in sum
terms (up to nine product terms) with little additional delay.
Programmable
Pin-keeper
Option for
The ATF1502AS offers the option of programming all input and I/O pins so that pin-keeper cir-
cuits can be utilized. When any pin is driven high or low and then subsequently left floating, it
will stay at that previous high or low level. This circuitry prevents unused input and I/O lines
from floating to intermediate voltage levels, which causes unnecessary power consumption
and system noise. The keeper circuits eliminate the need for external pull-up resistors and
eliminate their DC power consumption.
Inputs and I/Os

Speed/Power
Management
The ATF1502AS has several built-in speed and power management features. The
ATF1502AS contains circuitry that automatically puts the device into a low-power standby
mode when no logic transitions are occurring. This not only reduces power consumption dur-
ing inactive periods, but also provides proportional power savings for most applications
running at system speeds below 50 MHz. This feature may be selected as a design option.
To further reduce power, each ATF1502AS macrocell has a reduced-power bit feature. This
feature allows individual macrocells to be configured for maximum power savings. This feature
may be selected as a design option.
The ATF1502AS also has an optional power-down mode. In this mode, current drops to below
10 mA. When the power-down option is selected, either PD1 or PD2 pins (or both) can be
used to power down the part. The power-down option is selected in the design source file.
When enabled, the device goes into power-down when either PD1 or PD2 is high. In the
power-down mode, all internal logic signals are latched and held, as are any enabled outputs.
6
ATF1502AS(L)
0995K–PLD–6/05
ATF1502AS(L)
All pin transitions are ignored until the PD pin is brought low. When the power-down feature is
enabled, the PD1 or PD2 pin cannot be used as a logic input or output. However, the pin’s
macrocell may still be used to generate buried foldback and cascade logic signals.
All power-down AC characteristic parameters are computed from external input or I/O pins,
with reduced-power bit turned on. For macrocells in reduced-power mode (reduced-power bit
turned on), the reduced-power adder, tRPA, must be added to the AC parameters, which
include the data paths tLAD, tLAC, tIC, tACL, tACH and tSEXP
.
The ATF1502AS macrocell also has an option whereby the power can be reduced on a per-
macrocell basis. By enabling this power-down option, macrocells that are not used in an appli-
cation can be turned down, thereby reducing the overall power consumption of the device.
Each output also has individual slew rate control. This may be used to reduce system noise by
slowing down outputs that do not need to operate at maximum speed. Outputs default to slow
switching, and may be specified as fast switching in the design file.
Design
Software
Support
ATF1502AS designs are supported by several third-party tools. Automated fitters allow logic
synthesis using a variety of high-level description languages and formats.
Power-up Reset
The ATF1502AS is designed with a power-up reset, a feature critical for state machine initial-
ization. At a point delayed slightly from VCC crossing VRST, all registers will be initialized, and
the state of each output will depend on the polarity of its buffer. However, due to the asynchro-
nous nature of reset and uncertainty of how VCC actually rises in the system, the following
conditions are required:
1. The VCC rise must be monotonic,
2. After reset occurs, all input and feedback setup times must be met before driving the
clock pin high, and,
3. The clock must remain stable during TD.
The ATF1502AS has two options for the hysteresis about the reset level, VRST, Small and
Large. During the fitting process users may configure the device with the Power-up Reset hys-
teresis set to Large or Small. Atmel POF2JED users may select the Large option by including
the flag “-power_reset” on the command line after “filename.POF”. To allow the registers to be
properly reinitialized with the Large hysteresis option selected, the following condition is
added:
4. If VCC falls below 2.0V, it must shut off completely before the device is turned on again.
When the Large hysteresis option is active, ICC is reduced by several hundred microamps as
well.
Security Fuse
Usage
A single fuse is provided to prevent unauthorized copying of the ATF1502AS fuse patterns.
Once programmed, fuse verify is inhibited. However, the 16-bit User Signature remains
accessible.
Programming
ATF1502AS devices are in-system programmable (ISP) devices utilizing the 4-pin JTAG pro-
tocol. This capability eliminates package handling normally required for programming and
facilitates rapid design iterations and field changes.
7
0995K–PLD–6/05
Atmel provides ISP hardware and software to allow programming of the ATF1502AS via the
PC. ISP is performed by using either a download cable, a comparable board tester or a simple
microprocessor interface.
When using the ISP hardware or software to program the ATF1502AS devices, four I/O pins
must be reserved for the JTAG interface. However, the logic features that the macrocells have
associated with these I/O pins are still available to the design for burned logic functions.
To facilitate ISP programming by the Automated Test Equipment (ATE) vendors, Serial Vector
Format (SVF) files can be created by Atmel-provided software utilities.
ATF1502AS devices can also be programmed using standard third-party programmers. With a
third-party programmer, the JTAG ISP port can be disabled, thereby allowing four additional
I/O pins to be used for logic.
Contact your local Atmel representatives or Atmel PLD applications for details.
ISP
The ATF1502AS has a special feature that locks the device and prevents the inputs and I/O
from driving if the programming process is interrupted for any reason. The inputs and I/O
default to high-Z state during such a condition. In addition, the pin-keeper option preserves the
previous state of the input and I/O PMS during programming.
Programming
Protection
All ATF1502AS devices are initially shipped in the erased state, thereby making them ready to
use for ISP.
Note:
For more information refer to the “Designing for In-System Programmability with Atmel CPLDs”
application note.
JTAG-BST/ISP
Overview
The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller in the
ATF1502AS. The boundary-scan technique involves the inclusion of a shift-register stage
(contained in a boundary-scan cell) adjacent to each component so that signals at component
boundaries can be controlled and observed using scan testing methods. Each input pin and
I/O pin has its own boundary-scan cell (BSC) to support boundary-scan testing. The
ATF1502AS does not include a Test Reset (TRST) input pin because the TAP controller is
automatically reset at power-up. The five JTAG modes supported include:
SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE and HIGHZ. The ATF1502AS’s ISP can
be fully described using JTAG’s BSDL as described in IEEE Standard 1149.1b. This allows
ATF1502AS programming to be described and implemented using any one of the third-party
development tools supporting this standard.
The ATF1502AS has the option of using four JTAG-standard I/O pins for boundary-scan test-
ing (BST) and in-system programming (ISP) purposes. The ATF1502AS is programmable
through the four JTAG pins using the IEEE standard JTAG programming protocol established
by IEEE Standard 1149.1 using 5V TTL-level programming signals from the ISP interface for
in-system programming. The JTAG feature is a programmable option. If JTAG (BST or ISP) is
not needed, then the four JTAG control pins are available as I/O pins.

ATF1502AS(L)
JTAG
The ATF1502AS contains up to 32 I/O pins and four input pins, depending on the device type
and package type selected. Each input pin and I/O pin has its own boundary-scan cell (BSC)
in order to support boundary-scan testing as described in detail by IEEE Standard 1149.1. A
typical BSC consists of three capture registers or scan registers and up to two update regis-
ters. There are two types of BSCs, one for input or I/O pin, and one for the macrocells. The
BSCs in the device are chained together through the capture registers. Input to the capture
register chain is fed in from the TDI pin while the output is directed to the TDO pin. Capture
registers are used to capture active device data signals, to shift data in and out of the device
and to load data into the update registers. Control signals are generated internally by the
JTAG TAP controller. The BSC configuration for the input and I/O pins and macrocells is
shown below.

PCI Compliance
The ATF1502AS also supports the growing need in the industry to support the new Peripheral
Component Interconnect (PCI) interface standard in PCI-based designs and specifications.
The PCI interface calls for high current drivers, which are much larger than the traditional TTL
drivers. In general, PLDs and FPGAs parallel outputs to support the high current load required
by the PCI interface. The ATF1502AS allows this without contributing to system noise while
delivering low output to output skew. Having a programmable high drive option is also possible
without increasing output delay or pin capacitance. The PCI electrical characteristics appear
on the next page.

Power-down
Mode
The ATF1502AS includes an optional pin-controlled power-down feature. When this mode is
enabled, the PD pin acts as the power-down pin. When the PD pin is high, the device supply
current is reduced to less than 5 mA. During power-down, all output data and internal logic
states are latched and held. Therefore, all registered and combinatorial output data remain
valid. Any outputs that were in a high-Z state at the onset will remain at high-Z. During
power-down, all input signals except the power-down pin are blocked. Input and I/O hold
latches remain active to ensure that pins do not float to indeterminate levels, further reducing
system power. The power-down pin feature is enabled in the logic design file. Designs using
the power-down pin may not use the PD pin logic array input. However, all other PD pin mac-
rocell resources may still be used, including the buried feedback and foldback product term
array inputs.
