GENERAL DESCRIPTION
The PALCE16V8 is an advanced PAL device built with low-power, high-speed, electrically-
erasable CMOS technology. It is functionally compatible with all 20-pin GAL devices. The
macrocells provide a universal device architecture. The PALCE16V8 will directly replace the
PAL16R8, with the exception of the PAL16C1.
The PALCE16V8Z provides zero standby power and high speed. At 30-µA maximum standby
current, the PALCE16V8Z allows battery-powered operation for an extended period.
The PALCE16V8 utilizes the familiar sum-of-products (AND/OR) architecture that allows users to
implement complex logic functions easily and efficiently. Multiple levels of combinatorial logic
can always be reduced to sum-of-products form, taking advantage of the very wide input gates
available in PAL devices. The equations are programmed into the device through floating-gate
cells in the AND logic array that can be erased electrically.
The fixed OR array allows up to eight data product terms per output for logic functions. The
sum of these products feeds the output macrocell. Each macrocell can be programmed as
registered or combinatorial with an active-high or active-low output. The output configuration
is determined by two global bits and one local bit controlling four multiplexers in each
macrocell.

FUNCTIONAL DESCRIPTION
The PALCE16V8 is a universal PAL device. The PALCE16V8Z is the zero-power version of the
PALCE16V8. It has all the architectural features of the PALCE16V8. In addition, the PALCE16V8Z
has zero standby power and an unused product term disable feature for reduced power
consumption. It has eight independently configurable macrocells (MC0-MC7). Each macrocell can
be configured as registered output, combinatorial output, combinatorial I/O or dedicated input.
The programming matrix implements a programmable AND logic array, which drives a fixed OR
logic array. Buffers for device inputs have complementary outputs to provide user-
programmable input signal polarity. Pins 1 and 11 serve either as array inputs or as clock (CLK)
and output enable (OE), respectively, for all flip-flops.
Unused input pins should be tied directly to VCC or GND. Product terms with all bits
unprogrammed (disconnected) assume the logical HIGH state, and product terms with both true
and complement of any input signal connected assume a logical LOW state.
The programmable functions on the PALCE16V8 are automatically configured from the user’s
design specification. The design specification is processed by development software to verify
the design and create a programming file (JEDEC). This file, once downloaded to a programmer,
configures the device according to the user’s desired function.
The user is given two design options with the PALCE16V8. First, it can be programmed as a
standard PAL device from the PAL16R8 series. The PAL programmer manufacturer will supply
device codes for the standard PAL device architectures to be used with the PALCE16V8.
The programmer will program the PALCE16V8 in the corresponding architecture. This allows
the user to use existing standard PAL device JEDEC files without making any changes to them.

Alternatively, the device can be programmed as a PALCE16V8. Here the user must use the
PALCE16V8 device code. This option allows full utilization of the macrocell.

CONFIGURATION OPTIONS
Each macrocell can be configured as one of the following: registered output, combinatorial
output, combinatorial I/O, or dedicated input. In the registered output configuration, the output
buffer is enabled by the OE pin. In the combinatorial configuration, the buffer is either controlled
by a product term or always enabled. In the dedicated input configuration, it is always disabled.
With the exception of MC and MC , a macrocell configured as a dedicated input derives the
0
7
input signal from an adjacent I/O. MC derives its input from pin 11 (OE) and MC from pin 1
0
7
(CLK).
The macrocell configurations are controlled by the configuration control word. It contains 2
global bits (SG0 and SG1) and 16 local bits (SL0 through SL0 and SL1 through SL1 ). SG0
0
7

determines whether registers will be allowed. SG1 determines whether the PALCE16V8 will
emulate a PAL16R8 family or a PAL10H8 family device. Within each macrocell, SL0 , in
x
conjunction with SG1, selects the configuration of the macrocell, and SL1 sets the output as
x
either active low or active high for the individual macrocell.
The configuration bits work by acting as control inputs for the multiplexers in the macrocell.
There are four multiplexers: a product term input, an enable select, an output select, and a
feedback select multiplexer. SG1 and SL0 are the control signals for all four multiplexers. In
x
MC and MC , SG0 replaces SG1 on the feedback multiplexer. This accommodates CLK being
0
7
the adjacent pin for MC and OE the adjacent pin for MC .

Registered Output Configuration
The control bit settings are SG0 = 0, SG1 = 1 and SL0 = 0. There is only one registered
x
configuration. All eight product terms are available as inputs to the OR gate. Data polarity is
determined by SL1 The flip-flop is loaded on the LOW-to-HIGH transition of CLK. The feedback
x.
path is from Q on the register. The output buffer is enabled by OE.
Combinatorial Configurations
The PALCE16V8 has three combinatorial output configurations: dedicated output in a non-
registered device, I/O in a non-registered device and I/O in a registered device.
Dedicated Output in a Non-Registered Device
The control bit settings are SG0 = 1, SG1 = 0 and SL0 = 0. All eight product terms are available
x
to the OR gate. Although the macrocell is a dedicated output, the feedback is used, with the
exception of pins 15 and 16. Pins 15 and 16 do not use feedback in this mode. Because CLK
and OE are not used in a non-registered device, pins 1 and 11 are available as input signals. Pin
1 will use the feedback path of MC , and pin 11 will use the feedback path of MC .
7
0
Combinatorial I/O in a Non-Registered Device
The control bit settings are SG0 = 1, SG1 = 1, and SL0 = 1. Only seven product terms are
x
available to the OR gate. The eighth product term is used to enable the output buffer. The signal
at the I/O pin is fed back to the AND array via the feedback multiplexer. This allows the pin to
be used as an input.
Because CLK and OE are not used in a non-registered device, pins 1 and 11 are available as
inputs. Pin 1 will use the feedback path of MC , and pin 11 will use the feedback path of MC .

0
Combinatorial I/O in a Registered Device
The control bit settings are SG0 = 0, SG1 = 1 and SL0 = 1. Only seven product terms are available
x
to the OR gate. The eighth product term is used as the output enable. The feedback signal is the
corresponding I/O signal.
Dedicated Input Configuration
The control bit settings are SG0 = 1, SG1 = 0 and SL0 = 1. The output buffer is disabled. Except
x
for MC and MC , the feedback signal is an adjacent I/O. For MC and MC , the feedback signals

Programmable Output Polarity
The polarity of each macrocell can be active-high or active-low, either to match output signal
needs or to reduce product terms. Programmable polarity allows Boolean expressions to be
written in their most compact form (true or inverted), and the output can still be of the desired
polarity. It can also save “DeMorganizing” efforts.
Selection is through a programmable bit SL1 which controls an exclusive-OR gate at the output
x
of the AND/OR logic. The output is active high if SL1 is 1 and active low if SL1 is 0.

Pow er-Up Reset
All flip-flops power up to a logic LOW for predictable system initialization. Outputs of the
PALCE16V8 will depend on whether they are selected as registered or combinatorial. If registered
is selected, the output will be HIGH. If combinatorial is selected, the output will be a function
of the logic.
Register Preload
The register on the PALCE16V8 can be preloaded from the output pins to facilitate functional
testing of complex state machine designs. This feature allows direct loading of arbitrary states,
making it unnecessary to cycle through long test vector sequences to reach a desired state. In
addition, transitions from illegal states can be verified by loading illegal states and observing
proper recovery.
Security Bit
A security bit is provided on the PALCE16V8 as a deterrent to unauthorized copying of the array
configuration patterns. Once programmed, this bit defeats readback and verification of the
programmed pattern by a device programmer, securing proprietary designs from competitors.
The bit can only be erased in conjunction with the array during an erase cycle.
Electronic Signature Word
An electronic signature word is provided in the PALCE16V8 device. It consists of 64 bits of
programmable memory that can contain user-defined data. The signature data is always available
to the user independent of the security bit.
Programming and Erasing
The PALCE16V8 can be programmed on standard logic programmers. It also may be erased to
reset a previously configured device back to its unprogrammed state. Erasure is automatically
performed by the programming hardware. No special erase operation is required.
Quality and Testability
The PALCE16V8 offers a very high level of built-in quality. The erasability of the device provides
a direct means of verifying performance of all AC and DC parameters. In addition, this verifies
complete programmability and functionality of the device to provide the highest programming
yields and post-programming functional yields in the industry.
Technology
The high-speed PALCE16V8 is fabricated with Vantis’ advanced electrically-erasable (EE) CMOS
process. The array connections are formed with proven EE cells. Inputs and outputs are
designed to be compatible with TTL devices. This technology provides strong input clamp
diodes, output slew-rate control, and a grounded substrate for clean switching.
PCI Compliance
PALCE16V8 devices in the -5/-7/-10 speed grades are fully compliant with the PCI Local Bus
Specification published by the PCI Special Interest Group. The PALCE16V8’s predictable timing
ensures compliance with the PCI AC specifications independent of the design.
Zero-Standby Pow er Mode
The PALCE16V8Z features a zero-standby power mode. When none of the inputs switch for an
extended period (typically 50 ns), the PALCE16V8Z will go into standby mode, shutting down
PALCE16V8 and PALCE16V8Z Families
7
most of its internal circuitry. The current will go to almost zero (I < 15 µA). The outputs will
CC
maintain the states held before the device went into the standby mode. There is no speed
penalty associated with coming out of standby mode.
When any input switches, the internal circuitry is fully enabled, and power consumption returns
to normal. This feature results in considerable power savings for operation at low to medium
frequencies. This saving is illustrated in the I vs. frequency graph.
CC
Product-Term Disable
On a programmed PALCE16V8Z, any product terms that are not used are disabled. Power is cut
off from the product terms so that they do not draw current. As shown in the I vs. frequency
CC
graph, product-term disabling results in considerable power savings. This saving is greater at the
higher frequencies.
Further hints on minimizing power consumption can be found in a separate document entitled,
Minimizing Power Consumption with Zero-Power PLDs.

The selected “typical” pattern utilized 50% of the device resources. Half of the macrocells were programmed as registered, and the
other half were programmed as combinatorial. Half of the available product terms were used for each macrocell. On any vector, half
of the outputs were switching.
By utilizing 50% of the device, a midpoint is defined for I . From this midpoint, a designer may scale the I graphs up or down to

ENDURANCE CHARACTERISTICS
The PALCE16V8 is manufactured using Vantis’ advanced electrically-erasable (EE) CMOS process.
This technology uses an EE cell to replace the fuse link used in bipolar parts. As a result, the
device can be erased and reprogrammed—a feature which allows 100% testing at the factory.

ROBUSTNESS FEATURES
PALCE16V8X-X/5 devices have some unique features that make them extremely robust,
especially when operating in high-speed design environments. Pull-up resistors on inputs and
I/O pins cause unconnected pins to default to a known state. Input clamping circuitry limits
negative overshoot, eliminating the possibility of false clocking caused by subsequent ringing.
A special noise filter makes the programming circuitry completely insensitive to any positive
overshoot that has a pulse width of less than about 100 ns for the /5 versions. Selected /4 devices
are also being retrofitted with these robustness features.

POWER-UP RESET
The PALCE16V8 has been designed with the capability to reset during system power-up.
Following power-up, all flip-flops will be reset to LOW. The output state will be HIGH
independent of the logic polarity. This feature provides extra flexibility to the designer and is
especially valuable in simplifying state machine initialization. A timing diagram and parameter
table are shown below. Due to the synchronous operation of the power-up reset and the wide
range of ways VCC can rise to its steady state, two conditions are required to ensure a valid
power-up reset. These conditions are:
The VCC rise must be monotonic.
Following reset, the clock input must not be driven from LOW to HIGH until all applicable input
and feedback setup times are met.

Plastic θ Considerations
jc
The data listed for plastic θ are for reference only and are not recommended for use in calculating junction temperatures. The
jc
heat-flow paths in plastic-encapsulated devices are complex, making the θ measurement relative to a specific location on the pack-
jc
age surface. Tests indicate this measurement reference point is directly below the die-attach area on the bottom center of the package.
Furthermore, θ tests on packages are performed in a constant-temperature bath, keeping the package surface at a constant tem-
jc
perature. Therefore, the measurements can only be used in a similar environment.
