FUNCTIONAL DESCRIPTION
The PALLV16V8 is a low-voltage, EE CMOS version of the PALCE16V8.
The PALLV16V8Z is a low-voltage, EE CMOS version of the PALCE16V8. In addition, the
PALLV16V8Z has zero standby power and an unused product term disable feature for reduced
power consumption.
The PALLV16V8 is a universal PAL device. It has eight independently configurable macrocells
(MC
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 V
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 PALLV16V8 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. This file, once downloaded to a programmer, configures the
device according to the user’s desired function.
