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 congurable macrocells (MC0-MC7). Each macrocell can
be congured as registered output, combinatorial output, combinatorial I/O or dedicated input.
The programming matrix implements a programmable AND logic array, which drives a xed 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 ip-ops.
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 congured from the user’s
design specication. The design specication is processed by development software to verify
the design and create a programming le (JEDEC). This le, once downloaded to a programmer,
congures 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 les without making any changes to them.
