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-碌A(chǔ) 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 ef鏗乧iently. 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 鏗俹ating-gate
cells in the AND logic array that can be erased electrically.
The 鏗亁ed 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 con鏗乬uration
is determined by two global bits and one local bit controlling four multiplexers in each
macrocell.
