Description

USE GAL DEVICES FORNEW DESIGNS The PALLV22V10 is an advanced PAL ® device built with low-voltage, high-speed, electricallyerasable CMOS technology.

The PALLV22V10Z provides low voltage and zero standby power. At 30 µA maximum standby current, the PALLV22V10Z allows battery powered operation for an extended period.

The PALLV22V10 device implements the familiar Boolean logic transfer function, the sum of products. The PAL device is a programmable AND array driving a fixed OR array. The AND array is programmed to create custom product terms, while the OR array sums selected terms at the outputs.

PALLV22V10 terms are connected to the fixed OR array with a varied distribution from 8 to 16 across the outputs (see Block Diagram). The OR sum of the products feeds the output macrocell. Each macrocell of PALLV22V10 can be programmed as registered or combinatorial, and active high or active low. The output configuration is determined by two bits controlling two multiplexers in each macrocell.
