General Description

The PA7572 is a member of the Programmable Electrically Erasable Logic (PEEL?) Array family based on Anachip’s CMOS EEPROM technology. PEEL? Arrays free designers from the limitations of ordinary PLDs by providing the architectural flexibility and speed needed for today’s programmable logic designs. The PA7572 offers a versatile logic array architecture with 24 I/O pins, 14 input pins and 60 registers/latches (24 buried logic cells, 12 input registers/latches, 24 buried I/O registers/latches). Its logic array implements 100 sum-of-products logic functions divided into two groups each serving 12 logic cells. Each group shares half (60) of the 120 product-terms available.
