General Description

The PA7024 is a member of the Programmable Electrically Erasable Logic (PEEL?) Array family based on ICT’s CMOS EEPROM technology. PEEL? Arrays free design ers from the limitations of ordinary PLDs by providing the architectural flexibility and speed needed for today’s programmable logic designs. The PA7024 is by far the most powerful 24-pin PLD available today with 20 I/O pins, 2 input/global-clocks and 40 registers/latches (20 buried logic cells and 20 I/O registers/latches). Its logic array implements 84 sum-of-product logic functions that share 80 product terms. The PA7024’s logic and I/O cells (LCCs, IOCs) are extremely flexible, offering two output functions per logic cell (a total of 40 for all 20 logic cells). Logic cells are configurable as D, T, and JK registers with independent or global clocks, resets, presets, clock polarity, and other special features. This makes them suitable for a wide variety of combinatorial, synchronous and asynchronous logic applications. With pin compatibility and super-set function ality to most 24-pin PLDs, (22V10, EP610/630, GAL6002), the PA7024 can implement designs that exceed the architectures of such devices. The PA7024 supports speeds as fast as 10ns/15ns (tpdi/tpdx) and 71.4MHz (fMAX) at moderate power consumption 120mA (85mA typical). Packaging includes 24-pin DIP, SOIC and 28-pin PLCC (see Figure 1). Development and programming support for the PA7024 is provided by ICT and popular third-party development tool manufacturers.
