It provides 140 user Input/Output pins and operates within a supply voltage range of 4.5V to 5.5V. The device is housed in a 176-pin Plastic Grid Array (PG) package, specifically identified as 176-BCPGA. It supports a maximum operating frequency of 75 MHz with a typical CLB combinatorial delay of 4.3 ns. The component is rated for commercial temperature operation ranging from 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 2 architecture utilizing PLICE antifuse technology for non-volatile configuration.

Field Programmable Gate Array Applications

• High-speed digital signal processing systems.

Field Programmable Gate Array Part Context

This component is part of the Microsemi ACT™ 2 FPGA family, which succeeded the ACT™ 1 series. The ACT™ 2 devices were designed to replace multiple TTL packages and offer higher density logic resources compared to earlier generations. The manufacturer has since been acquired by Microchip Technology, affecting long-term support channels for this legacy product line.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the device is marked End-of-Life, engineering change orders should verify pinout compatibility and timing requirements against alternative FPGA families before implementation.
