A1280A-PQ160I

Field Programmable Gate Array Overview

The A1280A-PQ160I is an ACT™ 2 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a capacity of 8000 gates and 1232 Configurable Logic Blocks (CLBs). The device supports up to 140 user I/Os and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 176-BCPGA surface-mount package with a leaded configuration. The component is designed for commercial temperature applications, functioning reliably between 0°C and 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-density digital logic replacement

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PQ160I' against official Microsemi documentation to confirm industrial temperature rating and package details. Confirm RoHS compliance status as older ACT series devices may not meet current environmental standards. Check for active obsolescence notices or last-time buy notifications from authorized distributors before procurement planning.

Field Programmable Gate Array Selection Notes

Select this part for designs requiring high gate density within the ACT family. Ensure the PCB layout accommodates the 176-pin BGA footprint. Verify that the target application environment remains within the specified commercial temperature range. Consider pin compatibility with other ACT2 devices if system scalability is required.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 2 FPGA family, which succeeded the ACT 1 series. It offers increased logic density compared to predecessors like the A1240A. The ACT 2 series was widely used for complex digital systems before being superseded by ProASIC and SmartFusion families.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the discontinuation of the ACT2 line. Review Microsemi's transition guides for migration to ProASIC3 or IGLOO2 families, noting significant architectural differences.
