A1240A-1PLG84I

Field Programmable Gate Array Overview

The A1240A-1PLG84I is an Actel ACT 2 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a CMOS process with 8,000 system gates and 1,232 Configurable Logic Blocks (CLBs). The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 75 MHz. It utilizes a 160-pin Plastic Quad Flat Package (PQFP) with an industrial temperature rating of -55°C to 125°C.

Field Programmable Gate Array Feature Summary

• High-density logic capacity utilizing antifuse technology for non-volatile configuration.

Field Programmable Gate Array Applications

• Military aerospace systems requiring extended temperature ranges.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' against official Microsemi documentation to confirm the industrial temperature grade (-55°C to 125°C) and package type. Confirm RoHS compliance status as older ACT 2 devices may not meet current environmental standards. Check for End-of-Life (EOL) or Last-Time-Buy notices from the manufacturer before procurement planning.

Field Programmable Gate Array Selection Notes

Select this component when high reliability in extreme environments is required alongside moderate logic density. Compare against the A1240A-1PLG84C if commercial temperature range suffices. Ensure design tools support the ACT 2 architecture and verify pin compatibility with existing board layouts.

Field Programmable Gate Array Part Context

This part belongs to the ACT 2 family, which succeeded the ACT 1 series. It offers higher integration than previous generations while maintaining the security and instant-on capabilities inherent to Actel's antifuse technology. It serves as a bridge between complex PLDs and early FPGAs.

Field Programmable Gate Array Replacement Considerations

Direct replacements are limited due to the discontinued status of the ACT 2 family. Consider the A1240A-1PLG84C for identical functionality with a commercial temperature range. For modern equivalents, evaluate Microsemi RTAX or SmartFusion families, though architectural differences require significant redesign.
