A1240A-1PLG84C

Field Programmable Gate Array Overview

The A1240A-1PLG84C is an ACT 2 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a CMOS process with 1232 Configurable Logic Blocks (CLBs) and 8000 equivalent gates. The device operates within a supply voltage range of 4.5V to 5.5V, typically rated at 5V. It utilizes a 176-pin Ceramic Plastic Grid Array (CPGA) package with a grid spacing of 2.54 mm. The component supports a maximum operating frequency of 75 MHz and is designed for military temperature ranges from -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 high reliability and radiation tolerance.

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Confirm RoHS compliance status as older ACT 2 devices may not meet current environmental standards. Check for End-of-Life or Last-Time-Buy notifications from the manufacturer before procurement planning.

Field Programmable Gate Array Selection Notes

Select this model when a high gate count FPGA with military-grade temperature specifications is required. Ensure the design accommodates the 176-pin CPGA footprint and 5V I/O requirements. Consider pin compatibility if replacing legacy ACT 2 designs.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT 2 family, which succeeded the ACT 1 series. It offers significantly higher logic density compared to earlier generations while maintaining the fast, deterministic performance characteristic of antifuse-based FPGAs.

Field Programmable Gate Array Replacement Considerations

Direct replacements are limited due to the discontinued status. Evaluate ACT 3 family members like the A1440A for higher density or similar pin-count alternatives if available in current production.
