A1240A-PG132B

Field Programmable Gate Array Overview

The A1240A-PG132B is a Field Programmable Gate Array (FPGA) from the ACT 2 family, manufactured by Microsemi Corporation. It features 684 Configurable Logic Blocks (CLBs) and an equivalent capacity of 4000 gates. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. It utilizes CMOS technology and is housed in a ceramic PGA-132 package with a grid array configuration. The component supports a maximum operating temperature of 70 °C and a minimum of -55 °C, indicating suitability for industrial or military environments.

Field Programmable Gate Array Feature Summary

• Utilizes antifuse-based FPGA architecture for non-volatile configuration.

Field Programmable Gate Array Applications

• High-reliability aerospace systems
• Military communication equipment
• Industrial control logic

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'B' against official Microsemi documentation to confirm pinout and electrical characteristics, as variations exist within the ACT 2 family. Confirm RoHS compliance status, as older ceramic packages may differ from modern standards. Check for End-of-Life (EOL) or Last-Time-Buy notices, as this series has been superseded by newer generations. Ensure sourcing channels provide traceability for military-grade specifications if required.

Field Programmable Gate Array Selection Notes

Select this component when a robust, radiation-tolerant FPGA solution is needed for legacy system maintenance. Compare against the A1240XL series for updated performance metrics if new designs are considered. Verify that the 132-pin PGA footprint matches the target PCB layout constraints. Consider the 4000-gate density sufficient for moderate complexity state machines and interface logic.

Field Programmable Gate Array Part Context

This part belongs to the ACT 2 family, which was designed to replace complex discrete TTL logic. It serves as a high-density programmable logic alternative for applications requiring reconfigurability without the volatility of SRAM-based FPGAs. The family is known for its security due to the one-time programmable antifuse technology.

Field Programmable Gate Array Replacement Considerations

Direct replacements are limited due to the discontinuation of the ACT 2 line. Potential alternatives include the A1240XL series for similar gate counts or the RTAX/SX families for radiation-hardened requirements. Consult Microsemi (now Microchip) for current cross-reference guides.
