A1240A-PQ144C

Field Programmable Gate Array Overview

The A1240A-PQ144C is a Field Programmable Gate Array (FPGA) from the Microsemi ACT2 family, manufactured using CMOS technology. It features an organization of 1232 Configurable Logic Blocks (CLBs) and approximately 8000 equivalent gates. The device supports a maximum operating frequency of 70 MHz and operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. It is housed in a PQFP-144 package containing 144 terminals. The component is designated for commercial temperature ranges.

Field Programmable Gate Array Feature Summary

• ACT2 antifuse architecture providing non-volatile configuration without external memory requirements.
• High-density logic capacity replacing up to 200 TTL packages or eighty 20-pin PAL packages.
• Integrated design library featuring over 500 macro functions for rapid development.

Field Programmable Gate Array Applications

• Complex digital logic integration in industrial control systems.
• Replacement for legacy discrete TTL and PAL logic circuits.
• Custom interface adapters and protocol converters.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PQ144C' against official Microsemi documentation to confirm the package type and temperature grade. Confirm current lifecycle status as these older ACT2 devices may be End-of-Life or available only through life-buy programs. Ensure compatibility with existing 5V power rails and programming equipment before procurement.

Field Programmable Gate Array Selection Notes

Select this model when a moderate gate count with high-speed performance is required in a surface-mount package. Compare against the A1240A-VQ144C if a smaller footprint is needed, or the A1240A-PG132C for different pin counts. Verify that the 70 MHz speed grade meets the system timing requirements compared to faster -1 speed grades.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT2 family, which utilizes proprietary antifuse technology for permanent configuration. The ACT2 series was designed to offer high performance and density while simplifying board design by eliminating the need for configuration PROMs. It serves as a bridge between standard PLDs and larger FPGAs.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same family include the A1240A-VQ144C (VQFP package) or A1240A-PG132C (different pin count). Cross-family migration to ProASIC3 or IGLOO requires schematic redesign due to architectural differences.
