A1240A-PL84I

Field Programmable Gate Array Overview

The A1240A-PL84I is an ACT 2 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a CMOS technology 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 up to 75 MHz performance. It is housed in an 84-pin PLCC package with 69 user I/Os. The component is designated as End-of-Life (EOL) or Lifebuy status.

Field Programmable Gate Array Feature Summary

• High-density logic capacity with 8,000 gates and 1,232 CLBs for complex digital designs
• Single-chip ASIC alternative capability replacing multiple TTL and PAL packages
• Supports wide-input combinatorial functions and single-module sequence operations

Field Programmable Gate Array Applications

• Complex digital logic replacement for legacy TTL and PAL systems
• System integration requiring high pin counts and dense logic resources
• Prototyping and low-volume production of custom digital circuits

Field Programmable Gate Array Procurement Notes

This component is officially classified as End-of-Life (EOL) or Lifebuy by the manufacturer. Procurement should be verified through authorized distributors or Microsemi directly. Availability is limited to existing stock or last-time buy orders. Verify the specific suffix 'I' indicates industrial temperature rating and ensure compatibility with existing board layouts before ordering.

Field Programmable Gate Array Selection Notes

Select this part when designing systems requiring 8,000 equivalent gates and 1,232 CLBs in an 84-pin PLCC package. Ensure the design environment supports the ACT 2 architecture and that the 4.5V to 5.5V supply voltage aligns with system power rails. Consider the EOL status for long-term production viability and evaluate migration paths if future scalability is required.

Field Programmable Gate Array Part Context

The A1240A-PL84I belongs to the Microsemi ACT 2 FPGA family, which utilizes antifuse technology. This series was designed to replace large numbers of discrete logic components. The 'PL84' suffix denotes the Plastic Leadless Chip Carrier package with 84 pins. The 'I' suffix typically specifies the industrial temperature range operation.

Field Programmable Gate Array Replacement Considerations

As an EOL product, direct replacements are not available from the same family. Evaluate modern Microsemi RTAX or SmartFusion families for functional equivalents. Check pinout compatibility and logic density requirements when selecting alternative FPGAs from other manufacturers.
