A1020B-1PL44C

Field Programmable Gate Array Overview

The A1020B-1PL44C is an ACT™ 1 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 547 Configurable Logic Blocks (CLBs) and approximately 2000 equivalent gates. The device operates within a supply voltage range of 4.5V to 5.5V and supports up to 34 I/O pins. It is housed in a 44-pin PLCC package with J-leads, measuring 16.59x16.59 mm. The component is rated for commercial temperature operation from 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-density logic resources in a compact form factor
• CMOS technology enabling low power consumption and high-speed performance
• Supports full pin locking and 100% resource utilization for deterministic design implementation

Field Programmable Gate Array Applications

• High-capacity single-chip ASIC replacement
• Complex digital logic prototyping
• Custom interface bridging in embedded systems

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1' indicates the speed grade and 'PL44' denotes the package type against official Microsemi documentation. Confirm end-of-life status and last-time-buy dates prior to procurement planning. Ensure compatibility with existing PCB footprints for 44-LCC packages.

Field Programmable Gate Array Selection Notes

Select this model when 547 CLBs are required in a 44-pin surface-mount package. Compare against A1020A variants if industrial temperature ranges (-40°C to 85°C) are necessary instead of the commercial range. Verify that the 4.5V-5.5V supply requirement aligns with system power rails.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 1 family, designed as a drop-in replacement for complex PALs and GALs. It offers non-volatile configuration using Flash memory technology, eliminating the need for external configuration PROMs common in earlier FPGA generations.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements may include A1020A-1PL44C, though temperature ratings differ. Cross-reference with A1020 series derivatives for similar gate counts. No active direct substitutes exist; consider migration to modern Microsemi SmartFusion or IGLOO families for new designs.
