A1020B-PLG84C

Field Programmable Gate Array Overview

The A1020B-PLG84C is an embedded Field Programmable Gate Array (FPGA) IC from the Microsemi ACT™ 1 series. It features 547 Configurable Logic Blocks (CLBs) and approximately 2000 equivalent gates. The device provides 69 I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-LCC (J-lead) surface-mount package, specifically identified as 84-PLCC with dimensions of 29.31x29.31 mm. The component supports an industrial operating temperature range of -40°C to 85°C.

Field Programmable Gate Array Feature Summary

Field Programmable Gate Array Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or qualified second-source alternatives. Ensure any sourced units match the original ACT™ 1 specifications and package integrity before integration into production designs.

Field Programmable Gate Array Selection Notes

Select this part when specific ACT™ 1 architecture compatibility is required for legacy designs. The 84-pin LCC package offers a balance of I/O count and board space. Verify that the design does not require higher gate counts found in the A10K series or different voltage domains.

Field Programmable Gate Array Part Context

The A1020B-PLG84C belongs to the Microsemi ACT™ 1 family, which was succeeded by the SmartFusion and IGLOO series. This specific model represents a mid-range density option within the legacy portfolio, designed for applications where established ACT architecture stability is preferred over newer high-density capabilities.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip's official obsolescence notices for recommended migration paths to modern FPGA families.
