A1020B-1PLG44C

Field Programmable Gate Array Overview

The A1020B-1PLG44C is an ACT™ 1 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a logic density of 2000 equivalent gates organized into 547 Configurable Logic Blocks (CLBs). The device provides 34 user-accessible I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 44-pin PLCC package with J-leads, measuring 16.59x16.59 mm. The component supports surface mount installation and functions reliably across an operating temperature range of 0°C to 70°C.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature grade (0°C to 70°C) versus industrial variants. Confirm the package type is 44-LCC(J) as listed. Note that this part number is officially marked as obsolete or end-of-life by the manufacturer. Ensure compatibility with existing PCB footprints for 44-PLCC packages before procurement planning.

Field Programmable Gate Array Selection Notes

Select this model when 2000 gate density and 34 I/Os are required in a compact 44-pin form factor. Compare against other ACT™ 1 variants like the A1020A series if different speed grades or temperature ranges are needed. Ensure the design tool suite supports the legacy ACT™ 1 family for programming and verification.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 FPGA family, designed as a drop-in replacement for complex standard logic and small ASICs. The A1020B variant specifically denotes the 2000-gate density tier within the ACT™ 1 lineup, offering a balance of logic capacity and pin count for embedded control and data path applications.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, consider modern Microsemi SmartFusion or IGLOO families for new designs, though these require schematic and layout redesign.
