A1020B-1PL84I

Field Programmable Gate Array Overview

The A1020B-1PL84I is an ACT™ 1 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a logic capacity of 2000 equivalent gates organized into 547 Configurable Logic Blocks (CLBs). The device provides 69 user-accessible I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-pin PLCC package with J-leads, specifically identified as 84-LCC(J). The component supports surface mount installation and is rated for commercial operating temperatures between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• CMOS technology enabling operation at standard 5V supply levels
• 84-pin plastic leaded chip carrier package suitable for surface mount applications

Field Programmable Gate Array Applications

• General-purpose digital logic prototyping
• Interface bridging between different logic families
• Custom state machine implementation

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' against official Microsemi documentation to confirm industrial temperature rating requirements. Confirm package type accuracy as sources vary between PLCC and LCC designations. Check current availability status as this part number may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints before procurement.

Field Programmable Gate Array Selection Notes

Select this model when 2000 gate density and 69 I/Os are required in an 84-pin form factor. Compare against the A1020B-1PLG84C if commercial temperature range suffices. Verify that the 4.5V to 5.5V supply requirement aligns with system power rails. Consider pin count limitations for designs requiring more external connections.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, a legacy line of CMOS FPGAs. It shares core logic resources with variants like the A1020B-1PLG84C but differs in package style and temperature grade. The family was designed for ASIC prototyping and low-volume production before transitioning to flash-based technologies.
