A1020B-PL84C

Field Programmable Gate Array Overview

The A1020B-PL84C 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 Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 29.31x29.31 mm. The component supports surface mount installation and functions reliably across an ambient temperature range of 0°C to 70°C.

Field Programmable Gate Array Procurement Notes

This specific part number is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or approved obsolescence management programs. Sourcing should prioritize verified suppliers to ensure component authenticity and traceability given the end-of-life status.

Field Programmable Gate Array Selection Notes

Select this component when a 2000-gate FPGA solution with 69 I/Os is required in an 84-pin PLCC package. Ensure the design environment supports the ACT™ 1 family tools. Verify that the commercial temperature range (0°C to 70°C) meets the operational requirements, as industrial variants may require different suffixes.

Field Programmable Gate Array Part Context

The A1020B-PL84C belongs to the Microsemi ACT™ 1 family, a legacy line of CMOS FPGAs. This series was widely used for replacing complex discrete logic and implementing custom digital functions before the dominance of modern high-capacity architectures. It shares core specifications with other A1020B variants differing primarily in package type and speed grade.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to the obsolete status. Designers should evaluate modern FPGA families from Microsemi (Microchip) or other vendors, utilizing translation tools if available. Alternative packages such as QFP or BGA may be necessary depending on board layout constraints.
