A1020B-2PLG84C

Field Programmable Gate Array Overview

The A1020B-2PLG84C is an ACT™ 1 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 547 Configurable Logic Blocks (CLBs) and approximately 2000 system gates, housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads. The device operates on a single 5V supply voltage within the range of 4.5V to 5.5V. It provides 57 general-purpose I/O pins and supports surface-mount installation. The component is rated for commercial temperature operation between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-density logic resources in a compact form factor
• Single 5V power supply requirement simplifying board design
• Plastic PLCC packaging suitable for standard surface-mount assembly processes

Field Programmable Gate Array Applications

• General-purpose digital logic prototyping
• Interface bridging between different voltage domains or protocols
• Custom state machine implementation in embedded systems

Field Programmable Gate Array Procurement Notes

This specific part number is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on distributor surplus stock or certified second-source alternatives rather than direct new production orders. Buyers must confirm the manufacturing date code and physical condition upon receipt, as these are legacy components no longer actively produced.

Field Programmable Gate Array Selection Notes

Engineers selecting this FPGA should consider its 547 CLB capacity and 57 I/O count relative to their logic density requirements. The fixed 5V operating voltage limits compatibility with modern low-voltage core designs without level shifting. Designers must account for the plastic PLCC package thermal characteristics and ensure PCB layout supports the specific lead pitch and footprint dimensions defined in the official datasheet.

Field Programmable Gate Array Part Context

The A1020B-2PLG84C belongs to the Microsemi ACT™ 1 family, which was designed as a high-capacity alternative to complex ASICs during its active production period. This series utilized CMOS technology to offer reprogrammability with performance comparable to fixed logic. The '2' suffix typically denotes a specific speed grade within the A1020B product line, distinguishing it from slower variants like the A1020B-1.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are not available due to the component's obsolete status. Engineers should evaluate newer Microsemi SmartFusion or IGLOO families for functional equivalents, though these require schematic and layout redesigns. Alternative sources may include verified surplus inventory from authorized distributors.
