A1020B-2PQ100I

Field Programmable Gate Array Overview

The A1020B-2PQ100I is an embedded Field Programmable Gate Array (FPGA) belonging to the Microsemi ACT™ 1 series. It features a logic capacity of 2000 gates and includes 547 Logic Array Blocks (LABs). The device provides 80 input/output pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 100-pin Plastic Quad Flat Package (PQFP) with dimensions of 20x14 mm. The component supports an industrial operating temperature range from -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• Supports high-density logic implementation using 547 LABs for complex digital designs.
• Features mixed-voltage I/O capability allowing operation with both 5.0V and 3.3V peripherals.
• Provides deterministic timing characteristics suitable for synchronous system integration.

Field Programmable Gate Array Applications

• Industrial control systems requiring robust logic processing.
• Communication interface adapters and protocol converters.
• Automotive electronic control units (ECUs).

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '2' indicates the industrial temperature grade (-40°C to +85°C) rather than commercial grade. Confirm package integrity upon receipt, as PQFP leads are susceptible to bending during transit. Ensure static-safe handling procedures are followed due to CMOS technology sensitivity. Cross-reference the manufacturer part number against official Microchip archives to confirm current availability status.

Field Programmable Gate Array Selection Notes

Select this model when 2000 gate capacity and 80 I/Os are required for space-constrained applications. The PQFP-100 package offers a balance between pin count and board area. Compare against the A1020B-1PQ100I if only commercial temperature range is needed. Consider the ACT™ 1 architecture constraints regarding routing resources and clock distribution networks before finalizing the design.

Field Programmable Gate Array Part Context

This component is part of the Microsemi ACT™ 1 family, which succeeded earlier CPLD technologies. It serves as a bridge between simple programmable logic and larger FPGAs. The A1020 variant specifically targets mid-range complexity applications. The '2' suffix denotes the extended industrial temperature rating compared to the standard commercial version.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Designers should evaluate the A1020B-1PQ100I for non-industrial applications or consult Microchip for legacy replacement programs.
