A1020B-VQG80I

Field Programmable Gate Array Overview

The A1020B-VQG80I 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 input/output pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 80-pin Very Thin Quad Flat Package (VQFP) with dimensions of 14x14 mm. The component supports industrial temperature operation from -40°C to 85°C and has a Moisture Sensitivity Level (MSL) rating of 3.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing single-chip ASIC alternative capabilities
• CMOS technology for low power consumption
• Supports high-density programmable logic interconnect

Field Programmable Gate Array Applications

• Industrial control systems requiring programmable logic
• Communication interface prototyping
• Embedded system logic acceleration

Field Programmable Gate Array Procurement Notes

Verify the exact suffix against official Microsemi documentation, as the provided model lacks the speed grade digit typically present in this family (e.g., '1' or '2'). Confirm availability status, as the A1020B series was subject to discontinuation notices. Ensure compatibility with existing board footprints for the 80-VQFP package before procurement.

Field Programmable Gate Array Selection Notes

Select this component when 2000 gate density and 69 I/Os are required in a compact VQFP form factor. Compare against the A1010B series if lower gate counts suffice. Verify that the 5V supply requirement aligns with the system design. Consider the MSL 3 rating for reflow soldering process planning.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 1 FPGA family, which bridges the gap between complex PLDs and full-scale FPGAs. The A1020B variant specifically offers higher density than the A1010B. The VQG80 suffix denotes the 80-pin VQFP package with industrial temperature range. This family was widely used for mid-range logic applications before newer architectures became available.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. The A1020B series has been discontinued; consult Microsemi for current generation equivalents or authorized cross-reference databases.
