A1020B-1PL68C

Field Programmable Gate Array Overview

The A1020B-1PL68C is an ACT™ 1 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 2000 system gates and 547 Configurable Logic Blocks (CLBs). The device provides 57 user-programmable I/O pins and is housed in a 68-pin PLCC package with J-leads. It operates on a supply voltage of 4.5V to 5.5V and supports surface mount installation. The component is rated for an industrial operating temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-capacity single-chip ASIC alternative capabilities
• Supports mixed-voltage operation for core and I/Os
• Includes up to 2.5 kbits of configurable dual-port SRAM

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic timing
• Automotive electronics applications
• Mixed-signal interface bridging

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1PL68C' against official Microsemi documentation to confirm the commercial temperature grade and package type, as suffixes define environmental ratings. Confirm end-of-life status via manufacturer PCN notices, as the A1020B family has been subject to discontinuation announcements. Ensure compatibility with existing PCB footprints for 68-PLCC packages during sourcing.

Field Programmable Gate Array Selection Notes

Select this part when 2000 gates and 57 I/Os are sufficient for the design logic density. Compare against the A1010B variant if lower gate counts are acceptable. Verify that the 68-pin PLCC package fits the assembly constraints compared to QFP or LCC alternatives within the same family. Check if the 0°C to 70°C temperature range meets the final application environment requirements.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 FPGA family, designed as a high-capacity alternative to ASICs. The A1020B model specifically offers 2000 gates, distinguishing it from the smaller A1010B. The family emphasizes ease of integration with mixed-voltage support and diagnostic capabilities via Silicon Explorer II tools.

Field Programmable Gate Array Replacement Considerations

The A1020B-2PL68C is a verified substitute offering identical electrical characteristics but rated for the industrial temperature range (-40°C to 85°C). Other pin-compatible options include the A1020B-1PLG68C and A1020B-PLG68I, which share the same gate count and I/O configuration.
