Field Programmable Gate Array Procurement Notes

Verify current availability status as this part number is listed as obsolete by the manufacturer. Confirm that the specific suffix indicates the intended package type and temperature grade. Ensure compatibility with existing board layouts due to the fixed 80-VQFP footprint. Check for any last-time buy notifications or recommended alternative components from Microchip Technology before finalizing procurement plans.

Field Programmable Gate Array Selection Notes

Select this component when a moderate gate count FPGA with non-volatile configuration is required. The ACT™ 1 series is suitable for designs needing immediate power-up functionality without external configuration flash. Consider the 80-pin VQFP package constraints for PCB space limitations. Evaluate if the 2000-gate density meets the specific logic requirements of the target application.

Field Programmable Gate Array Part Context

This device belongs to the Microsemi ACT™ 1 family, which represents an early generation of non-volatile FPGAs. These parts were designed to simplify system design by eliminating the need for separate configuration memory devices. The A1020B variant specifically offers a balance of logic resources and I/O flexibility within the 80-pin form factor.

Field Programmable Gate Array Replacement Considerations

Microchip issued a Product Change Notification for the A1010B and A1020B series on June 21, 2013. Verify if newer generations such as the SmartFusion or IGLOO families are suitable replacements, noting significant architectural differences.
