Field Programmable Gate Array Procurement Notes

Verify part authenticity through authorized channels as this component is listed as obsolete by the manufacturer. Confirm specific suffix requirements against original design specifications to ensure pin compatibility. Request detailed datasheets to validate electrical characteristics before integration into new production runs.

Field Programmable Gate Array Selection Notes

Select this model when a 2000-gate FPGA solution is required in an 84-pin PLCC package. Ensure the design environment supports the ACT™ 1 toolchain. Verify that the 0°C to 70°C commercial temperature range meets the operational requirements of the target application.

Field Programmable Gate Array Part Context

This component is part of the Microsemi ACT™ 1 family, which represents an earlier generation of FPGAs. It serves as a bridge between discrete logic solutions and modern high-density programmable devices. The ACT™ 1 series was widely used in the late 1990s and early 2000s for various embedded applications.

Field Programmable Gate Array Replacement Considerations

Microchip has officially discontinued the A1020B series. Designers should evaluate modern FPGA families from Microsemi or other vendors for long-term supply stability. Pin-compatible replacements may be limited due to architectural differences.
