Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity and lead condition prior to assembly. Check for moisture sensitivity level compliance during storage handling. Ensure design files are compatible with legacy programming tools associated with the ACT™ 1 family.

Field Programmable Gate Array Selection Notes

Select this component when specific ACT™ 1 architecture compatibility is required. Consider pin count and gate density requirements against available alternatives. Evaluate thermal management needs for the CQFP package in the target application environment. Review toolchain support availability for older FPGA families before finalizing the design choice.

Field Programmable Gate Array Part Context

This part belongs to the ACT™ 1 series of FPGAs, representing early generation programmable logic technology. The series was designed to offer flexibility for complex digital designs using anti-fuse or SRAM-based technologies depending on the variant. It serves as a foundational component for legacy systems requiring reprogrammable hardware logic.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitute part numbers are not available. The A1010B and A1020B series have been officially discontinued. Designers must evaluate migration paths to modern FPGA architectures or maintain existing inventory for replacement purposes.
