Field Programmable Gate Array Procurement Notes

This component has been officially declared obsolete by the manufacturer as of June 21, 2013. Verification of authenticity is critical due to potential availability through third-party channels. Buyers must confirm the specific suffix 'C' denotes the commercial temperature grade and verify the package integrity upon receipt. Supply chain sources should be audited for compliance with export regulations and moisture sensitivity handling requirements.

Field Programmable Gate Array Selection Notes

Engineers selecting this part should note its discontinuation status and evaluate long-term sustainability. The 84-PLCC package requires specific footprint design considerations compared to modern QFP or BGA options. Designers must ensure that the 4.5V to 5.5V supply range aligns with existing system power rails. Alternative solutions from newer Microsemi families may offer pin-compatible upgrades but require schematic review.

Field Programmable Gate Array Part Context

The A1020B-1PLG68C belongs to the ACT™ 1 family, which utilizes flash technology for instant-on configuration without external memory. This series was designed for high-reliability applications requiring low power consumption and fast programming cycles. The 'A1020' base model indicates a mid-range density within the ACT™ 1 portfolio, balancing gate count with pin availability for versatile integration.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The entire A1010B and A1020B product line was discontinued on June 21, 2013. Engineers should consult Microchip Technology for current generation FPGA equivalents that match the required logic density and I/O count.
