Field Programmable Gate Array Procurement Notes

Verify the exact suffix against official Microsemi documentation, as variations exist between CQFP and PLCC packages. Confirm that the specific speed grade matches system timing requirements. Check current availability status, as this component may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints before procurement.

Field Programmable Gate Array Selection Notes

Select this part when a low-gate-count FPGA with parallel I/O is required. Compare pin counts against other ACT™ 1 variants like the A1010B if fewer resources suffice. Verify that the 84-pin form factor fits the mechanical constraints. Consider thermal performance within the specified operating range during selection.

Field Programmable Gate Array Part Context

This component belongs to the ACT™ 1 family, representing early generation FPGAs from Actel and later Microsemi. These devices were widely used in aerospace and industrial applications requiring radiation tolerance and non-volatile configuration. The A1020B variant offers a balance of density and pin count for moderate complexity designs.

Field Programmable Gate Array Replacement Considerations
