Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'B' against official Microsemi documentation to confirm temperature grade and qualification status, as standard ACT 1 datasheets often list variants like 'C' or 'I'. Confirm current availability status, as this product line may be discontinued or subject to PCN notifications. Ensure compliance with RoHS and REACH regulations relevant to the manufacturing date code.

Field Programmable Gate Array Selection Notes

Select this component when a nonvolatile FPGA solution with moderate logic density is required for rugged environments. Compare the 69 I/O count and 547 CLB capacity against system interface requirements. Consider the PQFP package dimensions for PCB layout constraints. Verify that the 5V operating voltage aligns with the target system power rails.

Field Programmable Gate Array Part Context

This part belongs to the ACT™ 1 family, which employs silicon gate two-level metal CMOS processes. The family offers gate counts ranging from 1,200 to 20,000. The A1020 variant specifically provides a balance of logic resources and I/O flexibility suitable for complex digital control tasks in industrial and defense sectors.
