Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1VQG100C' against official Microsemi documentation to confirm the exact speed grade and commercial temperature range. Confirm RoHS compliance status as earlier ACT3 variants may not meet current environmental standards. Check for active production status or obsolescence notices prior to procurement planning.

Field Programmable Gate Array Selection Notes

Select this model when a moderate gate count of 2,500 is sufficient for complex logic functions without the need for embedded memory blocks. Ensure the design requires a 5V core voltage compatible with legacy systems. Verify that the 100-pin TQFP package fits the available PCB real estate and thermal constraints for commercial environments.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT3 family, designed as a cost-effective alternative to Application-Specific Integrated Circuits (ASICs). The ACT3 series utilizes CMOS technology to deliver high performance with low power consumption. It serves as a bridge between simple PLDs and larger FPGAs, offering a balance of flexibility and integration for mid-complexity digital designs.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other ACT3 devices such as the A1425A-PQG100I or A1425A-1CQ132C, provided pinout and electrical specifications match. Cross-family migration to ProASIC or SmartFusion may require significant schematic and firmware redesign due to architectural differences.
