Field Programmable Gate Array Procurement Notes

Verify the suffix 'I' confirms the industrial temperature grade (-40°C to 100°C TJ). Confirm the package designation matches the 100-lead Very Thin Quad Flat Package dimensions. Ensure the specific revision level aligns with design tool compatibility. Cross-reference the manufacturer part number against official Microchip databases to confirm current production status and RoHS compliance before finalizing procurement orders.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile configuration is required to reduce board space and BOM cost. Choose the industrial grade variant if the application environment exceeds commercial temperature limits. Verify that the 71 available I/O pins meet the interface requirements. Compare the 125,000 gate count against logic complexity needs to ensure sufficient resources for the target design implementation.

Field Programmable Gate Array Part Context

This model belongs to the ProASIC3 Flash family, which bridges the gap between ASICs and traditional SRAM-based FPGAs. Unlike volatile counterparts, this series retains configuration data without power. The VQG100I variant specifically targets applications needing robust performance in harsh environments while maintaining low standby power consumption typical of flash-based architectures.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same family include other A3P125 variants with different speed grades or temperature ratings. Consider the A3PN125 series for nano-density alternatives if gate counts allow. Verify that any substitute maintains the 100-VQFP footprint and compatible voltage specifications.
