Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a specific moisture sensitivity level, lead-free status, or packaging variant distinct from the standard 'I' or un-suffixed versions. Ensure the ordering part number matches the exact package type and temperature grade required for your design. Cross-reference with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this model when a balance of gate density and low power consumption is required for mid-complexity designs. Compare the 69 I/O count against interface requirements to ensure sufficient pin availability. Consider the VQFP-80 package constraints regarding PCB space and thermal dissipation. Evaluate the 48.24 MHz speed grade against timing closure needs for synchronous logic paths.

Part Context

This component belongs to the Actel/Microchip MX series of SRAM FPGAs, known for their low power consumption and ease of use compared to larger FPGA families. The A40MX04 represents a specific gate count tier within this lineage, offering a cost-effective solution for replacing complex discrete logic or CPLDs. It shares architectural similarities with other MX devices but differs in resource size and I/O capacity.

Replacement Considerations

Direct replacements include other variants within the A40MX04 family such as A40MX04-1VQG80I for industrial temperature grades. For higher density needs, consider the A40MX08 series. Verify pin-to-pin compatibility and software toolchain support before substituting.
