Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm voltage grade and temperature rating. Confirm RoHS compliance status as some variants may differ. Check for active manufacturing status and lead times directly with authorized distributors. Ensure ESD handling procedures are followed during procurement and storage.

Selection Notes

Select this model for designs requiring deterministic timing and high pin-fixing capabilities. Compare gate counts and I/O availability against A40MX02 or A42MX series devices if different capacity is needed. Verify package compatibility with PCB footprint requirements for PLCC-84. Consider power consumption profiles relative to system thermal constraints.

Part Context

This component belongs to the Actel MX family of FPGAs, now part of Microchip Technology. The MX series is known for non-volatile flash-based technology, eliminating the need for external configuration memory. This specific part offers a mid-range gate count suitable for complex logic replacement in embedded systems.

Replacement Considerations

Direct pin-to-pin replacements within the same package and functionality are limited due to specific feature sets. Review A40MX04 variants with different speed grades or packages. Cross-reference with A42MX series for updated feature sets, though pinouts may differ.
