A40MX04-1PLG84

Overview

The A40MX04-1PLG84 is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 547 configurable logic blocks and approximately 6000 system gates. The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It offers up to 69 user-programmable I/O pins and operates within a commercial temperature range of 0°C to 70°C. The component is housed in a 84-pin plastic leaded chip carrier package.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, compatible with 5.0V or 3.3V systems.
• Features fast wide-decode circuitry and deterministic, user-controllable timing.
• Provides up to 100% resource utilization and 100% pin locking capabilities.

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage interface bridging between 3.3V and 5V domains
• Complex logic control in industrial automation systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for recent product change notifications regarding manufacturing sites or software updates. Ensure compatibility with existing PCB footprints for the 84-pin PLCC package.

Selection Notes

Select this model for applications requiring moderate logic density with mixed-voltage I/O support. Compare against other MX family members if higher gate counts or different package options are needed. Verify that the 0°C to 70°C operating range meets environmental requirements. Consider pin count limitations relative to the 84-pin package size.

Part Context

This part belongs to the A40MX04 series within the broader MX FPGA family. It shares architectural similarities with variants like the A40MX04-1PLG68 and A40MX04-3PLG84I but differs in package and I/O count. The family is known for non-volatile flash-based technology, eliminating the need for external configuration memory.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages, such as A40MX04-1PLG68 or A40MX04-2PLG44, provided pin compatibility is verified. Cross-family replacements may require significant design changes due to architecture differences.
