A42MX09-PL84A

Overview

The A42MX09-PL84A is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 14,000 system gates and 684 configurable logic blocks (CLBs). The device supports dual voltage operation with supply ranges of 3V to 3.6V and 4.75V to 5.25V. It is housed in an 84-pin PLCC package (PLCC-84, dimensions 29.31x29.31 mm) designed for surface-mount installation. The component operates within a commercial temperature range of 0°C to 70°C. It has a moisture sensitivity level (MSL) of 3 (168 hours) and complies with RoHS3 standards.

Feature Summary

• CMOS-based FPGA architecture providing non-volatile configuration capabilities
• Dual voltage support enabling compatibility with both 3.3V and 5V logic systems
• Surface-mount PLCC-84 packaging optimized for board space efficiency

Applications

• Industrial control systems requiring robust programmable logic
• Consumer electronics utilizing mixed-voltage interfaces
• Automotive infotainment and instrumentation modules

Procurement Notes

Verify the specific suffix 'A' against official Microchip documentation to confirm pinout and electrical characteristics, as suffixes often denote package or temperature variations. Confirm current availability status, as this part may be subject to discontinuation notices. Ensure compliance with RoHS3 requirements for your target market. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material changes that might affect integration.

Selection Notes

Select this component when a moderate density FPGA with 14,000 gates is required in an 84-pin PLCC form factor. It is suitable for designs needing flexibility between 3.3V and 5V power domains without external level shifters. Consider alternative packages like PQFP or TQFP if higher I/O counts or different thermal profiles are needed. Evaluate the MSL 3 rating for reflow soldering process constraints.

Part Context

This device belongs to the Actel/Microchip MX family of flash-based FPGAs, known for instant-on functionality and low power consumption. The A42MX09 variant represents a mid-range density option within this lineage, bridging the gap between lower-density A42MX02 models and higher-density A42MX16/24 devices. It retains the core architectural benefits of the series while offering a compact 84-pin footprint for cost-sensitive applications.

Replacement Considerations

Direct substitutes include other variants in the A42MX09 family such as A42MX09-PQG144 or A42MX09-FVQG100, provided the package type change is acceptable. For pin-compatible replacements, verify equivalent gate counts and I/O configurations in the same PLCC-84 package. Cross-reference with newer Microchip PolarFire or IGloo2 families for long-term supply assurance, noting significant architectural differences.
