• Robust electrostatic discharge (ESD) protection meeting stringent industrial standards
• Flexible I/O architecture supporting multiple voltage standards and signaling types

Applications

• Industrial control systems requiring reliable field programmable gate arrays
• Consumer electronics needing low-power, instant-on functionality
• Automotive infotainment and instrumentation modules
• Telecommunications equipment interface cards

Procurement Notes

Verify the specific suffix codes on the component marking against official Microchip documentation to confirm temperature grade, package type, and lead-free status. Ensure compatibility with your design's voltage requirements and pinout constraints before procurement. Cross-reference the full part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when instant-on capability and moderate logic density are required without external configuration memory. Evaluate the available I/O count against your interface needs. Consider the operating frequency limits and power consumption profiles relative to your thermal design. Verify that the PQFP-100 package fits your PCB layout constraints.

Part Context

This component belongs to the MachXO series, designed for cost-sensitive applications replacing complex logic or small CPLDs. It bridges the gap between standard CPLDs and higher-end FPGAs by offering Flash-based reprogrammability with lower power consumption. The series is widely used in legacy system upgrades and new designs prioritizing simplicity and reliability.

Replacement Considerations

Direct replacements may include other MachXO variants with similar gate counts or I/O configurations. Check datasheets for pin-to-pin compatibility and electrical parameter equivalence. Alternative families require careful review of configuration methods and I/O voltage levels.
