Procurement Notes

Verify the specific ordering suffix against official NXP documentation to ensure correct package type, temperature grade, and tape-and-reel specifications. Confirm that the requested part number matches the exact pinout and memory configuration required for your design. Cross-reference with authorized distributors to validate authenticity and current manufacturing status before finalizing procurement orders.

Selection Notes

Select this microcontroller when a low-power, cost-effective solution with moderate processing speed is required. The 40 MHz clock speed and 16 KB Flash are suitable for basic control tasks. Ensure the application requires the specific 32-LQFP package dimensions and the 2.7V to 5.5V supply range. Verify that the integrated ADC count meets the analog input requirements without needing external multiplexers.

Part Context

This component belongs to the NXP Kinetis KEA series, designed for entry-level applications requiring reliable performance. The KEA family targets cost-sensitive markets with optimized power consumption. The C9 variant specifically denotes the commercial temperature grade within the broader KEA product line, distinguishing it from automotive or extended temperature options.

Replacement Considerations

Consult official NXP cross-reference guides for compatible alternatives. Verify pin compatibility and software library support if substituting with other KEA series devices. Ensure any replacement maintains the same package footprint and electrical characteristics.
