Procurement Notes

Verify the component status before procurement as this specific part number may be marked as Not Recommended for New Designs (NRND) or End-of-Life (EOL). Confirm availability through authorized distributors and check for valid datasheet revisions. Ensure that the QFN-28 package dimensions and pinout match your PCB footprint requirements. Validate that the operating voltage and temperature ranges meet your system specifications.

Selection Notes

Select this MCU when a high-performance 8-bit solution with integrated analog peripherals is required. It is suitable for designs needing fast execution speeds combined with precise signal acquisition via the 10-bit ADC. Consider the available I/O pins and communication interfaces against your connectivity needs. Evaluate the power consumption characteristics if battery operation is a priority, noting the available power-saving modes.

Part Context

This component belongs to the C8051F36x family of mixed-signal microcontrollers from Silicon Labs. The family shares a common architecture but varies in memory size, package type, and peripheral count. The C8051F367 variant specifically offers 32 kB Flash and is housed in a 28-pin QFN package. It is part of a broader series designed for cost-effective, high-integration embedded applications.

Replacement Considerations

Check for other members of the C8051F36x family with compatible pinouts and memory sizes. Consult Silicon Labs documentation for officially recommended substitutes if this part is discontinued. Ensure any replacement maintains the required 8051 compatibility and peripheral set.
