Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure compatibility with existing design tools such as PSoC Designer. Check for any product termination notifications or lifecycle changes associated with this part number before finalizing supply chain decisions.

Selection Notes

Select this component when a design requires a combination of programmable analog blocks and a native USB interface without external components. The M8C core offers efficient processing for 8-bit applications. Consider the available GPIO count and block configuration relative to the specific pinout requirements of the target PCB layout. Evaluate the need for capacitive sensing features if touch input is required.
