Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon or Cypress distributors. Confirm package marking and datasheet revision against official documentation. Check for end-of-life status as some sources indicate discontinuation. Ensure RoHS compliance certificates are available for regulatory requirements.

Application Specific Microcontrollers Selection Notes

Select this model when a dedicated CapSense controller with integrated M8C processing is required. Compare pin counts and memory sizes against alternatives like the CY8C20337 if fewer I/Os are sufficient. Verify voltage compatibility with the 1.71V to 5.5V operating range. Consider the 32-pin QFN footprint for PCB layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20xx7/S family of CapSense controllers. It shares architectural similarities with parts like the CY8C20434 and CY8C20467S, differing primarily in memory size and specific I/O configurations. The manufacturer transitioned from Cypress Semiconductor to Infineon Technologies.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes include other members of the CY8C20xx7 family such as the CY8C20434-12LQXI or CY8C20467S-24LQXI. Verify pin compatibility and software code migration requirements before replacing. Cross-reference specifications for clock speed and memory capacity differences.
