Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets or FIT reports before procurement.

Application Specific Microcontrollers Selection Notes

Select this component when a low pin count (16-pin) solution with integrated capacitive touch capabilities is required. Ensure the design utilizes the available GPIOs effectively given the limited pin count compared to higher-density variants.

Application Specific Microcontrollers Part Context

This part belongs to the PSoC CY8C20xx7/S series. It shares architectural similarities with other members like the CY8C20237 and CY8C20247, differing primarily in memory size and pin availability within the same package family.

Application Specific Microcontrollers Replacement Considerations

Check for CY8C20237 or CY8C20247 if different memory configurations are acceptable. Verify pin compatibility and peripheral availability for direct substitution.
