Procurement Notes

Verify the suffix 'KC' against official Infineon/Cypress documentation to confirm specific qualification or packaging variations. Ensure compatibility with existing design files and check for any RoHS compliance certificates associated with this specific variant before procurement.

Selection Notes

Select this component when a compact 8-bit MCU with integrated programmable analog/digital resources is required. It is suitable for designs needing CapSense functionality without external sensors. Compare pin counts and memory sizes against other CY8C20xxx variants to ensure optimal fit for the application constraints.

Part Context

This part belongs to the PSoC 1 CY8C20xxx series, which combines a fast M8C processor with programmable mixed-signal blocks. This architecture allows designers to replace multiple discrete components with a single IC, reducing board space and complexity in embedded applications.

Replacement Considerations

Check for direct substitutes within the CY8C203xx series with identical pinouts and memory configurations. Verify if alternative packages like SSOP are available if QFN is unsuitable.
