Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Ensure storage conditions account for moisture sensitivity level requirements prior to soldering.

Application Specific Microcontrollers Selection Notes

Select this model when 16 kB program memory and 28 GPIOs are required. The QFN-32 package suits space-constrained designs. Verify that the 1.71 V to 5.5 V operating range aligns with system power rails. Consider resource usage if implementing TS2000 haptics modules.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A series of PSoC 1 devices. It shares architectural similarities with CY8C20446H but differs in specific feature sets and performance characteristics defined by the 'A' suffix designation within the Infineon portfolio.

Application Specific Microcontrollers Replacement Considerations

CY8C20446A-24PVXI is a pin-compatible alternative in a different package. CY8C20436-24LQXIT offers reduced memory resources (8 kB Flash, 1 kB RAM) in the same package.
