Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against Infineon's official documentation to confirm package type, lead finish, and tape/reel specifications. Ensure the component meets the required AEC Q100 qualification level for your target application environment.

Application Specific Microcontrollers Selection Notes

Select this model if your design requires AEC Q100 compliance combined with integrated capacitive sensing capabilities. The 16-pin QFN package limits the available GPIO count compared to larger packages; verify pin availability for your specific interface requirements.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A series of the PSoC 2 family. It shares architectural similarities with other devices in the series but is distinguished by its automotive qualification and specific memory configuration of 8 KB Flash and 1 KB SRAM.

Application Specific Microcontrollers Replacement Considerations

Check for direct cross-references within the CY8C20x36A family. Ensure any substitute maintains AEC Q100 qualification and compatible pinout if board-level replacement is intended.
