Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'KC' against official Infineon/Cypress documentation to confirm package type and temperature grade details not explicitly detailed in the general datasheet summary. Ensure compatibility with PSoC Designer software versions for firmware development.

Application Specific Microcontrollers Selection Notes

Select this component when a small form factor with integrated capacitive sensing is required. The 16-pin QFN package suits space-constrained designs. Consider the 8 KB Flash limit for complex applications; larger variants like the CY8C20436A offer more memory if needed.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A series of programmable CapSense controllers. It shares architectural similarities with other members like the CY8C20246A but differs in memory size and pin count. The series is designed to replace multiple traditional MCU components with a single chip.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include CY8C20246A or CY8C20246AS for similar functionality with potential pinout variations. Verify package compatibility and memory requirements before substitution.
