Procurement Notes

Verify the specific suffix 'LKXA' against official Cypress/Infineon documentation to confirm package type and qualification status. Ensure compatibility with AEC Q100 requirements if used in automotive contexts. Confirm availability through authorized distributors as part numbers may have lifecycle variations.

Selection Notes

Select this component for designs requiring AEC Q100 qualification and integrated capacitive sensing capabilities. The 12 MHz M8C core provides sufficient processing for standard control tasks. Consider the 3.0 V to 5.25 V operating range when designing power supplies. Verify that the QFN-16 package fits the PCB layout constraints.

Part Context

This part belongs to the PSoC®1 family, which integrates configurable analog and digital blocks with a programmable interconnect. The CY8C20xxx series is designed to replace multiple traditional MCU-based components with a single chip solution. It combines a fast CPU with flexible on-chip memory and configurable I/O options.

Replacement Considerations

Check for direct substitutes within the CY8C20234 family or other AEC Q100 qualified PSoC devices. Verify pinout and memory configuration compatibility before substitution.
