Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Ensure compatibility with the required operating voltage and temperature ranges for the target environment. Cross-reference the manufacturer part number with current datasheets to confirm active status and availability.

Selection Notes

Select this component for designs requiring integrated capacitive touch sensing capabilities alongside standard 8-bit MCU functionality. Consider the 24 MHz performance limit and 8 kB memory size for code complexity. Evaluate the 28-channel ADC capability against sensor requirements. Confirm that the SSOP-20 package fits the board layout constraints.

Part Context

This part belongs to the CY8C21x34 series of PSoC devices, which combine digital logic with programmable analog blocks. The series is designed for applications needing low power consumption and mixed-signal integration. The M8C core provides efficient execution for 8-bit control tasks while supporting advanced peripheral configurations.

Replacement Considerations

Check for direct substitutes within the CY8C21x34 family with compatible pinouts and memory sizes. Verify if alternative packages or speed grades meet the design requirements without changing the functional specification.
