Procurement Notes

Verify the specific suffix 'A' against official Infineon documentation, as standard listings often reference the 'I' variant. Confirm package dimensions and thermal characteristics match design requirements. Ensure compliance with RoHS directives if required for the target market. Cross-reference the manufacturer part number with current datasheets to confirm availability and revision status before finalizing procurement plans.

Selection Notes

Select this component when an 8-bit architecture with integrated analog peripherals is required. The 24 MHz speed and 8 KB memory suit moderate complexity control tasks. Consider the 28-SSOP package for space-constrained designs. Evaluate the 28-channel ADC resolution if high-precision analog input is necessary. Compare against other CY8C21xxx variants based on memory size and I/O count requirements.
