Procurement Notes

Verify the specific silicon revision and datasheet version when sourcing this component, as early documentation may be marked preliminary. Confirm that the 8-SOIC package dimensions match your PCB footprint design. Ensure compatibility with development tools such as PSoC Designer if firmware updates are planned. Check for any RoHS compliance status variations depending on the manufacturing date code.

Selection Notes

Select this model when an 8-bit architecture with significant analog capabilities is required in a minimal pin count package. It is suitable for applications needing a 14-bit ADC and configurable digital logic without external components. Consider alternative packages like PDIP or TSSOP if surface mount assembly is not feasible or if through-hole mounting is preferred for prototyping.

Part Context

This part belongs to the CY8C24xxx series of Programmable System-on-Chip microcontrollers by Infineon Technologies (formerly Cypress). The series is designed to reduce board space and component count by integrating analog and digital resources into a single chip. The CY8C24123 variant specifically targets cost-sensitive applications requiring moderate performance and mixed-signal functionality.

Replacement Considerations

Check for CY8C24123A-24SXI for updated revisions within the same family. Verify pinout compatibility before substituting with other CY8C24xxx variants.
