Procurement Notes

Verify the specific suffix PVXI against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with required operating voltage and environmental conditions. Cross-reference pinout configurations for SSOP-20 layouts during PCB design. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement specifications.

Selection Notes

Select this component when a compact 8-bit MCU with integrated high-resolution ADC is required. The SSOP-20 package suits space-constrained designs. Evaluate the 16 kB Flash capacity against application code size requirements. Consider the 24 MHz operational speed for real-time processing needs. Verify peripheral availability matches system interface demands.

Part Context

This model belongs to the Infineon PSoC 1 series, designed for mixed-signal applications. It combines an 8-bit processor with programmable analog blocks. The series targets cost-sensitive markets while offering design flexibility. The CY8C27243 variant specifically offers moderate memory and I/O counts suitable for general-purpose control tasks.

Replacement Considerations

Check Infineon's official obsolescence notices for direct substitutes. Compare pin compatibility and peripheral sets with alternative PSoC 1 models. Verify electrical characteristics match existing design constraints before considering cross-references.
