Procurement Notes

Verify the specific suffix 'KP' against official Infineon or Cypress documentation, as standard listings typically use 'PVXI'. Confirm package dimensions and pinout compatibility if substituting. Check RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the source provides valid traceability for this specific variant.

Selection Notes

Select this component when an 8-bit MCU with mixed-signal capabilities is required. It is suitable for designs needing programmable analog blocks alongside digital logic. Consider the 24MHz processing speed and available I/O count for performance requirements. Evaluate the 28-pin SSOP package constraints for PCB layout.

Part Context

This part belongs to the Cypress Semiconductor PSoC 1 series, now managed by Infineon Technologies. The CY8C24xxx series represents mixed-signal array devices combining an 8-bit CPU with configurable analog and digital blocks. These components are designed to reduce system complexity by integrating peripheral functions directly onto the silicon die.

Replacement Considerations

Standard equivalents include CY8C24423A-24PVXI. Verify pin-to-pin compatibility and software register compatibility before substitution. Check for any differences in package marking or thermal characteristics between variants.
