Procurement Notes

Verify the specific suffix '24PVXA' against official Cypress or Infineon documentation to confirm pinout compatibility and electrical characteristics. Ensure the source document explicitly lists this part number to avoid confusion with similar PSOC1 variants that may differ in memory size or package type. Cross-reference RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when an 8-bit MCU with integrated analog/digital programmability is required. The PSOC1 architecture allows customization of peripherals, reducing board space compared to discrete solutions. Consider the 24MHz speed and 8KB flash capacity for applications with moderate processing demands. Verify voltage requirements align with the 3V to 5.25V operational range.

Part Context

This microcontroller belongs to the PSOC1 family, which combines an 8-bit processor with configurable analog and digital blocks. Manufactured originally by Cypress Semiconductor, now part of Infineon Technologies, these devices target cost-sensitive and space-constrained designs. The CY8C21xxx series specifically offers a balance of performance and peripheral flexibility for general-purpose embedded applications.

Replacement Considerations

Consult official datasheets for direct pin-to-pin replacements within the CY8C21xxx series. Verify functional equivalence regarding memory size and peripheral availability before substituting.
