Procurement Notes

Verify the specific suffix PVXE confirms the package type and temperature range against official datasheets. Confirm RoHS compliance status and lead-free manufacturing details. Ensure the ordering part number matches the exact speed grade and memory configuration required for your design. Cross-reference pinouts with the latest mechanical drawing to avoid layout errors.

Selection Notes

Select this component when mixed-signal programmability and low power are critical. Evaluate the available analog block resources against signal conditioning needs. Consider the Flash size for application code and data storage requirements. Verify that the 12 MHz clock speed meets real-time processing constraints without excessive power draw.

Part Context

This part belongs to the PSoC 2 family, designed for cost-sensitive applications requiring high integration. It replaces discrete microcontroller and peripheral solutions by consolidating functions onto one chip. The family emphasizes ease of development through software-configurable hardware blocks.

Replacement Considerations

Direct substitutes include other CY8C22xxx series variants with compatible pinouts and memory sizes. Verify functional equivalence in analog block count and I/O drive strength before swapping. Check for any differences in voltage ranges or operating temperatures.
