Procurement Notes

Verify the specific suffix 'PVXE' corresponds to the 20-pin SSOP package and extended temperature range. Confirm AEC Q100 qualification status if automotive compliance is required. Check current availability as Infineon manages the product portfolio post-acquisition. Ensure development tools like PSoC Designer are compatible with the selected device variant.

Selection Notes

Select this component when a single chip must replace multiple discrete MCU and analog components. The configurable architecture allows optimization of pin count and peripheral usage. Consider the 12 MHz speed limit compared to higher-speed variants. Evaluate the 20-pin package constraints against total GPIO requirements. Verify power supply compatibility with the specified voltage range.

Part Context

This part belongs to the CY8C21x34 family within the PSoC 1 series. It shares the core M8C architecture with other members like the CY8C21534. The primary distinction lies in the package type and specific pinout configuration. The device integrates both digital logic and analog signal processing capabilities on a single die.
