Procurement Notes

Verify the complete part number including suffixes against official Infineon documentation to ensure correct package type, temperature grade, and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current product lifecycle status as older variants may be discontinued or subject to last-time buy notices.

Selection Notes

Select this component when an 8-bit MCU with integrated analog programmability is required. Ensure the 28-channel ADC resolution meets your signal conditioning needs. Verify that the 8 kB Flash capacity is sufficient for your application firmware. Consider the SSOP-20 package dimensions for PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the Infineon PSoC 21x34 family, designed for mixed-signal applications. It combines an 8-bit CPU with configurable analog blocks, enabling reduction in external component count. The family targets cost-sensitive applications needing both digital control and analog signal handling in a single chip.

Replacement Considerations

Check for direct pin-compatible upgrades within the PSoC 21 series with higher memory or speed. Verify if newer generations like PSoC 4 or 6 offer better performance while maintaining software compatibility through migration tools.
