Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm current availability status as distribution channels may report limited stock or end-of-life notices for this specific variant. Ensure compatibility with existing PCB footprints for the TQFP-48 package before procurement.

Selection Notes

Select this model for designs requiring a balance of processing speed and analog integration. The wide voltage range allows flexibility in power supply design. Consider the 48 MHz performance limit and 64 kB memory size against application requirements. Verify temperature grade suitability for the intended operating environment.

Part Context

This part belongs to the Infineon PSoC 4200M family, designed for cost-sensitive embedded applications. It combines a standard ARM Cortex-M0 processor with Cypress's proprietary programmable analog architecture. The family targets applications needing precise analog signal conditioning alongside digital control logic.

Replacement Considerations

Check for direct pin-compatible substitutes within the same PSoC 4200M series. Verify if alternative suffixes (e.g., AZS) offer different temperature ranges or packaging options that meet project needs without redesigning the board.
