Procurement Notes

Verify the specific package type and temperature grade corresponding to the suffix D412T against the official Infineon ordering guide. Confirm that the required pin count and peripheral configuration match the specific variant selected. Ensure compatibility with the PSoC Creator IDE or ModusToolbox development environment before procurement.

Selection Notes

Select this component when high integration of analog and digital functions is required within a single chip. The PSoC 4200L family is suitable for designs needing flexible reconfigurable logic alongside standard communication protocols like CAN and USB. Consider the available GPIO count and memory size relative to application complexity.

Part Context

This part belongs to the PSoC™ 4200L family, which extends the PSoC™ 4 platform with enhanced low-power capabilities and secure expansion options. It shares architectural similarities with other PSoC 4 variants but distinguishes itself through specific memory configurations and peripheral sets tailored for cost-sensitive and power-constrained embedded applications.

Replacement Considerations

Check for direct cross-references within the PSoC 4200L family such as CY8C4246AXI-L423 or similar variants with matching package and speed grades. Verify pin-to-pin compatibility if substituting with older PSoC 4 generations like the 4100S series, noting potential differences in analog performance and peripheral availability.
