• Includes hardware accelerators for cryptographic operations

Applications

• Human-machine interface (HMI) controllers
• Capacitive touch sensing applications
• Smart home control panels

Procurement Notes

Verify the specific suffix DM405 against official Infineon documentation to confirm pinout and package variations. Ensure compatibility with existing board layouts due to the 68-QFN form factor. Check for moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this component when a balance of processing speed and analog flexibility is required. The PSoC architecture allows for customized peripheral configurations, reducing external component count. Consider the 48 MHz performance limit and available I/O count for system requirements.

Part Context

This part belongs to the PSoC 4200M series, designed for cost-sensitive embedded applications. It combines an ARM Cortex-M0 core with configurable analog blocks, distinguishing it from standard microcontrollers by offering hardware-level customization without software overhead.

Replacement Considerations

Consult Infineon's cross-reference tools for direct pin-compatible alternatives within the PSoC 4 family. Verify functional equivalence regarding flash size, RAM capacity, and peripheral availability before substitution.
