Procurement Notes

Verify the specific ordering code against official Infineon documentation to ensure correct derivative selection. Confirm package variant and temperature range specifications match application requirements. Consult local distributors for availability and lead times.

Selection Notes

Select this device for applications requiring dedicated wireless power control with real-time processing capabilities. Ensure the system design accommodates the 3.3 V or 5.5 V supply options. Verify that the available GPIOs and peripheral interfaces meet the specific coil driver and sensor interface needs of the target wireless power topology.

Part Context

This part belongs to the XMCxxxxSC series, a subset of the broader XMC1000 family. While sharing the Cortex-M0 core architecture with other XMC1000 devices, the SC series is optimized with specific peripherals for wireless power control, such as high-current PWM outputs and specialized analog inputs for coil monitoring.

Replacement Considerations

Direct replacements within the same series include other XMCxxxxSC-Q040X derivatives with different power ratings or feature sets, such as XMC8511SC-Q040X or XMC7531SC-Q040X. Cross-family migration to standard XMC1000 devices requires significant software and hardware redesign due to peripheral differences.
