XMC7541SCQ040XAAXUMA1

Overview

The XMC7541SCQ040XAAXUMA1 is a microcontroller within the XMC1000 Family, designed for wireless power systems. It features an ARM Cortex-M0 core and supports single coil high-power inductive transmission up to 80W. The device operates on a 3.3 V or 5.5 V supply with an ambient temperature range of -40°C to 105°C. Key peripherals include four USIC channels, two PWM channels for full bridge coil drivers, one PWM channel for bridge supply control, and analog frontends for voltage, current, and temperature sensing. It is housed in a VQFN-40 package.

Feature Summary

• ARM Cortex-M0 32-bit processor core with MATH coprocessor
• On-chip SRAM with parity and Flash memory with ECC
• Supports Qi standard single coil 80W high power inductive transmission
• Integrated analog frontends including ADCs, temperature sensor, and comparators

Applications

• Single coil 80W high power inductive transmitters
• Telecom and security infrastructure charging
• Commercial and industrial wireless power systems

Procurement Notes

Verify the specific ordering code XMC7541SC-Q040X with Infineon sales representatives or local distributors as detailed ordering information requires direct contact. Confirm that the package variant Q corresponds to the VQFN-40 form factor and that the temperature grade X covers the required -40°C to 105°C operating range for the target application environment.

Selection Notes

Select this derivative when designing for single coil high power inductive applications requiring up to 80W output. Ensure the system design accommodates the 3.3 V or 5.5 V digital supply voltage (VDDP) and provides adequate thermal management for the VQFN-40 package. Verify that the available GPIOs and peripheral counts meet the interface requirements for the coil driver and communication demodulator inputs.

Part Context

This component belongs to the XMCxxxxSC series, which addresses real-time control needs for wireless power systems. It is part of the broader XMC1000 Family of microcontrollers based on the ARM Cortex-M0 processor core. The datasheet describes a superset of features for the series, so specific availability should be confirmed against the device type synopsis.

Replacement Considerations

Other derivatives in the XMCxxxxSC family, such as the XMC7531SC-Q040X for 30W applications or the XMC6521SC-Q040X for 15W Qi desktop transmitters, may serve as alternatives if lower power ratings are sufficient. All share the same VQFN-40 package and core architecture.
