XMC7531SCQ040XAAXUMA1

Overview

The XMC7531SCQ040XAAXUMA1 is a microcontroller within the Infineon XMC1000 family, specifically designed for wireless power systems. It integrates a 32-bit ARM Cortex-M0 processor core with on-chip SRAM featuring parity and Flash memory with ECC. The device supports operating voltages of 3.3 V or 5.5 V and functions within an ambient temperature range of -40°C to 105°C. Key peripherals include four USIC channels for communication, analog front-end capabilities for voltage and current sensing, and dedicated PWM channels for coil driver and bridge supply control. It is housed in a VQFN-40 package.

Procurement Notes

Verify the specific ordering code against official Infineon documentation to ensure correct derivative selection. Confirm that the application environment meets the specified operating voltage and temperature ranges. Check for any required firmware programming, as some derivatives may require customer programming.

Selection Notes

Select this component for applications requiring a single coil 30W transmitter solution. Ensure the system design accommodates the VQFN-40 package dimensions and thermal requirements. Verify compatibility with the required communication protocols (UART/IIC) and analog sensing needs.

Part Context

This part 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 architecture.

Replacement Considerations

Other derivatives in the XMCxxxxSC series, such as XMC6521SC-Q040X or XMC7501SC-Q040X, offer different power levels or coil configurations. Verify functional equivalence if substituting.
