XMC6521SCQ040XXUMA1

Overview

The XMC6521SCQ040XAAXUMA1 is a wireless power controller within the Infineon XMC1000 family, designed for Qi single coil 15W inductive desktop transmitters. It integrates a 32-bit ARM Cortex-M0 processor core with MATH coprocessor capabilities. The device operates on a 3.3 V or 5.5 V supply and features up to 27 GPIOs and 8 GPIs. Key peripherals include four USIC channels for UART and IIC communication, analog frontends for voltage and current sensing, and industrial control peripherals comprising two PWM channels for full bridge coil drivers and one for bridge supply control. 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)
• Two PWM channels dedicated to full bridge coil driver control
• Four USIC channels supporting UART and IIC interfaces

Applications

• Qi single coil 15W inductive desktop transmitters
• Commercial and industrial wireless power systems
• Real-time control of wireless power controllers

Procurement Notes

Verify the specific ordering code against Infineon documentation to ensure correct derivative selection. Confirm that the system design meets the required operating conditions, including the 3.3 V to 5.5 V digital supply voltage range and the -40°C to 105°C ambient temperature specification. Ensure proper connection of the exposed die pad to board ground for thermal and electrical performance.

Selection Notes

Select this component for applications requiring Qi 15W transmitter control. Ensure the design accommodates the VQFN-40 package dimensions. Verify that the external crystal oscillator frequency falls within the 8 MHz to 20 MHz support range if used. Check that the application does not exceed the absolute maximum ratings for junction temperature or pin voltages.

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 core. Other derivatives in this series include models for sub-surface infrastructure, telecom, security, and resonant multi-device transmitters.

Replacement Considerations

Other devices in the XMCxxxxSC-Q040X series, such as the XMC6511SC-Q040X or XMC7531SC-Q040X, share the same package and core architecture but differ in pre-programmed functionality and target power levels. Substitution requires verification of software compatibility and peripheral configuration.
