XMC6521SCQ040XAAXUMA1

Overview

The XMC6521SCQ040XAAXUMA1 is a wireless power controller within the Infineon XMC1000 family, designed for Qi single coil 15W inductive MP-A11 desktop transmitters. It integrates a 32-bit ARM Cortex-M0 processor core with an on-chip MATH coprocessor. The device operates on a 3.3 V or 5.5 V supply and features Flash memory with ECC and SRAM with parity. Key peripherals include four USIC channels for communication, analog frontends for voltage and current sensing, and industrial control peripherals such as PWM channels for full bridge coil drivers. It is housed in a VQFN-40 package and supports an ambient operating temperature range of -40°C to 105°C.

• On-chip Flash (with ECC) and SRAM (with parity)
• Four USIC channels supporting UART and IIC interfaces

Applications

• Qi single coil 15W inductive MP-A11 desktop transmitters

Procurement Notes

Verify the specific ordering code XMC6521SC-Q040X with authorized distributors to confirm availability and lead times. Ensure compliance with RoHS standards and check for any specific handling requirements related to moisture sensitivity levels during storage and assembly processes.

Selection Notes

Select this component for applications requiring dedicated wireless power transmission control compliant with the Qi standard. Consider the VQFN-40 package constraints and the need for external components to support the high-current PWM outputs. Verify that the system design accommodates the specified 3.3 V to 5.5 V supply voltage range and thermal dissipation requirements for the VQFN-40 package.

Part Context

This part belongs to the XMCxxxxSC series, a subset of the broader XMC1000 microcontroller family. While sharing the ARM Cortex-M0 core architecture with other XMC1000 devices like the XMC1400 or XMC1300, the XMCxxxxSC series is specifically optimized with specialized peripherals for wireless power control, such as dedicated PWM channels for coil drivers and analog frontends for sensing.

Replacement Considerations

Direct replacements within the same derivative line include other XMCxxxxSC-Q040X variants such as the XMC6511SC-Q040X or XMC7531SC-Q040X, depending on the required power level and transmitter type. Cross-family migration to general-purpose XMC1000 devices requires significant peripheral reconfiguration.
