Product details

Overview

XMC4108Q48K64BAXUMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 64 KB Flash, 20 KB SRAM, and VQFN-48 package. It integrates dual 12-bit VADCs (8 channels each), two 12-bit DACs, four HRPWM channels, CCU4/CCU8 timers, MultiCAN (2 nodes), and four USIC serial interfaces. Designed for industrial motor control and power conversion systems requiring real-time analog feedback and precise PWM timing.

For engineers reviewing the XMC4108Q48K64BAXUMA1 datasheet, XMC4108Q48K64BAXUMA1 pinout, XMC4108Q48K64BAXUMA1 application, or XMC4108Q48K64BAXUMA1 equivalent, key selection criteria include operating temperature range (–40°C to +125°C), integrated analog peripherals (VADC/DAC), industrial-grade CAN and USB device interface, and VQFN-48 thermal performance in compact drive modules.

Technical Context

The XMC4108Q48K64BAXUMA1 implements a deterministic real-time architecture centered on the ARM Cortex-M4 core with hardware FPU and MPU. Its peripheral subsystem includes dedicated motor control units: CCU8 for high-precision three-phase PWM generation and POSIF for absolute position decoding from incremental encoders or resolvers.

Analog signal chain integration is tightly coupled - VADC inputs feed directly into CCU4/CCU8 trigger events, enabling synchronous sampling of current/voltage at switching edges. The USIC modules support configurable serial protocols (UART/IIC/IIS/SPI/LIN) with independent clock domains, allowing concurrent communication with sensors, displays, and host controllers without CPU intervention.

FAQ

What is the maximum operating frequency of the XMC4108Q48K64BAXUMA1?

The XMC4108Q48K64BAXUMA1 operates at a maximum CPU frequency of 80 MHz, derived from its internal PLL locked to an external crystal (1–20 MHz). This frequency is guaranteed across the full industrial temperature range (–40°C to +125°C) with appropriate VDDP (1.3 V) and cooling per the thermal specifications in the datasheet.

Does this MCU support hardware-based functional safety features?

Yes - it includes a Window Watchdog Timer (WDT), memory protection unit (MPU), lockstep-capable debug interface, and hardware CRC engine. While not ASIL-certified out-of-box, these features form the foundation for IEC 61508 SIL2-compliant system design when implemented with certified software libraries and external monitoring circuits.

Can the VQFN-48 package be hand-soldered or reworked reliably?

The PG-VQFN-48-53 package (7 × 7 mm, 0.5 mm pitch) is compatible with standard reflow profiles (J-STD-020) and supports visual inspection of solder joints. Hand-soldering is not recommended due to thermal pad accessibility and fine-pitch leads; use hot-air rework stations with preheating and IR profiling for reliable repair.

Is USB device functionality self-contained without external components?

Yes - the XMC4108Q48K64BAXUMA1 integrates a full-speed USB 2.0 device PHY. Only two 22-Ω series resistors on DP/DM lines and a 1.5-kΩ pull-up on DP (to 3.3 V) are required. No external transceiver, crystal, or voltage regulator is needed for basic USB enumeration and CDC/DFU class operation.
