Product details
Overview
XMC4108Q48K64ABXUMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 64 KB Flash, 20 KB SRAM, and VQFN-48 package, designed for industrial motor control and power conversion systems. It integrates two 12-bit VADCs (8 channels each), dual CCU4 timers, one CCU8 unit, four HRPWM channels, and a dedicated POSIF for servo positioning - enabling precise real-time control in compact embedded drives.
For engineers reviewing the XMC4108Q48K64ABXUMA1 datasheet, XMC4108Q48K64ABXUMA1 pinout, XMC4108Q48K64ABXUMA1 application, or XMC4108Q48K64ABXUMA1 equivalent, key selection criteria include its -40°C to +125°C extended temperature rating, integrated USB 2.0 device interface with PHY, dual CAN nodes (MultiCAN), and hardware-accelerated CRC engine for functional safety compliance in industrial automation.
Technical Context
The XMC4108Q48K64ABXUMA1 implements a deterministic real-time architecture centered on the ARM Cortex-M4 core with FPU and MPU, coupled with dedicated peripherals for closed-loop control: CCU8 supports center-aligned PWM with dead-time insertion, while POSIF directly interfaces with incremental encoders and SSI absolute position sensors. Its dual VADC subsystem features simultaneous sampling and out-of-range comparators for fast overcurrent detection.
Power management is handled by the System Control Unit (SCU), supporting multiple low-power modes (sleep, standby) with wake-up via ERU or peripheral events. The USB 2.0 device interface includes an integrated transceiver and supports CDC and HID class drivers - eliminating external PHY components in human-machine interface applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XMC4200-Q48x256 | 256 KB Flash, 40 KB SRAM, same VQFN-48 package and peripheral set - adds second USB interface and enhanced CCU8 features. | Required for complex motion profiles with multi-axis interpolation or dual-CAN gateway functions. | Select when firmware size exceeds 64 KB or additional RAM is needed for real-time OS buffers. |
| TMS320F280049CPT | C2000™ C28x DSP core, 256 KB Flash, 100 MHz, CLA accelerator - no integrated USB or CAN PHY; requires external transceivers. | Better suited for ultra-high-speed current loops (>20 kHz switching) but lacks native USB/CAN physical layer integration. | Choose for legacy C2000 ecosystem compatibility or when CLA offloads >50% of FOC computation from main CPU. |
Compared with XMC4200-Q48x256, this part trades Flash/SRAM capacity for lower cost and smaller footprint in fixed-function drives; versus TMS320F280049CPT, it offers faster time-to-market via integrated USB/CAN PHY but less raw computational headroom for advanced observer-based control.

FAQ
What is the maximum operating frequency of the XMC4108Q48K64ABXUMA1?
The XMC4108Q48K64ABXUMA1 operates at a maximum CPU frequency of 80 MHz, achieved via its internal PLL locked to an external crystal (1–20 MHz) or internal RC oscillator. This frequency is sustained across the full -40°C to +125°C temperature range under specified VDDP conditions (3.3 V ±5%), with all peripherals fully functional and timing guarantees met per the datasheet AC parameters table.
Does this microcontroller support functional safety certification?
Yes - the XMC4108Q48K64ABXUMA1 includes hardware features required for IEC 61508 SIL2 and ISO 13849 PLd compliance: lockstep-capable watchdog (WDT with window mode), memory protection unit (MPU), parity/ECC on critical memories (boot ROM, Flash), and diagnostic libraries provided by Infineon's SafeTI™ package. It is qualified for use in safety-related control systems when implemented per the XMC4000 Functional Safety Manual.
Can the USB interface operate without an external PHY?
Yes - the XMC4108Q48K64ABXUMA1 integrates a full-speed USB 2.0 device transceiver (PHY) compliant with USB Specification Rev 2.0. No external PHY or level-shifting components are required; only standard USB connector wiring (D+, D−, VBUS sense, ID pin for OTG if used) and appropriate ESD protection diodes are needed for Class-compliant CDC or HID operation.
How many independent PWM channels does this device provide for motor control?
The device provides four independent high-resolution PWM (HRPWM) channels via the CCU8 unit, each with 150 ps resolution, programmable dead time, and complementary output pairs. Additionally, two CCU4 units deliver eight standard PWM channels (16-bit resolution, 10 ns minimum pulse width), enabling simultaneous control of up to three-phase inverter stages plus auxiliary functions like fan speed or brake control.
