XMC4108Q48K64BAXUMA1 - 80MHz Cortex-M4 64KB MCU | Infineon
料号： XMC4108Q48K64BAXUMA1 ✓ 量产中XMC4108Q48K64BAXUMA1 概述
The XMC4000 family belongs to the industrial microcontroller hierarchy: MCU, embedded microcontroller, 32-bit microcontroller, Arm Cortex-M4 microcontroller, and industrial control processor. Compared with general-purpose entry microcontrollers, the XMC4108 family is oriented toward connected industrial equipment, sensors, actuators, communication modules, and control platforms where predictable execution and a compact surface-mount footprint are important.
Key verified features include an Arm Cortex-M4 processor core operating at 80 MHz, 64 KB of flash memory organized as 64K x 8, and 20 KB of SRAM. The official Infineon product-page snippet specifies an industrial temperature range of -40 °C to 125 °C. The device is supplied in a 48-pin PG-VQFN package with an exposed pad according to distributor data, making it suitable for compact PCB designs requiring high-density placement and improved thermal spreading.
The XMC4108Q48K64BAXUMA1 is appropriate for industrial automation, motor and motion control, communications equipment, building automation, sensor hubs, and embedded control systems. Its 80 MHz Cortex-M4 performance supports interrupt-driven control, digital signal processing, and communication protocol handling while retaining a unified memory architecture and low component count. The 64 KB flash capacity is suitable for firmware, configuration data, and application code, while the 20 KB SRAM supports working memory, stack, buffers, and peripheral data structures.
Designers should verify the exact pin assignment, exposed-pad connection, decoupling requirements, clock configuration, and peripheral mix against the manufacturer datasheet before layout release. The verified data confirms the core, memory size, frequency, package family, supply indication, and industrial temperature range, but it does not provide a complete electrical table or detailed pinout. This product page therefore distinguishes verified attributes from parameters requiring confirmation from the XMC4100/4200 series documentation.

典型应用
XMC4108Q48K64BAXUMA1 适用于 6 应用s: Industrial Automation Controllers, Motor and Motion Control, Building Automation and HVAC, Industrial Sensor Hubs, Industrial Communication Equipment, Embedded Control and Data Acquisition.
Industrial Automation Controllers
The XMC4108Q48K64BAXUMA1 fits compact industrial automation controllers because it combines an 80 MHz Arm Cortex-M4 core with 64 KB flash and 20 KB SRAM. Those resources support state-machine control, digital filtering, field-bus protocol handling, and supervisory logic in equipment where a small 48-pin PG-VQFN footprint is valuable. Its verified -40 °C to 125 °C industrial temperature range also aligns with machinery, process equipment, and factory-control environments. Design the power system, communications interface, and I/O expansion around the MCU while validating pin multiplexing and timing from the manufacturer documentation.
推荐
Motor and Motion Control
The 80 MHz Cortex-M4 core in XMC4108Q48K64BAXUMA1 is suitable for digital motor-control supervisory functions, including current-loop calculation support, encoder processing, speed reference management, and protection sequencing. The 20 KB SRAM allows useful working space for control variables and communication buffers, while 64 KB flash can hold compact control firmware. The MCU should operate alongside external gate drivers, power semiconductors, current sensors, and protection circuitry rather than driving a motor stage directly. Its -40 °C to 125 °C rating supports industrial equipment, subject to correct thermal and timing design.
推荐
Building Automation and HVAC
The XMC4108Q48K64BAXUMA1 can serve as the embedded controller for building-automation nodes, room controllers, HVAC supervisory boards, and connected sensor modules. Its 3.3 V supply indication supports integration into compact low-voltage control electronics, while the Cortex-M4 processor handles scheduled tasks, sensor fusion, control logic, and communication protocols. The 64 KB flash is appropriate for a focused application image, and 20 KB SRAM can support protocol buffers and state management. Product teams must still verify low-power modes, timer resources, communications peripherals, and the complete pin map in the manufacturer datasheet.
推荐
Industrial Sensor Hubs
The XMC4108Q48K64BAXUMA1 is appropriate for sensor aggregation and condition-monitoring nodes that must process several digital inputs while maintaining local control functions. At 80 MHz, its Arm Cortex-M4 core can execute filtering, calibration, threshold logic, and communication tasks concurrently through interrupts and peripherals. The 64 KB flash provides storage for application firmware and configuration logic, while the 20 KB SRAM accommodates samples, buffers, and protocol state. Its 48-pin PG-VQFN package supports compact assemblies, although the exposed-pad layout and signal integrity requirements must be implemented exactly as specified.
推荐
Industrial Communication Equipment
The XMC4108Q48K64BAXUMA1 can be used in protocol gateways, remote I/O modules, and industrial communication adapters where a compact 32-bit controller must manage frames, diagnostics, configuration, and local supervision. Its 80 MHz Arm Cortex-M4 performance provides useful instruction throughput for buffering and protocol state machines, while 64 KB flash accommodates application code and 20 KB SRAM supports packet buffers. The 3.3 V operating point simplifies integration with modern digital interface logic. Exact serial-interface capabilities, clock requirements, and multiplexing should be confirmed for each board because the supplied verified data does not enumerate every peripheral.
推荐
Embedded Control and Data Acquisition
The XMC4108Q48K64BAXUMA1 is well suited to compact data-acquisition front ends that combine digital sensors, timing-sensitive sampling, local filtering, and host communication. Its Cortex-M4 core can execute digital signal-processing operations, the 20 KB SRAM can buffer acquired data, and the 64 KB flash can store the control application. The -40 °C to 125 °C range supports industrial measurement equipment, while the compact VQFN package assists high-density instrument designs. System-level accuracy still depends on external analog front ends, reference components, sensors, isolation, and careful validation of ADC and timing requirements against the datasheet.

设计说明
Treat the exposed pad as a required thermal and electrical land. The verified package is PG-VQFN-48-53 with an exposed pad, but the supplied data does not specify pad dimensions, thermal resistance, or paste and via recommendations. Use the current Infineon package drawing and recommended PCB footprint rather than estimating them. Check the completed board’s copper area and thermal performance against the highest expected ambient temperature and processor activity.
Place all decoupling capacitors directly at the appropriate supply and ground pins, following the manufacturer’s recommended capacitance, voltage rating, and layout sequence. Because the verified data does not include a pin-by-pin power-supply table or recommended capacitor values, do not infer those requirements from generic Cortex-M4 designs. Confirm every power, ground, analog, clock, and exposed-pad connection against the official XMC4100/4200 series datasheet before fabrication.
Do not treat a same-family ordering code as automatically interchangeable without checking the package drawing, qualification status, and orderable suffix. In particular, verify whether XMC4108-Q48K64BA and XMC4108-Q48K64AB differ in temperature treatment, qualification, labeling, or customer-specific ordering information. Also confirm the complete memory map and peripheral configuration because the target product’s verified XUMA1 suffix is not fully described in the supplied search excerpts.
合规信息
The supplied verified snippets identify the device as an industrial microcontroller and provide its temperature range, but they do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields therefore remain unknown rather than assumed.
