XMC4108Q48K64ABXUMA1 - 80MHz Cortex-M4 MCU | Infineon
MPN: XMC4108Q48K64ABXUMA1 ✓ ActiveXMC4108Q48K64ABXUMA1 Overview
An ARM Cortex-M4 microcontroller is a 32-bit embedded processor within the microcontroller hierarchy, combining a reduced-instruction-set processor core, memory, interrupt handling, and programmable peripherals on one integrated circuit. The XMC4000 family is positioned for industrial embedded systems where deterministic control, moderate flash capacity, SRAM, DMA-assisted data movement, and memory protection are useful without requiring a larger high-density MCU.
The XMC4108Q48K64ABXUMA1 provides a 64 KB (64K x 8) Flash program-memory configuration, 20 KB of SRAM, and an operating frequency of 80 MHz. Its MPU supports controlled memory access for embedded applications, while the eight-channel DMA controller can transfer data between memory and peripherals with reduced processor intervention. The verified supply voltage options are 1.3 V and 3.3 V, providing flexibility for low-voltage cores and 3.3 V peripheral rails when the board design supports the device requirements.
The package is identified as PG-VQFN-48-4 in distributor data, with 48 no-lead terminals and a square package shape. Infineon package code HVQCCN is also listed in the verified distributor record. Because the supplied sources identify the package and terminal count but do not provide a complete numbered pin map, the exposed-pad connection, or every alternate function, a complete pinout cannot be reproduced safely from the available evidence.
Typical uses include industrial sensor and actuator controllers, compact motor-control or condition-monitoring systems, embedded data-acquisition nodes, and industrial communications equipment. The 80 MHz Cortex-M4 core handles control logic, the DMA controller assists with data movement, and the MPU can provide isolation between software domains. Exact peripheral assignments, timer resources, and analog functions should be confirmed against the complete manufacturer datasheet before schematic capture.
For a new PCB, preserve the 48-pin land pattern, exposed-pad geometry, and manufacturer-recommended thermal-via arrangement. Decoupling, startup behavior, clock configuration, and programming should follow the datasheet rather than assumptions based on generic Cortex-M4 designs. Because the verified data does not include detailed pin definitions or electrical limits, those values must be checked before release to production.
This product page consolidates the verified manufacturer and distributor information into an engineer-focused record covering architecture, memory, temperature range, package identity, ordering variants, and sourcing limitations. It also distinguishes verified drop-in candidates from broader functional comparisons, avoiding an unsupported claim that a different microcontroller is pin-compatible without manufacturer documentation.

Typical Applications
XMC4108Q48K64ABXUMA1 is suitable for 6 applications: Industrial Sensor and Actuator Control, Condition Monitoring and Data Acquisition, Industrial Communication Gateway, Compact Motor-Control Module, Embedded HMI Control Processor, Low-Voltage Embedded Control Board.
Industrial Sensor and Actuator Control
The XMC4108Q48K64ABXUMA1 fits compact industrial sensor and actuator controllers because its 80 MHz Cortex-M4 core provides control-processing headroom while 20 KB of SRAM supports local buffers and the eight-channel DMA controller assists data movement. The verified XMC4108-Q48K64-BA ordering variant covers -40°C to +125°C. Engineers can place it between industrial sensors, communication circuitry, and output drivers, provided the complete datasheet confirms the required timers, ADC, and communication peripherals. Its MPU can also separate embedded software regions when the system architecture benefits from controlled memory access.
Recommended
Condition Monitoring and Data Acquisition
The XMC4108Q48K64ABXUMA1 is suitable for condition-monitoring and data-acquisition nodes where a controller must process several data streams while controlling communications. Its eight-channel DMA channels can reduce processor involvement during memory transfers, while the 80 MHz Cortex-M4 core handles state logic and higher-level analysis. With 64 KB of Flash and 20 KB of SRAM, the device can support compact firmware, acquisition buffers, and communication protocols. The selected analog inputs, sample rates, timers, and communication resources must be verified in the manufacturer datasheet because the supplied web evidence does not enumerate them.
Recommended
Industrial Communication Gateway
The XMC4108Q48K64ABXUMA1 can serve as the controller in a small industrial communication gateway when the application requires deterministic interrupt handling and peripheral data movement. The 80 MHz Cortex-M4 core processes protocol state, while the eight-channel DMA channels assist moving buffers among RAM and communication peripherals. Its 48-pin PG-VQFN-4 package supports compact board construction, and the verified industrial ordering range of -40°C to +125°C suits temperature-controlled equipment. Before selecting it, verify the required CAN, Ethernet, serial, or other interfaces against the exact XMC4108 datasheet and pin assignment.
Recommended
Compact Motor-Control Module
The XMC4108Q48K64ABXUMA1 is applicable to compact motor-control modules where the 80 MHz Cortex-M4 core can execute control algorithms and the eight-channel DMA controller can service time-critical data movement. The MPU provides a mechanism for memory isolation in more structured embedded software, while 20 KB of SRAM accommodates working state and control buffers. The available Flash of 64 KB supports a focused control application rather than a large graphical or connectivity-heavy firmware stack. Actual motor-control suitability depends on verified timer channels, PWM outputs, capture functions, analog interfaces, and package pin assignments.
Recommended
Embedded HMI Control Processor
The XMC4108Q48K64ABXUMA1 can act as the local control processor in a small embedded human-machine interface system, managing input events, display commands, and peripheral coordination. Its 32-bit Cortex-M4 architecture and 80 MHz operating frequency provide control performance without requiring the memory footprint of a high-end application processor. The 20 KB SRAM and 64 KB Flash are adequate for compact interfaces and moderate protocol stacks, although graphics complexity must be carefully constrained. The 48-pin VQFN package also helps reduce board area, subject to correct exposed-pad and thermal layout.
Recommended
Low-Voltage Embedded Control Board
The XMC4108Q48K64ABXUMA1 is relevant to low-voltage embedded control boards because the verified supply options include 1.3 V and 3.3 V. Designers can use the lower-voltage option for appropriate internal rails while supporting 3.3 V peripherals, provided the exact power-domain requirements are followed in the manufacturer datasheet. The 80 MHz Cortex-M4 core supports responsive control logic, and the MPU plus DMA controller provide useful architectural features for structured firmware. Detailed internal-regulator, I/O-level, decoupling, and power-consumption values were not present in the verified sources and must not be assumed.

Design Notes
Use the exact Infineon PG-VQFN-48-4 land pattern and exposed-pad guidance rather than a generic 48-pin QFN footprint. Confirm whether the exposed pad is tied to ground, the required via pattern, and the annular-ring dimensions against the current package drawing. Place the device’s high-current supply connections and decoupling capacitors close to their assigned pins to minimize loop area.
Plan the supply rails around the verified 1.3 V and 3.3 V options, but obtain the complete minimum, maximum, regulator, and current requirements from the manufacturer datasheet before selecting components. Verify which peripherals operate at 1.3 V and which use 3.3 V, and confirm that every external signal remains within its pin’s allowed voltage domain. Use the manufacturer’s startup and decoupling requirements as the basis for the power tree.
The exposed pad is an important thermal and electrical feature of a VQFN package. Follow the recommended via-in-pad or via-near-pad arrangement and provide adequate ground-plane copper where the pin assignment permits. Actual junction-temperature margin depends on operating frequency, load, ambient temperature, and board construction, so use the Infineon thermal model rather than assuming that the small package dissipates negligible heat.
Do not treat an ordering-suffix match as proof of interchangeability. Compare the complete Infineon ordering code, temperature grade, package, flash configuration, and delivery option. Likewise, do not infer that a Cortex-M4 competitor with a 48-pin package is drop-in compatible: verify every power, ground, debug, analog, timer, communication, and alternate-function connection against both datasheets before modifying an existing PCB.
Compliance Information
The verified manufacturer and distributor results identify an industrial MCU and its temperature range but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim has been inferred.
