XMC4100Q48K128ABXUMA1 - 80MHz Cortex-M4 MCU | Infineon
MPN: XMC4100Q48K128ABXUMA1 ✓ ActiveXMC4100Q48K128ABXUMA1 Overview
An Arm Cortex-M4 microcontroller is a 32-bit embedded processing device built around the ARM Cortex-M4 processor core. This MCU family belongs to the hierarchy of embedded processors, microcontrollers, and semiconductor devices used in real-time control systems. Unlike a general-purpose application processor, the XMC4100 is designed for compact, deterministic embedded operation where peripherals, interrupt handling, timing, and low board area are central to the design.
Key features include 128 KB of Flash for firmware and 20 KB of SRAM for working memory, an 80 MHz maximum clock, and integrated CAN/LIN networking suitable for industrial communications. The 48-pin VQFN package supports a dense PCB layout while exposing the required digital interfaces and control resources. The part is identified as an industrial XMC4000-family device, making it appropriate for motor drives, motion control, and connected automation systems.
The XMC4100 architecture is intended for real-time embedded control, where timer and PWM peripherals can generate deterministic control signals while CAN and LIN interfaces connect the controller to sensors, actuators, and system networks. The 128 KB Flash capacity provides practical space for control algorithms, communication stacks, diagnostics, and parameter storage, while the 20 KB SRAM supports working state, buffers, and interrupt-driven routines.
Typical uses include industrial motor-drive controllers, motion-control modules, distributed automation nodes, CAN-connected equipment, LIN subnetwork controllers, and compact embedded control systems. CAN/LIN networking and timer/PWM resources make the device useful where multiple nodes must coordinate sensor inputs and actuator outputs within a deterministic control loop.
Designers should verify the exact peripheral assignment, pin multiplexing, electrical limits, exposed-pad requirements, and package drawing against the manufacturer datasheet before layout. The VQFN-48-22 package has a central exposed thermal pad and requires careful soldermask and thermal design. Firmware development should account for startup configuration, clock setup, peripheral initialization, and the CAN/LIN interrupt requirements of the target system.
This page summarizes the verified manufacturer and distributor specifications for the XMC4100Q48K128ABXUMA1 and adds practical guidance for selecting, comparing, and integrating the microcontroller. Pricing and lifecycle details should be confirmed from current distributor inventory because the supplied search data confirms product availability information but does not provide a price table.

Typical Applications
XMC4100Q48K128ABXUMA1 is suitable for 6 applications: Industrial Motor Drive Controller, Motion Control Module, CAN-Connected Automation Node, LIN Subnetwork Control Module, Industrial Sensor Aggregator, Programmable Logic Controller.
Industrial Motor Drive Controller
The XMC4100Q48K128ABXUMA1 fits compact motor-drive controllers because its 80 MHz ARM Cortex-M4 core can execute real-time control algorithms while the integrated timer and PWM resources generate deterministic gate-control timing. Its 128 KB Flash provides room for algorithms, fault handling, calibration data, and field diagnostics, while 20 KB SRAM supports control state and communication buffers. CAN connectivity allows the drive to exchange commands and status with a supervisory controller. The engineering trade-off is that final motor performance depends on correctly configuring the PWM channels, timer synchronization, analog inputs, protections, and exposed-pad layout from the manufacturer documentation.
Recommended
Motion Control Module
The XMC4100Q48K128ABXUMA1 is appropriate for a compact motion-control module requiring deterministic timing without a high-end application processor. At up to 80 MHz, the Cortex-M4 core can calculate control loops, while timer/PWM peripherals support actuator command generation and position-related input processing. The 128 KB Flash accommodates control code and parameter sets, and the 20 KB SRAM is useful for real-time data paths. Its 48-pin VQFN footprint reduces board area, although exposed-pad layout and signal integrity remain critical. Engineers should size the external clock, sensing network, and communication interface around the exact peripheral mappings in the Infineon datasheet.
Recommended
CAN-Connected Automation Node
The XMC4100Q48K128ABXUMA1 works well as a CAN-connected automation node because it combines an 80 MHz Cortex-M4 processor with CAN networking in a compact 48-pin VQFN package. It can run local control and diagnostic logic while exchanging setpoints, status, and alarms over the industrial network. The 128 KB Flash can hold a communication stack and application firmware, while 20 KB SRAM accommodates packet processing and sensor state. A practical design should include proper CAN transceiver selection, termination, isolation or protection as required, and careful separation between communications and sensitive analog paths. Verify transceiver levels and the selected MCU interface against the final board requirements.
Recommended
LIN Subnetwork Control Module
The XMC4100Q48K128ABXUMA1 can serve as a LIN-connected module for distributed low-speed control networks used in industrial equipment and actuators. Its 80 MHz Cortex-M4 core provides more than enough control bandwidth for protocol handling and local logic, while CAN/LIN connectivity avoids requiring a separate communications controller. The 128 KB Flash supports stack code, diagnostics, and application firmware, and the compact PG-VQFN-48-22 package assists space-constrained designs. LIN implementations still require a qualified transceiver, correct bus termination, filtering, and fault recovery. The exact LIN peripheral resources and pin assignments should be confirmed from the datasheet and relevant Infineon errata.
Recommended
Industrial Sensor Aggregator
The XMC4100Q48K128ABXUMA1 is suitable for an industrial sensor aggregator that must normalize inputs, run diagnostics, and publish results over a vehicle or industrial network. Its 80 MHz 32-bit core supports moderate signal-processing and control workloads, while 128 KB Flash and 20 KB SRAM provide practical memory for buffers, configuration, and filtering. The timer resources help maintain deterministic sampling schedules, and CAN or LIN allows the module to connect to remote sensors and actuators. Board-level design must include careful grounding, input protection, analog conditioning, and decoupling. Verify the available GPIO, analog channels, and alternate functions because the supplied data confirms the family but not the complete pin matrix.
Recommended
Programmable Logic Controller
The XMC4100Q48K128ABXUMA1 can implement a compact programmable logic controller for equipment-level sequencing, monitoring, and motor command generation. Its 80 MHz Cortex-M4 core supports responsive interrupt handling, 128 KB Flash holds application and configuration logic, and 20 KB SRAM supports execution state and I/O buffers. CAN/LIN networking allows the controller to participate in a larger machine network, while timer/PWM resources provide deterministic outputs. Compared with a fixed-function PLC, the microcontroller gives designers freedom to consolidate functions in a compact device. Firmware development must include robust startup behavior, watchdog strategy, safe output states, and diagnostics appropriate to the controlled equipment.

Key Differentiators
- Verified industrial motor-control positioning (vs Generic Cortex-M4 MCUs without verified CAN/LIN equivalence)
- Compact 48-pin industrial control footprint (vs Larger-package Cortex-M4 alternatives)
- Memory configuration matched to the closest identified alternative (vs XMC4104Q48K128AB)
Design Notes
Follow the Infineon PG-VQFN-48-22 land pattern and exposed-pad recommendations rather than treating the device as a generic 48-pin QFN. Keep the exposed pad connected to the intended ground plane, verify the package terminal numbering, and review solder-mask and paste-area drawings for the exact ordering code. Incorrect pad numbering or paste volume can affect solderability, thermal performance, and EMI behavior even when the schematic is correct.
Place all decoupling capacitors as close as practical to the corresponding supply pins and the exposed ground pad. Use the exact capacitor values and placement guidance in the manufacturer datasheet and reference design rather than estimating values. The 3.3 V operating supply does not establish the allowable input range or transient tolerance; those limits must be checked directly in the XMC4100/XMC4200 electrical-characteristics tables before power-supply design.
Map every motor-control, communications, and debug signal to the exact multiplexed pin in the datasheet before committing the PCB. External clock, sensor, and communications lines may require controlled impedance, short return paths, and isolation from switching nodes. For CAN or LIN, select a compatible transceiver and preserve the required topology, protection, and grounding arrangement; firmware support alone does not provide bus-level electrical compliance.
Do not treat all XMC4000 derivatives with a Q48 footprint as automatically interchangeable. The supplied evidence supports XMC4104Q48K128AB as a same-family drop-in candidate because its Q48K128 configuration aligns with the target, but exact pin functions, peripherals, clock features, qualification, and errata must still be compared. A memory-size match alone is not sufficient evidence for production substitution.
Compliance Information
The supplied verified excerpts identify the product as an industrial Infineon XMC4000-family microcontroller but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
