料号： XMC4104Q48F128BAXUMA1 ✓ 量产中XMC4104Q48F128BAXUMA1 概述
A microcontroller is a programmable integrated circuit that combines a processor core, nonvolatile program memory, volatile data memory, peripherals, and I/O in one device. The XMC4000 family belongs to the ARM Cortex-M4 microcontroller hierarchy and targets embedded industrial control, where deterministic real-time execution, compact packaging, and a broad set of peripheral interfaces are important. The XMC4104-Q48F128-BA specifically combines 128 KB flash with 20 KB SRAM.
The primary features verified for this device include ARM Cortex-M4 processing at 80 MHz, 128 KB of flash, 20 KB of SRAM, and a 1.3 V/3.3 V supply arrangement. Its 48-pin VQFN package with exposed pad supports compact surface-mount layouts while providing a thermal and electrical connection to the board. Distributor listings also identify RoHS compliance for the exact orderable MPN.
The Cortex-M4 architecture combines a 32-bit processing path with integrated high-performance code and data memory and a nested-vectored interrupt structure. Operating the core at 80 MHz provides additional scheduling headroom for protocol handling, control-loop execution, and supervisory logic. The 128 KB flash budget supports embedded firmware and configuration data, while 20 KB SRAM accommodates working variables, stacks, and buffered data.
Typical application categories for an industrial Cortex-M4 microcontroller of this class include industrial automation controllers, building automation modules, motor and power conversion supervisory control, communication gateways, and embedded sensor-control systems. The XMC4104 is suitable where a compact 48-pin surface-mount MCU, moderate flash capacity, and real-time 80 MHz processing are required without moving to a larger package or higher-memory device.
Designers should use the manufacturer datasheet and package drawing to confirm every pin, peripheral mapping, exposed-pad connection, decoupling requirement, and supported operating condition before layout. The exposed pad must be handled according to the official land-pattern guidance, and the 3.3 V rail must be filtered close to the device. Firmware should also account for the device-specific startup, clock, and peripheral configuration sequences rather than relying on generic Cortex-M assumptions.

典型应用
XMC4104Q48F128BAXUMA1 适用于 6 应用s: Industrial Automation Controller, Building Automation Module, Power Conversion Supervisory Control, Industrial Communication Gateway, Motor and Actuator Control, Embedded Sensor Control.
Industrial Automation Controller
The XMC4104Q48F128BAXUMA1 fits compact industrial automation controllers that require deterministic 80 MHz Cortex-M4 processing in a 48-pin surface-mount package. Its 128 KB flash provides room for control firmware, parameter tables, and diagnostics, while 20 KB SRAM supports working state, interrupt routines, and communication buffers. The device can sit between field sensors, actuator drivers, and an industrial communications controller, reducing the need for a separate processor. Engineers should confirm the exact peripheral mix and pin assignments in the Infineon datasheet, then isolate analog and power interfaces around the exposed-pad VQFN footprint.
推荐
Building Automation Module
The XMC4104Q48F128BAXUMA1 is suitable for building automation modules that coordinate sensors, room controls, and networked actuators. Its 80 MHz Cortex-M4 core provides processing headroom for protocol tasks and embedded control logic, and its 128 KB flash accommodates firmware and configuration data without requiring a large external memory device. The 20 KB SRAM is useful for buffering received commands and maintaining real-time operating state. In a controller PCB, the VQFN exposed pad should be connected according to the manufacturer package guidance, with local supply bypassing placed close to the device.
推荐
Power Conversion Supervisory Control
The XMC4104Q48F128BAXUMA1 can serve as the supervisory controller in a digital power system where a fast MCU handles sequencing, fault reporting, and communication. At 80 MHz, the Cortex-M4 core has substantial instruction throughput for control tasks, while 128 KB flash and 20 KB SRAM provide a practical memory partition for firmware and telemetry. It is not presented here as the power-conversion switching device itself; instead, it can supervise enable sequencing, monitor status signals, and report faults. The final design must verify the required timer, communication, analog, and fault-response resources.
推荐
Industrial Communication Gateway
The XMC4104Q48F128BAXUMA1 fits communication gateways that translate between local industrial interfaces and higher-level networks. Its 80 MHz ARM Cortex-M4 core can execute protocol stacks alongside supervisory tasks, while 128 KB flash supports firmware updates and 20 KB SRAM accommodates packet buffers and state. The 48-pin VQFN package allows a compact controller board, although the exact UART, CAN, Ethernet, or other interface availability must be confirmed from the verified device documentation. PCB layout should separate communication interfaces from sensitive analog and clock circuitry.
推荐
Motor and Actuator Control
The XMC4104Q48F128BAXUMA1 is appropriate for supervisory control in motor and actuator systems where the MCU executes sequencing, diagnostics, and real-time command logic. The 80 MHz Cortex-M4 core provides computation margin beyond simple supervisory loops, while 128 KB flash and 20 KB SRAM fit embedded control software, calibration values, and short-term command buffers. The microcontroller should remain separated from high-current switching stages through suitable gate drivers and interface circuits. Exact PWM, capture, position-feedback, and protection resources must be validated against the manufacturer documentation before hardware allocation.
推荐
Embedded Sensor Control
The XMC4104Q48F128BAXUMA1 can act as the local control processor in a sensor-rich embedded module, combining sampling coordination, filtering, threshold management, and data transfer. Its 128 KB flash is sufficient for moderate embedded firmware and calibration tables, while 20 KB SRAM supports acquisition buffers and protocol state. The 80 MHz core allows useful processing margin without requiring a high-power application processor. Designers should verify the required ADC, timer, serial-interface, and analog functions, while accounting for digital-switching noise and providing clean grounding around any precision measurement circuitry.

设计说明
Use the Infineon package drawing and recommended land pattern rather than constructing a generic VQFN-48 footprint. Place the required input and output capacitors close to their associated supply pins, keep the exposed-pad connection unobstructed, and provide adequate ground-via density beneath the device. The exposed pad is part of the thermal and electrical design, so its connection and solder-joint process must follow the manufacturer package guidance.
The listed 1.3 V/3.3 V arrangement must be implemented with separate, stable supply rails and appropriate sequencing. Confirm which supply belongs to the core and which belongs to the I/O domain in the complete datasheet before assigning pins. Keep high-current switching nodes and inductive components away from the MCU supply paths, and validate startup, shutdown, brownout, and reset behavior in the final system rather than relying only on nominal voltage values.
Preserve a clean return path for the exposed pad and use a solid ground reference under the device. Route high-speed or sensitive signals away from supply inductors, power-stage switching nodes, and clock sources. If the XMC4104 performs precision measurements, partition analog inputs and their reference components away from digital interfaces, use short guarded traces, and connect analog and digital ground systems according to the complete system grounding strategy.
Do not treat the shortened manufacturer code XMC4104-Q48F128-BA as proof that every ordering suffix is interchangeable. Confirm the full orderable MPN, package, temperature grade, qualification level, flash configuration, and shipping format. Similarly, the VQFN-48-53 label alone does not prove that every XMC4104 variant is pin-to-pin compatible; compare the official pin table and errata before releasing a substitution.
合规信息
The exact MPN is explicitly identified as RoHS compliant in the verified LCSC result. It is an industrial MCU rather than an automotive-qualified variant, so AEC-Q100 is not applicable. Other declarations were not present in the supplied data and are therefore recorded as unknown.
