XMC4400F64K512BAXQMA1 - 120MHz Cortex-M4 MCU | Infineon
MPN: XMC4400F64K512BAXQMA1 ✓ ActiveXMC4400F64K512BAXQMA1 Overview
An Arm Cortex-M4 microcontroller is a 32-bit embedded processor in the microcontroller family, where the Arm Cortex-M core sits between a general-purpose microprocessor and a highly integrated embedded control device. The XMC4400 belongs to Infineon's XMC4000 industrial microcontroller family, combining real-time digital control with communication and analog-adjacent peripheral functions on one integrated circuit.
Key device features include a 120 MHz Cortex-M4 core, 512 KB of program flash, 80 KB of RAM, an integrated Ethernet MAC, and a 64-pin PG-LQFP package. The 150 ps high-resolution PWM capability supports precision timing in motor-control and power-conversion systems. The combination of Ethernet connectivity and deterministic control peripherals makes the device suitable for industrial automation, networking, and embedded motor-control designs.
Technically, the XMC4400 integrates an ARM Cortex-M4 processor with Infineon's peripheral set. Its high-resolution PWM and advanced timer architecture are intended to reduce the need for external timing and signal-generation components. The Ethernet MAC supports network-oriented industrial equipment, while the flash and RAM capacities provide sufficient space for control firmware, communication stacks, and application logic.
Typical applications include industrial Ethernet controllers, servo and motor drives, programmable logic controllers, industrial communication modules, and embedded automation equipment. The 120 MHz processing rate supports responsive control loops, while the Ethernet MAC provides a path to connected factory networks. System designers must still verify peripheral assignments, package dimensions, pin multiplexing, and operating limits against the complete manufacturer datasheet before schematic release.
A primary design consideration is firmware and peripheral planning. Because the LQFP-64 package exposes a finite number of pins, pin multiplexing, analog functions, debug access, clock configuration, and Ethernet connectivity must be assigned early. PCB designers should also follow the manufacturer's recommended decoupling, exposed-pad, and high-speed layout guidance before a new board is fabricated.
This product data combines the verified manufacturer and distributor information with practical comparison notes and engineering guidance that are not presented as a substitute for the complete Infineon XMC4400 datasheet. Exact electrical characteristics, pricing, lead time, lifecycle status, and package details should be confirmed against the latest manufacturer documentation and distributor records.

Typical Applications
XMC4400F64K512BAXQMA1 is suitable for 6 applications: Industrial Ethernet Motor Controller, Servo Drive and Field-Oriented Control, Programmable Logic Controller, Industrial Communication Gateway, Power Conversion Control, Robotic Control Module.
Industrial Ethernet Motor Controller
The XMC4400F64K512BAXQMA1 fits connected motor-control equipment because its 120 MHz Arm Cortex-M4 core can execute control and network software while the integrated Ethernet MAC supports industrial communication. The 150 ps high-resolution PWM capability provides precise edge timing for inverter control, and the 80 KB RAM accommodates protocol buffers and working state. A practical implementation places the MCU beside the power stage, routes PWM and control signals to the gate-driver interface, and uses the Ethernet MAC for supervisory traffic. The design must verify available package pins, PHY requirements, isolation strategy, and motor-drive safety requirements before schematic release.
Recommended
Servo Drive and Field-Oriented Control
The XMC4400F64K512BAXQMA1 is appropriate for servo drives because the 120 MHz Cortex-M4 core supports responsive field-oriented control calculations and its high-resolution PWM can generate precise motor-drive timing at 150 ps resolution. The 512 KB flash provides room for control algorithms, parameter tables, and communications firmware, while 80 KB RAM supports intermediate computations. Engineers typically use the MCU for current sampling, position processing, and PWM generation, with external gate drivers and power stages handling the motor voltage and current. Encoder interface requirements, control-loop timing, fault handling, and thermal margins must be verified against the system architecture.
Recommended
Programmable Logic Controller
The XMC4400F64K512BAXQMA1 can serve as the processing core of a compact PLC or industrial controller because it combines 120 MHz processing with 512 KB flash, 80 KB RAM, and an Ethernet MAC. The flash supports application logic and firmware, while RAM accommodates scan data, diagnostics, and communication buffers. Ethernet connectivity enables the controller to report process data or accept supervisory commands, reducing the need for a separate network processor. A practical design must allocate pins for isolated field inputs and outputs, define fail-safe states, validate scan-time requirements, and confirm that the selected package exposes all required timer, debug, and communication functions.
Recommended
Industrial Communication Gateway
The XMC4400F64K512BAXQMA1 supports an embedded industrial gateway because the integrated Ethernet MAC reduces the need for a separate Ethernet controller, while the 120 MHz core can manage protocol conversion and local control tasks. Its 512 KB flash can hold a protocol stack and application firmware, and the 80 KB RAM provides working space for frame buffers and state machines. Such a product may bridge an Ethernet network to serial or fieldbus peripherals while performing diagnostics and data preprocessing. Interface timing, DMA behavior, Ethernet PHY selection, line isolation, and sustained packet throughput should be tested at the system level because those details are not established by the distributor summaries.
Recommended
Power Conversion Control
The XMC4400F64K512BAXQMA1 is well suited to digital control of converters because its 120 MHz Cortex-M4 performance supports fast control-loop execution and its PWM resources provide deterministic switching-command generation. The high-resolution PWM capability, documented at 150 ps, can improve command granularity in applications such as DC-DC, inverter, or digitally controlled power modules. The 512 KB flash and 80 KB RAM support compensation algorithms, telemetry, and fault logging. In implementation, the MCU remains on the low-voltage control domain while external power stages switch higher energy. Designers must confirm timer resolution under the selected clock configuration and separately validate protection behavior under overload, short-circuit, and startup conditions.
Recommended
Robotic Control Module
The XMC4400F64K512BAXQMA1 fits compact robotic control modules where deterministic real-time control and wired connectivity are required in one MCU. Its 120 MHz Cortex-M4 core can coordinate encoder data, motion profiles, communications, and safety diagnostics, while 512 KB flash and 80 KB RAM provide a practical code and data budget for a single-board controller. The Ethernet MAC supports supervisory communication with a robot controller or industrial gateway. A representative design uses the MCU for real-time motion commands and network management while delegating actuator power conversion to external drivers. Cable routing, ESD protection, isolation, grounding, and pin multiplexing remain system-level design decisions.

Design Notes
Begin the LQFP-64 layout with the official Infineon footprint and pin table rather than inferring assignments from the shortened distributor description. The MCU integrates timing, communications, debug, and analog-mux functions that can conflict at 64 pins, so create a pin-allocation worksheet before routing. Confirm exposed pad, solder-mask, paste, land-pattern, and thermal requirements against the current manufacturer package drawing.
Follow the manufacturer requirements for supply voltage, decoupling, startup, and power sequencing. Place the required input and output capacitors close to their assigned pins with short return paths, and keep sensitive analog or sensor paths away from PWM and Ethernet return-current loops. Because the supplied excerpts do not include voltage limits or capacitor values, do not infer those values from generic Cortex-M4 designs; obtain them from the complete XMC4400 datasheet.
Treat Ethernet, debug, and high-speed clock routes as controlled-impedance or tightly referenced paths where applicable. Provide continuous ground beneath high-speed traces, minimize stub length, and route clocks away from PWM outputs and motor-switching nodes. Validate Ethernet magnetics or PHY layout, signal return continuity, and isolation boundaries in a system-level signal-integrity review before production release.
Do not treat similarly named Cortex-M4 devices as drop-in equivalents based only on equal frequency and flash size. The comparison candidates lack verified pin maps, peripheral assignments, interrupt-vector compatibility, and boot behavior. A true replacement requires a line-by-line pin and software comparison, followed by schematic review and hardware validation of clocks, communication, motor outputs, debug, and safety behavior.
Compliance Information
The verified search excerpts describe an industrial XMC4000 microcontroller but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed using the current Infineon product page, manufacturer declarations, or the distributor product record.
