MPN: XMC4400F64K256BAXQMA1 ✓ ActiveXMC4400F64K256BAXQMA1 Overview
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile data memory, and peripherals into one device. The XMC4400 belongs to the XMC4000 family of 32-bit Arm Cortex-M4 microcontrollers, combining real-time control capability with Ethernet communications and a high-resolution PWM architecture. Its memory hierarchy supports connected industrial equipment, distributed control nodes, and compact embedded automation systems.
Key features include a 120 MHz Arm Cortex-M4 processor, 256 KB flash, 80 KB SRAM, 10/100 Ethernet, and a high-resolution PWM unit with 150 ps resolution. The 64-pin LQFP package provides a practical surface-mount form factor for industrial controller designs. A 3.3 V operating supply and single-core 32-bit architecture simplify system integration while supporting deterministic control and communication workloads.
The XMC4400 architecture uses an Arm Cortex-M4 processor with integrated digital signal processing capabilities. Its high-resolution PWM unit supports accurate timing, motor-drive modulation, and power conversion control, while the Ethernet interface enables network-connected industrial equipment. The manufacturer describes the device as an industrial MCU and identifies the XMC4400-F64K256-BA as having 256 KB flash, 80 KB SRAM, and 10/100 Ethernet capability.
Typical applications include industrial Ethernet controllers, programmable automation equipment, motor-control systems, power-conversion controllers, sensor-hub platforms, and embedded network gateways. Its combination of real-time processing, Ethernet connectivity, and precise PWM timing makes it appropriate for machinery that must execute control algorithms while exchanging data with supervisory systems.
Designers should treat all 64 package pins as electrically significant and follow the complete pin-description and package information in the manufacturer datasheet. For mixed-signal or high-speed Ethernet layouts, preserve the recommended separation, grounding, and decoupling arrangement. Firmware validation should also include startup behavior, Ethernet timing, peripheral pin multiplexing, and worst-case operating conditions.

Typical Applications
XMC4400F64K256BAXQMA1 is suitable for 6 applications: Industrial Ethernet Controllers, Motor Drive and PWM Control, Programmable Automation Equipment, Embedded Network Gateways, Sensor and Condition-Monitoring Hubs, Power Conversion and Energy Control.
Industrial Ethernet Controllers
The XMC4400F64K256BAXQMA1 fits industrial Ethernet controllers that combine network communication with deterministic control. Its 120 MHz Arm Cortex-M4 processor supports protocol handling and control-loop execution, while the Infineon manufacturer page identifies 10/100 Ethernet, 256 KB flash, and 80 KB SRAM. A typical design places the MCU beside an Ethernet PHY and connects it to automation equipment through isolated or non-isolated differential pairs. The 150 ps high-resolution PWM capability can also coordinate sampling or actuator timing with network events, reducing reliance on separate timing hardware.
Recommended
Motor Drive and PWM Control
The XMC4400F64K256BAXQMA1 is well suited to motor-control and digital power-conversion systems requiring precise switching timing. The Infineon manufacturer datasheet identifies a high-resolution PWM unit with 150 ps resolution, while the 120 MHz Cortex-M4 core executes control algorithms and supervisory logic. In an inverter or motor controller, the MCU can generate complementary switching commands, capture timing events, and manage current or speed control. Board design must keep switching-node signals compact, provide clean gate-driver supply rails, and provide a common reference between the MCU and power stage.
Recommended
Programmable Automation Equipment
The XMC4400F64K256BAXQMA1 supports compact programmable automation equipment where real-time control, networking, and moderate memory are required. Its 256 KB flash can hold application firmware, communications stacks, and parameter tables, while 80 KB SRAM supports working state and diagnostic buffers. At 120 MHz, the single-core Cortex-M4 processor can coordinate digital inputs, outputs, counters, and communications. The 64-pin PG-LQFP-64-19 package also offers a manageable assembly option for industrial controller boards that need more I/O than a small microcontroller package can provide.
Recommended
Embedded Network Gateways
The XMC4400F64K256BAXQMA1 can serve as the control and communications processor in a small embedded gateway. Its 10/100 Ethernet interface supports local network connectivity, while the Arm Cortex-M4 core and 80 KB SRAM are sufficient for protocol translation, data filtering, status reporting, and supervisory logic. The 3.3 V supply simplifies integration with industrial communication interfaces, and the 256 KB flash capacity can hold networking code plus application firmware. For gateway deployments, use isolation and surge protection according to the installation environment, and verify link behavior during firmware upgrades and network disruptions.
Recommended
Sensor and Condition-Monitoring Hubs
The XMC4400F64K256BAXQMA1 can act as a local sensor-hub controller for machinery and equipment that combines analog measurements with communications. Its 120 MHz processor supports digital filtering, diagnostics, and concurrent network tasks, while 256 KB flash and 80 KB SRAM provide room for calibration tables, operating counters, and cached status information. The microcontroller’s extensive pin set allows connection of sensors, digital inputs, communication transceivers, and local displays. Designers should partition analog and digital return paths, follow the datasheet grounding concept, and validate filtering against the bandwidth and noise requirements of each sensor.
Recommended
Power Conversion and Energy Control
The XMC4400F64K256BAXQMA1 is appropriate for digitally controlled power-conversion equipment where fast PWM edges and network supervision are valuable. Its 150 ps high-resolution PWM feature improves control of switch timing, while the 120 MHz Cortex-M4 core can execute current-mode or voltage-mode control loops and monitor system state. The device also provides 10/100 Ethernet for supervisory control, diagnostics, and remote configuration. Layout is critical: isolate high-current switching paths from sensitive analog and clock nets, use local bulk and high-frequency decoupling, and verify dead time, fault shutdown, and thermal conditions across the complete operating range.

Design Notes
Place every supply bypass capacitor directly beside its associated VDD or VDDIO pin, using the shortest possible ground return. The Infineon manufacturer datasheet states that VSS, VSSA, and VSSO share a common ground potential, so their return paths must converge cleanly at the device. Keep high-current Ethernet magnetics and switching-power paths away from oscillator and analog inputs. Route differential Ethernet pairs as a controlled-impedance pair with symmetric geometry and continuous reference planes.
Treat oscillator, analog, Ethernet, and digital interfaces as separate layout domains. Keep the crystal or clock path short, preserve the ground reference beneath it, and avoid routing it beside Ethernet and high-voltage switching nodes. Validate the final stack-up and controlled-impedance geometry for the selected Ethernet PHY. For motor or converter designs, place the MCU and gate-driver interface away from power-switching copper and use a deliberate common-ground strategy that follows the manufacturer reference layout.
A same-package replacement does not automatically mean firmware-compatible. Review the device identity, flash partition, linker script, SRAM usage, peripheral availability, pin multiplexing, clock setup, startup vector table, and temperature-grade requirements before changing the ordering code. The high-resolution PWM and Ethernet functions may be used differently by density derivatives. Run the existing firmware unchanged first, then repeat boundary, fault, and communication tests on the selected device.
Compliance Information
The Infineon product information identifies the XMC4400-F64K256-BA as an industrial MCU, while a distributor listing identifies the exact ordering code as automotive temperature grade. Explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals statements require manufacturer confirmation.
