MPN: XMC4400F64F256ABXQMA1 ✓ ActiveXMC4400F64F256ABXQMA1 Overview
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and communication interfaces on one device. Within the product hierarchy, the XMC4400 is an ARM Cortex-M4 MCU, an embedded processor within the XMC4000 family. It combines real-time control performance with industrial peripherals, allowing one device to supervise sensors, execute control algorithms, and exchange data through Ethernet or serial interfaces.
The principal features visible in the ordering information include a 120 MHz Cortex-M4 core, 256 KB of flash memory, a 3.3 V operating supply, and an Ethernet MAC. The 32-bit RISC architecture supports compact, efficient embedded software, while the integrated Ethernet MAC provides a dedicated path for network-connected industrial equipment. The LQFP-64 exposed-pad package also provides a substantial underside thermal and ground connection for designs requiring improved electrical and thermal performance.
The XMC4400F64F256ABXQMA1 belongs to the industrial XMC4000 product class, making it suitable for control platforms that require both deterministic operation and communications. The 256 KB flash capacity supports embedded boot code, configuration data, and application firmware in a single-controller design. Its 120 MHz operating rate provides additional timing margin for protocol processing, digital signal handling, and supervisory control tasks.
Typical applications include industrial Ethernet controllers, programmable automation equipment, motor and motion-control systems, connected sensor gateways, industrial communication equipment, and embedded measurement systems. In these systems, the MCU can execute real-time control loops while the Ethernet MAC manages networked communication without requiring a separate network controller.
PCB implementation requires correct assignment of the 3.3 V supply, decoupling, clock, reset, debug, and communication signals according to the manufacturer pin-description table. The exposed pad should be connected to the intended ground plane and thermally sized for the final board stack-up. Firmware should also validate operating limits, peripheral clock configurations, and Ethernet physical-layer requirements before field deployment.
This page combines the manufacturer ordering information with practical application guidance, package considerations, and a parameter-focused comparison with members of the XMC4400 family. These engineering details help designers distinguish flash-density or ordering-code changes from changes that require PCB or firmware modification.

Typical Applications
XMC4400F64F256ABXQMA1 is suitable for 6 applications: Industrial Ethernet Control, Motor and Motion Control, Connected Sensor Gateway, Programmable Automation Controller, Embedded Measurement System, Industrial Communication Equipment.
Industrial Ethernet Control
The XMC4400F64F256ABXQMA1 fits industrial Ethernet control platforms because its Ethernet MAC and 120 MHz Cortex-M4 core can manage network traffic while executing deterministic control functions. The 256 KB flash provides space for protocol handlers, configuration, diagnostics, and application code. Designers should use the manufacturer Ethernet reference circuitry, provide the required physical-layer interface, isolate external network connections where necessary, and preserve high-speed differential-routing geometry. The main benefit is consolidating communications and real-time control into one 64-pin device; the primary implementation constraint is careful validation of PHY, clock, reset, and Ethernet timing.
Recommended
Motor and Motion Control
The XMC4400F64F256ABXQMA1 is appropriate for motor-control and motion-control subsystems that require a high-performance real-time core alongside industrial communications. Its 120 MHz Cortex-M4 performance supports control-loop execution, state-machine management, and communication protocol handling, while the Ethernet MAC enables supervisory control or motion-network connectivity. The 256 KB flash capacity can hold control firmware and calibration parameters. Board design should isolate noisy power paths, provide low-impedance grounding, and time digital interfaces to the motor-drive circuitry. Verify timer, PWM, and analog-adapter characteristics against the exact XMC4400 derivative before finalizing the control architecture.
Recommended
Connected Sensor Gateway
A connected sensor gateway benefits from the XMC4400F64F256ABXQMA1 because its Cortex-M4 core can normalize measurements and manage local control tasks while the Ethernet MAC forwards data to a supervisory network. The 256 KB flash supports gateway firmware, data structures, and configuration, and the 64-pin LQFP package simplifies use on conventional industrial controller boards. Use the manufacturer pin descriptions to assign serial sensors, digital inputs, and communication interfaces. Signal conditioning, surge protection, and isolation should be designed around the actual sensor environment rather than assumed to be part of the MCU. Ethernet magnetic-component placement and controlled-impedance routing are especially important for reliable field operation.
Recommended
Programmable Automation Controller
The XMC4400F64F256ABXQMA1 supports programmable automation controllers that combine deterministic machine control with Ethernet-based supervisory communication. Its 120 MHz Cortex-M4 core provides timing margin for sequencing, diagnostics, and communication, while 256 KB of flash accommodates application firmware and nonvolatile configuration. The integrated Ethernet MAC allows the controller to report state, accept commands, and participate in industrial network management. Use exposed-pad copper to improve heat spreading, place decoupling close to supply pins, and isolate analog measurement paths from Ethernet and switching circuitry. Firmware validation should cover startup sequencing, network recovery, fault handling, and peripheral timing under the worst expected bus load.
Recommended
Embedded Measurement System
The XMC4400F64F256ABXQMA1 can serve as the control processor in an embedded measurement system where local acquisition, signal processing, and network reporting must coexist. The 120 MHz Cortex-M4 core is suitable for digital filtering and supervisory algorithms, and the 256 KB flash supports application code and calibration records. Ethernet MAC integration simplifies connected instrumentation, but the analog front end remains a separate design responsibility. Keep sensor inputs away from switching nodes and high-speed Ethernet traces, use a controlled grounding strategy, and confirm the selected derivative’s analog peripherals and electrical limits in the manufacturer documentation. This approach supports compact industrial test and monitoring equipment without a separate communications processor.
Recommended
Industrial Communication Equipment
The XMC4400F64F256ABXQMA1 fits industrial communication equipment that must translate between local control functions and an Ethernet network. Its 120 MHz Cortex-M4 core can process protocol stacks and maintain real-time peripheral operation, while the 256 KB flash provides sufficient room for firmware and configuration. The 64-pin exposed-pad LQFP package supports conventional surface-mount assembly and a direct ground connection. For production reliability, implement the reference network interface, maintain suitable creepage and clearance, validate magnetics and PHY placement, and test operation across the intended temperature range. The integrated MAC reduces system complexity, but it does not remove the need for qualified external network circuitry.

Key Differentiators
- Exact manufacturer order code identifies the required industrial configuration (vs XMC4400-F64F256-BA)

- Largest listed family flash option (vs XMC4400-F256F256-BA)
Design Notes
Use a 3.3 V supply and follow the manufacturer’s recommended decoupling topology. Place the required supply capacitors at the associated power pins with short, low-inductance connections, and provide clean return paths to the exposed pad and ground structure. Avoid routing switching-node or high-current motor-return currents beneath the controller. Confirm the final voltage tolerance and operating current from the exact electrical-characteristics table before releasing the power design.
The PG-LQFP-64 exposed pad is an important electrical and thermal connection, not an unused mechanical feature. Connect it to the intended ground plane and preserve as much uninterrupted copper as practical. Thermal performance depends on the board stack-up, copper area, airflow, and adjacent heat sources. Validate the assembled design at the highest expected ambient temperature because industrial control systems may place the MCU near switching regulators or power stages.
Assign clocks, reset, debug, Ethernet, and serial interfaces strictly from the Infineon pin-description table. Keep high-speed Ethernet traces short, length-matched as required, and over a continuous reference plane, with magnetics and PHY placement based on the reference design. Separate sensitive analog or sensor inputs from switching nodes. Review every exposed-pad and supply connection against the package drawing to prevent footprint errors that can compromise both operation and assembly yield.
Do not treat the base family name and the complete order code as interchangeable without checking the Infineon ordering table. Confirm flash density, package, temperature grade, delivery form, and any derivative-specific deviations before substitution. Review the relevant errata sheet alongside the datasheet because the family document describes a superset of devices. Firmware should also be regression-tested because changes in memory configuration, peripheral availability, or errata can alter startup and interrupt behavior.
