XMC4402F64F256BAXQMA1 - 120MHz Cortex-M4 MCU | Infineon
MPN: XMC4402F64F256BAXQMA1 ✓ ActiveXMC4402F64F256BAXQMA1 Overview
An industrial microcontroller is a semiconductor device designed to execute embedded control logic, communicate with external equipment, and operate reliably in industrial environments. The XMC4000 family combines the Arm Cortex-M4 processor architecture with Ethernet, timers, analog and digital interfaces, and embedded flash and SRAM. This places it within the hierarchy of embedded processor, microcontroller, industrial control IC, and semiconductor.
The XMC4402F64F256BAXQMA1 provides 256 kByte of flash for program storage and 80 kByte of SRAM for working memory. Its processor operates at up to 120 MHz, while the high-resolution PWM unit offers 150 ps resolution for precision timing and motor-control tasks. Integrated 10/100 Ethernet support reduces the component count required for network-connected industrial equipment.
The Arm Cortex-M4 architecture supports efficient real-time control while retaining a broad embedded software ecosystem. Peripheral resources such as high-resolution PWM, communication interfaces, and Ethernet position the device for motor control, industrial networking, automation controllers, and connected embedded systems. The 150 ps PWM resolution is particularly useful when the application depends on accurate edge positioning rather than only a conventional timer period.
Typical uses include EtherCAT or Ethernet-based factory automation equipment, servo and motor-control systems, industrial communication gateways, programmable logic controllers, and networked sensor-control modules. For designs requiring a 3.3 V operating rail, the device can support a compact controller architecture while combining local real-time processing with Ethernet connectivity.
Designers should follow the manufacturer’s pin, power, decoupling, clock, and exposed-pad guidance when laying out the PG-LQFP-100-25 package. The exposed thermal pad requires a properly designed land pattern and thermal-via arrangement if heat must be removed from the device. Firmware should also validate the selected clock, Ethernet physical interface, and peripheral pin multiplexing before production release.
This product record combines the manufacturer’s XMC4402-F64F256-BA characteristics with orderable MPN context, useful application guidance, and explicit design cautions. It helps engineers distinguish confirmed memory, connectivity, package, and timing attributes from details that must be checked in the manufacturer datasheet before schematic or PCB signoff.

Typical Applications
XMC4402F64F256BAXQMA1 is suitable for 6 applications: Industrial Ethernet Automation Controller, Servo Motor Control, EtherCAT Industrial Control, Programmable Logic Controller, Industrial Communication Gateway, Precision Power Conversion Controller.
Industrial Ethernet Automation Controller
XMC4402F64F256BAXQMA1 fits industrial Ethernet automation controllers because it combines an Arm Cortex-M4 core operating up to 120 MHz with integrated 10/100 Ethernet connectivity. The controller can execute real-time automation logic locally while exchanging commands, status, and diagnostic data over Ethernet, reducing latency compared with a separate network processor. Its 256 kByte of flash supports embedded control firmware, while 80 kByte of SRAM accommodates communication buffers and state variables. The 150 ps PWM resolution is also useful when the controller coordinates precise actuators or sampling events.
Servo Motor Control
The XMC4402F64F256BAXQMA1 is appropriate for compact servo-control systems that combine deterministic timing with Ethernet-based commissioning or supervisory control. Its high-resolution PWM output provides 150 ps edge-resolution capability, supporting precise current or position-control loops, while the 120 MHz Cortex-M4 core can execute control algorithms and diagnostics. The 80 kByte of SRAM provides working memory for motion state, and 256 kByte of flash stores application code. Designers should still validate PWM channels, analog feedback paths, and power-stage timing against the manufacturer pin and timing documentation.
EtherCAT Industrial Control
XMC4402F64F256BAXQMA1 can support timing-sensitive industrial control equipment built around Ethernet communications, including EtherCAT-oriented control electronics. The 120 MHz Arm Cortex-M4 core provides real-time processing, the high-resolution PWM unit offers 150 ps resolution for deterministic signal generation, and 10/100 Ethernet supports standard network interfaces. Designers should confirm the required Ethernet PHY, isolation, magnetic-interface components, and protocol-specific hardware support in the manufacturer documentation. This device is best treated as the real-time controller element rather than a complete network interface solution.
Programmable Logic Controller
XMC4402F64F256BAXQMA1 suits compact PLC and embedded automation modules that need local control without a separate host processor. Its 256 kByte of flash accommodates firmware, configuration tables, and communication routines, while 80 kByte of SRAM supports cyclic state, diagnostics, and I/O buffering. Ethernet connectivity enables engineering access, status reporting, and remote supervision, and the 120 MHz core provides headroom for deterministic control loops. Before schematic release, engineers should verify the required analog and digital I/O count, peripheral multiplexing, and memory map against the exact package data.
Industrial Communication Gateway
XMC4402F64F256BAXQMA1 can be used in an industrial communication gateway that connects embedded equipment to a 10/100 Ethernet network while performing local protocol conversion or supervisory logic. Its 120 MHz Cortex-M4 core handles network tasks and application processing, while 256 kByte of flash and 80 kByte of SRAM provide space for protocol stacks and buffered data. The dedicated 150 ps PWM resolution is useful for chassis timing or synchronized control outputs. A practical design also needs an appropriate Ethernet PHY, isolation strategy, connectors, and surge protection determined by the installation environment.
Precision Power Conversion Controller
XMC4402F64F256BAXQMA1 is suitable for supervisory control in precision power-conversion systems where deterministic switching timing and fast control computation are important. The 150 ps high-resolution PWM capability allows highly precise edge placement, while the 120 MHz processor can execute current control, fault handling, and supervisory functions. The 80 kByte of SRAM supports control variables and sampled data, and the 256 kByte of flash stores control code. Power-stage gate drivers, current sensing, compensation settings, and safety behavior must be designed and validated separately at the system level.

Key Differentiators
- Integrated 10/100 Ethernet reduces the need for a separate network controller in connected industrial equipment (vs XMC4402F64K256BAXQMA1)
- High-resolution PWM supports more precise edge placement in timing-sensitive control designs (vs XMC4402F64K256BAXQMA1)
- Large embedded memory supports control firmware and communication workloads in one device (vs XMC4402F64K256BAXQMA1)
Design Notes
Follow the manufacturer’s PG-LQFP-100-25 footprint and exposed-pad layout exactly. Preserve short, symmetric connections to the supply and ground pins, place decoupling capacitors close to their assigned pins, and implement the recommended thermal-via pattern beneath the exposed pad. Validate clearances and annular rings against the PCB fabricator’s current capability before release.
Design the 3.3 V supply path for both digital and analog load requirements identified in the manufacturer documentation. Use the prescribed bypass capacitance at supply pins and confirm startup, brownout, and I/O voltage-domain constraints. Do not assume that every peripheral operates from the nominal 3.3 V rail without checking its specified input limits.
Ethernet signal integrity depends on a correctly designed PHY interface, controlled-impedance routing, suitable return paths, and compliant magnetics or isolation components. Keep high-current switching paths and crystal or clock traces away from sensitive nets. Review the manufacturer reference design and Ethernet interface guidance before finalizing trace geometry.
Do not substitute XMC4402F64K256BAXQMA1 as a drop-in alternative: its documented ordering information uses PG-LQFP-64-19 rather than the target PG-LQFP-100-25 package. Likewise, treat XMC4402-F64F256-BA as the family designation rather than a separate interchangeable orderable MPN, and verify every package and qualification suffix before procurement.
Use the manufacturer’s thermal data to select the exposed-pad copper area, via count, and board construction for the expected ambient temperature and switching activity. Estimated: the actual junction rise depends on the power dissipation, board copper area, via arrangement, and ambient conditions; obtain those values from the datasheet and application guidance rather than assuming the package rating applies without board-specific calculation.
