XMC4400F100K512BAXQMA1 - 120MHz Cortex-M4 MCU | Infineon
MPN: XMC4400F100K512BAXQMA1 ✓ ActiveXMC4400F100K512BAXQMA1 Overview
An Arm Cortex-M4 microcontroller is a 32-bit embedded processor based on the Armv7E-M architecture. It combines a real-time processing core with timers, communication peripherals, memory interfaces, and GPIO in one integrated circuit. Within the product hierarchy, the XMC4400 is a microcontroller, embedded processor, and semiconductor designed for industrial control systems where deterministic peripherals and network connectivity are more important than general-purpose computing performance.
Principal features include 120 MHz processing, 512 kB of flash memory, 10/100 Ethernet MAC capability, and a high-resolution PWM unit with 150 ps resolution. The fine PWM resolution is especially useful in digital power conversion, where precise duty-cycle control can improve regulation behavior and reduce harmonic distortion. The integrated communication and timing resources also reduce the need for external interface components in industrial Ethernet and automation equipment.
The XMC4000 peripheral set includes dedicated digital power conversion resources and multiple high-speed timer inputs. This combination allows the microcontroller to control switched-mode power stages while managing communications and supervisory functions. The 100-pin LQFP package exposes substantially more I/O than smaller MCU packages, allowing dedicated signals for power-control loops, communications, diagnostics, and machine interfaces while preserving an exposed thermal pad for heat spreading.
Typical applications include industrial Ethernet controllers, programmable logic controllers, digital power supplies, motor-control and inverter equipment, factory automation nodes, industrial communication gateways, and embedded data-acquisition systems. The 10/100 Ethernet capability is particularly suitable for legacy industrial networks, while the 150 ps PWM resolution supports high-resolution power-conversion control.
PCB design should prioritize a low-impedance ground plane, careful routing of power-stage signals, and effective decoupling around the 3.3 V supply pins. The exposed pad must be connected to the appropriate ground-plane area according to the manufacturer’s land-pattern guidance. Ethernet traces require controlled topology and return-path continuity to minimize reflections and susceptibility to common-mode noise.
This product page combines manufacturer specifications with practical design guidance, packaging information, and pin-compatible alternatives for engineering evaluation. It helps designers assess whether the 120 MHz Cortex-M4 core, 512 kB flash, 10/100 Ethernet support, 150 ps PWM resolution, and PG-LQFP-100 footprint fit an industrial control or digital power-conversion design before committing the exact ordering code to a BOM.

Key Differentiators
- Higher flash capacity than reduced-memory XMC4000 alternatives (vs XMC4400F100K128BAXQMA1)
- Substantially more code and configuration storage than the 256 kB derivative (vs XMC4400F100K256BAXQMA1)
- Identified closest ordering-code candidate (vs XMC4400F100K512ABXQMA1)
- Full manufacturer ordering designation for the specified configuration (vs XMC4400-F100K512-BA)
Design Notes
Use the manufacturer’s PG-LQFP-100 land pattern and exposed-pad geometry exactly. Connect the exposed pad to the ground plane through the prescribed thermal-via arrangement, maintaining short and symmetric return paths for every supply connection. Place input and bulk-decoupling capacitors close to their associated pins. Confirm clearances for the 3.3 V rail and all external interface signals against the final industrial-board insulation requirements.
Route 10/100 Ethernet differential pairs as a controlled-impedance, tightly coupled pair with a continuous reference plane. Avoid plane splits, test-point stubs, and right-angle routing beneath the pair. Respect the receive and transmit pair geometry specified for the selected Ethernet PHY and magnetics. Add common-mode filtering close to the connector while following the magnetics and PHY vendor guidance on component placement.
Separate the digital control section from analog sensing and power-converter routing. Place the MCU, decouplers, and support components before sensitive feedback networks, and route high-current switching paths away from the 150 ps PWM and Ethernet signals. Maintain a coherent ground strategy with low-impedance connections between the exposed pad, supply return, and analog reference. Avoid using the exposed pad as a general-purpose signal route.
Do not substitute a lower-flash XMC4000 derivative without checking linker output, bootloader assumptions, calibration tables, and protocol stacks. The 256 kB option has 256 kB less flash than the target, while the 128 kB option has 384 kB less. Firmware development should also avoid depending on a particular BA, AB, F, or K ordering-code interpretation until the final manufacturer ordering designation has been confirmed.
Compliance Information
The device is identified by Infineon as an industrial microcontroller. Specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations require confirmation from the exact ordering documentation.
