XMC4402F64F256ABXQMA1 - 120MHz Cortex-M4 256KB Flash MCU
Référence : XMC4402F64F256ABXQMA1 ✓ ActifXMC4402F64F256ABXQMA1 Présentation
A microcontroller is a programmable system-on-chip containing a CPU core, memory, peripherals, and communication interfaces. Within the product hierarchy, this device is an ARM Cortex-M4 microcontroller, an embedded processor, an integrated circuit, and ultimately a semiconductor. The XMC4000 family is designed for industrial control systems where deterministic execution, Ethernet connectivity, and a relatively large embedded memory footprint are more important than the power density of a small sensor node.
Three headline characteristics define this part. The 120 MHz Cortex-M4 core provides 32-bit processing with integrated floating-point instruction support. The 256 kByte program flash supplies room for a bootloader, application firmware, and network configuration, while 80 kByte of SRAM supports working buffers, protocol stacks, and control data. The integrated 10/100 Ethernet interface allows the controller to participate directly in industrial Ethernet networks without a separate interface controller.
The XMC4402F64F256ABXQMA1 is identified as an industrial-grade XMC4000-series member. Its PG-LQFP-64-19 mechanical format provides 64 leads plus a thermal exposed pad, offering a larger pin count than small-outline packages and practical access to mixed-signal, communications, and digital I/O resources. The verified distributor listing confirms single-core operation, 120 MHz clocking, 256 kByte flash, and 3.3 V supply information. Additional detailed timing, peripheral, and absolute-maximum parameters must be confirmed in the manufacturer datasheet before a new design is released.
Typical applications include industrial Ethernet controllers, programmable logic controllers and automation equipment, networked motor and process controllers, industrial communication gateways, and embedded test systems. For Ethernet-connected control equipment, the combination of Cortex-M4 processing, 80 kByte SRAM, and integrated 10/100 Ethernet reduces the external component count compared with a discrete Ethernet-interface architecture. Engineers should still budget memory margin for the selected protocol stack and application firmware.
The most important design consideration is thermal management around the exposed pad. The LQFP package requires a land pattern that connects the thermal pad to a properly sized ground or thermal copper plane; a datasheet-based thermal design should verify the junction and ambient temperature limits under the maximum operating clock and Ethernet activity. The 3.3 V operating point should also be checked against every attached peripheral, level-shifting interface, and supply tolerance.
This page combines the verified Infineon and distributor specifications with practical selection guidance, pin-package details, application analysis, and same-package replacement information that is not normally consolidated on a distributor listing. It distinguishes documented facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers evaluate the XMC4402F64F256ABXQMA1 efficiently without treating unverified generic MCU specifications as fact.

Applications typiques
XMC4402F64F256ABXQMA1 convient pour 6 applications: Industrial Ethernet Controllers, Programmable Automation Controllers, Networked Motor and Process Control, Industrial Communication Gateways, Embedded Test and Measurement Equipment, Industrial Sensor Hubs.
Industrial Ethernet Controllers
The XMC4402F64F256ABXQMA1 fits industrial Ethernet controllers because its 120 MHz ARM Cortex-M4 core handles protocol processing while the integrated 10/100 Ethernet interface removes the need for a separate MAC and physical-layer controller. The 80 kByte of SRAM accommodates Ethernet frames, protocol-stack state, and supervisory tasks, and the 256 kByte flash stores the network stack, application logic, and firmware updates. A typical implementation places the MCU beside the Ethernet magnetics, line protection, and PHY components shown in the family reference design. The design advantage is reduced external interface circuitry, although the Ethernet magnetics, isolation strategy, and EMC requirements still depend on the target installation.
Recommandé
Programmable Automation Controllers
The XMC4402F64F256ABXQMA1 is appropriate for programmable automation controllers that coordinate digital inputs, outputs, counters, and communication tasks. Its 120 MHz Cortex-M4 performance provides headroom for deterministic control loops, while 256 kByte of flash holds application code and 80 kByte of SRAM supports working state and diagnostic buffers. The 64-pin PG-LQFP-64-19 package exposes more pins than compact microcontroller packages, which is useful when the controller must combine field-bus communication with conventional I/O. Firmware should still be checked against the exact peripheral mix and pin-mux table before production release.
Recommandé
Networked Motor and Process Control
The XMC4402F64F256ABXQMA1 can serve in networked motor and process-control equipment where a real-time control task and Ethernet monitoring share one microcontroller. The Cortex-M4 core executes at 120 MHz, the 256 kByte flash provides capacity for motion or control algorithms, and the 80 kByte SRAM can hold command queues and process variables. Integrated 10/100 Ethernet allows supervisory systems to exchange setpoints, status, and diagnostics over a shared industrial network. This is not a dedicated motor-driver solution, so external power stages and suitable analog sensing interfaces remain necessary. Safety-critical decisions require additional hardware and diagnostic validation beyond ordinary Ethernet communications.
Recommandé
Industrial Communication Gateways
The XMC4402F64F256ABXQMA1 suits an industrial communication gateway that must translate or aggregate real-time data over 10/100 Ethernet. Its 120 MHz single-core Cortex-M4 provides processing capacity for protocol conversion, and the 80 kByte SRAM is large enough to support concurrent buffering and network state. The 256 kByte flash capacity allows a bootloader, application firmware, configuration defaults, and protocol modules to coexist within one device. Because Ethernet PHY, transformer, surge protection, and isolation choices depend on cable length and installation class, the board should follow the manufacturer reference layout and pass its applicable EMC tests.
Recommandé
Embedded Test and Measurement Equipment
The XMC4402F64F256ABXQMA1 fits compact test and measurement equipment that combines control, data acquisition, and network reporting in one controller. The 120 MHz Cortex-M4 core can service time-critical sampling tasks and control sequences, while 256 kByte of flash and 80 kByte of SRAM separate firmware, acquisition buffers, and results. Its integrated 10/100 Ethernet interface allows measured data, configuration, and status information to be exchanged with a host computer. The exact analog measurement front end remains application-specific, and engineers should verify ADC characteristics, timing accuracy, trigger support, and calibration requirements in the XMC4402-F64x256 family documentation.
Recommandé
Industrial Sensor Hubs
The XMC4402F64F256ABXQMA1 can act as a local sensor hub for industrial installations that aggregate measurements and publish them over Ethernet. Its 80 kByte SRAM provides buffering for multiple sensor streams and protocol state, and the 256 kByte flash stores the hub firmware, calibration tables, and network configuration. The 120 MHz Cortex-M4 core leaves processing headroom for filtering and local alarms rather than merely forwarding raw data. The integrated 10/100 Ethernet interface is especially useful where a wired, reliable link is preferred over a wireless module. Sensor accuracy, input isolation, and long-cable robustness remain separate design requirements that the MCU package does not solve by itself.

Notes de conception
Treat the PG-LQFP-64-19 exposed pad as a mandatory thermal and electrical land. Follow the Infineon package drawing for exposed-pad dimensions, paste stencil, and copper connection rather than estimating from the lead count. Verified excerpts do not provide theta-JA, maximum junction temperature, or power dissipation, so no thermal-rise value is asserted here. Validate the assembled board at the highest intended clock, Ethernet traffic, and ambient temperature before production.
Place decoupling capacitors at the supply and ground pins according to the XMC4402-F64x256 reference layout, keeping each loop as short as practical. The 3.3 V supply is a verified identity parameter, but tolerance, transient response, and startup sequencing are not included in the supplied excerpts. Route sensitive clock and Ethernet differential pairs on a controlled-impedance stack-up, maintain continuous return paths, and keep switching or high-current paths away from the MCU and PHY sections.
Do not assign the Ethernet PHY, magnetics, or isolation network without checking the manufacturer reference schematic because the MCU’s integrated 10/100 Ethernet capability does not by itself specify every external network component. Confirm which PHY and magnetics arrangement the family documentation supports, then preserve isolation spacing, surge-current paths, and creepage and clearance required by the installation class. Verify exposed-pad connectivity in the final Gerber and assembly drawings.
Avoid assuming that every 64-pin Cortex-M4 MCU is interchangeable with the XMC4402F64F256ABXQMA1. Pin multiplexing, peripheral instances, analog functions, debug signals, clock architecture, and Ethernet PHY integration must match the selected board. Likewise, do not substitute a 512 kByte-flash XMC4400 solely because its ordering code also ends in a 64-pin option; the verified comparison result indicates a different memory configuration, requiring a complete manufacturer comparison.
Informations de conformité
The supplied verified excerpts identify the device as an industrial XMC4000-series microcontroller but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm these declarations on the current Infineon product and material-compliance pages.
