XMC4104F64K64BAXQMA1 - 80MHz Cortex-M4 MCU | Infineon
MPN: XMC4104F64K64BAXQMA1 ✓ ActiveXMC4104F64K64BAXQMA1 Overview
An ARM Cortex-M4 microcontroller is a 32-bit embedded processor designed for deterministic control systems. Positioned within the hierarchy of microcontroller, embedded processor, and semiconductor, it executes firmware while integrating timers, communication interfaces, analog functions, and general-purpose input/output on one device. The XMC4104F64K64BAXQMA1 is therefore more than a general CPU: it provides an integrated platform for industrial motor, timer, communication, and mixed-signal control designs.
The principal features are an 80 MHz Cortex-M4 core, 64 KB flash, 20 KB SRAM, and operation from -40°C to +125°C. These ratings support compact embedded programs, deterministic peripheral operation, and deployment across industrial temperature ranges. Its industrial ordering designation, BA package, 64 KB memory configuration, and exposed-pad LQFP construction distinguish it from general-purpose 64-pin microcontrollers with different memory maps or peripheral mixes.
Technically, the XMC4000 architecture targets applications combining high-resolution timers with field-bus communications and mixed-signal control. The Cortex-M4 processing capability provides sufficient throughput for communication stacks and supervisory logic, while 20 KB of SRAM supports working data and interrupt context. Because its exact peripheral assignments, clock-tree limits, electrical characteristics, and pin functions require the manufacturer documentation, designers should consult the Infineon product documentation before finalizing a board.
Typical applications include industrial timer and motion-control modules, CAN-connected factory equipment, LIN-based automotive or industrial subsystems, USB service interfaces, and mixed-signal controllers. The -40°C to +125°C range makes the device suitable for industrial environments, while its exposed-pad LQFP package supports PCB-level heat dissipation when the operating conditions require it.
The primary design consideration is footprint and firmware verification: the exact PG-LQFP-64-19 land pattern, exposed-pad connection, pin multiplexing, and peripheral resources must match the intended schematic and PCB. A replacement should not be assumed compatible merely because it uses a 64-pin package; memory size, peripheral mapping, clock behavior, and exposed-pad requirements must all be checked.
This page consolidates the verified manufacturer and distributor information for the XMC4104F64K64BAXQMA1, adds practical sourcing and comparison guidance, and clearly separates confirmed specifications from data that still requires confirmation from the complete Infineon datasheet.

Typical Applications
XMC4104F64K64BAXQMA1 is suitable for 6 applications: Industrial Timer and Motion Control, CAN-Connected Factory Equipment, LIN Subnetwork Controller, USB Service and Configuration Interface, Mixed-Signal Data Acquisition Module, Industrial Gateway and Communications Hub.
Industrial Timer and Motion Control
The XMC4104F64K64BAXQMA1 fits timer-driven industrial control because its 80 MHz ARM Cortex-M4 core provides processing headroom while 20 KB of SRAM supports real-time working data and interrupt handling. The -40°C to +125°C rating also aligns with factory equipment operating across extended temperature ranges. It can coordinate timing sequences, supervisory logic, and communication tasks around a motor-control or actuator-control subsystem. The 64 KB flash budget provides space for the application firmware and control tables, although the complete timer channels and PWM resources must be confirmed in the official datasheet before assigning them.
Recommended
CAN-Connected Factory Equipment
The XMC4104F64K64BAXQMA1 is suitable for CAN-connected factory modules because it combines an 80 MHz Cortex-M4 processor, 20 KB of SRAM, and CAN connectivity in one 64-pin industrial MCU. A design can use the core for local control and diagnostics while a CAN interface distributes operating data across a machine or cell network. Its 64 KB flash capacity is appropriate for compact protocol handlers and supervisory code, while the -40°C to +125°C specification supports industrial environments. Exact transceiver needs, CAN feature set, and I/O mapping remain subject to verification against the complete Infineon documentation.
Recommended
LIN Subnetwork Controller
The XMC4104F64K64BAXQMA1 can serve as a LIN-oriented controller where an embedded system needs local logic combined with LIN communication. Its 80 MHz Cortex-M4 core is substantially more capable than a simple communications-only controller and can supervise diagnostics, actuator logic, and higher-level CAN or USB tasks when present. The 20 KB SRAM provides working space for protocol and application data, and the 64 KB flash supports a consolidated firmware image. Because the verified records do not enumerate the LIN transceiver interface or every alternate function, the design must use the official pin and peripheral documentation before final schematic assignment.
Recommended
USB Service and Configuration Interface
The XMC4104F64K64BAXQMA1 supports USB-connected service, configuration, or data-acquisition modules by integrating USB with a general-purpose Cortex-M4 core and 20 KB of SRAM. Firmware can handle USB traffic concurrently with timers, communications, and supervisory functions, while 64 KB of flash holds application and interface code. This combination is useful for compact industrial modules that need a service interface without adding a separate communications processor. USB electrical requirements, supported device or host roles, endpoint resources, and shared-pin tradeoffs must be confirmed from the complete manufacturer datasheet before layout is released.
Recommended
Mixed-Signal Data Acquisition Module
The XMC4104F64K64BAXQMA1 is appropriate for a mixed-signal acquisition module that must coordinate analog measurement channels, timers, and communications in a compact controller. Its 80 MHz ARM Cortex-M4 core can execute filtering and supervisory routines, while 20 KB of SRAM accommodates temporary measurement and control data. The -40°C to +125°C range supports industrial instrumentation, and 64 KB of flash can contain the control and communication firmware. The exact ADC characteristics, analog-pin count, sample-rate limits, and peripheral conflicts are not included in the supplied data and must be obtained from the official XMC4100/4200-series documentation.
Recommended
Industrial Gateway and Communications Hub
The XMC4104F64K64BAXQMA1 can be evaluated as a compact communications hub for equipment that bridges CAN, LIN, and USB-facing functions. The Cortex-M4 core at 80 MHz provides capacity for protocol handling and application logic, while 20 KB of SRAM supports active communication buffers and 64 KB of flash accommodates gateway firmware. Its 64-pin PG-LQFP-64-19 construction provides a substantial pin count for communications and control signals, and the exposed pad supports heat spreading where required. Engineers should verify all peripheral instances, interrupt priorities, and alternate-function assignments before treating it as a complete gateway platform.

Design Notes
Treat the exposed pad as a functional thermal and electrical feature of the PG-LQFP-64-19 package. The verified records confirm that the package has an exposed pad, but they do not provide its recommended net assignment, dimensions, or thermal resistance. Before layout, obtain the official Infineon package drawing and land pattern, then provide the specified copper and thermal-via arrangement. Do not infer those details from a generic LQFP-64 footprint because pad geometry and solder-mask requirements can affect assembly reliability.
Use the manufacturer-approved PG-LQFP-64-19 footprint rather than selecting a footprint solely by pin count. Verify pin numbering, pad dimensions, exposed-pad geometry, solder-mask opening, and paste pattern against the official Infineon package drawing. The supplied sources confirm the 64-pin package and exposed pad but do not provide the land pattern itself, so a generic LQFP library entry should not be accepted without manufacturer-level dimensional review.
Plan the 3.3 V power architecture from the complete electrical specifications in the manufacturer datasheet. Confirm the exact operating-voltage limits, external decoupling requirements, internal regulator behavior, and input-voltage tolerance for the selected ordering code. Place required input and output capacitors at the associated pins using the datasheet layout guidance, and keep high-current return paths compact. Because the supplied data does not include capacitance values or ESR limits, those values must not be guessed during schematic review.
Do not treat a 64-LQFP alternative as automatically drop-in merely because its pin count matches. For the XMC4108F64K64BAXQMA1 candidate, verify alternate functions, timer channels, analog inputs, communication instances, interrupt routing, clock configuration, memory organization, and exposed-pad requirements. Firmware may also depend on device-specific headers and startup configuration. A hardware-fit check without a complete pin and peripheral comparison can produce a board that powers up but lacks required functions.
Compliance Information
The verified records identify the device as an industrial microcontroller and provide a -40°C to +125°C temperature rating, but they do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance.
