XMC4100F64K128BAXQMA1 - 80MHz Cortex-M4 MCU | Infineon
MPN: XMC4100F64K128BAXQMA1 ✓ ActiveXMC4100F64K128BAXQMA1 Overview
A microcontroller is a programmable system-on-chip that integrates a processor core, nonvolatile program memory, volatile data memory, peripherals, and interrupt control into one device. The XMC4100 belongs to Infineon's XMC4000 family, where the ARM Cortex-M4 core is used in the hierarchy Cortex-M4 processor → 32-bit microcontroller → embedded microcontroller → industrial semiconductor. Its combination of 128 KB flash, 20 KB SRAM, and 80 MHz execution speed provides a practical balance between firmware capacity, real-time processing, and package size.
Key features include the 80 MHz ARM Cortex-M4 processor core, 128 KB flash organized as 128K × 8, and 20 KB SRAM. On-chip resources include DMA for efficient data movement, I2S for digital audio data transfer, PWM generation for motor or power-converter control, an LED-control peripheral, a power-on reset function, and a watchdog timer. These integrated blocks reduce external component requirements and allow control software to service multiple deterministic tasks.
The 64-pin LQFP package provides conventional leaded soldering access while supporting a board footprint identified as PG-LQFP-64-19. The industrial XMC4100-F64K128-BA device variant is explicitly presented by Infineon as an industrial ARM Cortex-M4 microcontroller. Its 80 MHz core is suitable for sampled control loops and protocol handling, while DMA reduces processor intervention when transferring data between memory and serial peripherals.
Typical uses include industrial motor controllers, distributed automation nodes, digital audio interfaces, LED control systems, and embedded communications equipment. For motor-control designs, the PWM and DMA resources can support deterministic actuator timing, while the I2S interface can serve synchronous digital-audio paths. The 128 KB flash region accommodates control code, configuration tables, and field-update routines, while 20 KB SRAM supports working state and communication buffers.
When designing a board, validate the exact package pin mapping, exposed-pad connection, decoupling requirements, clock configuration, and peripheral instance assignments against the manufacturer datasheet. Firmware should include watchdog servicing, controlled reset behavior, and graceful handling of communications loss. Production programming and lifecycle decisions should also use the ordering code rather than assuming that every XMC4100 package variant is electrically or pin compatible.

Typical Applications
XMC4100F64K128BAXQMA1 is suitable for 6 applications: Industrial Motor Control, Digital Audio Interface, LED Control and Lighting Systems, Industrial Communication Gateway, Distributed Automation Node, Embedded Instrumentation and Control.
Industrial Motor Control
The XMC4100F64K128BAXQMA1 fits industrial motor-control systems that require deterministic pulse generation and efficient data movement. Its 80 MHz ARM Cortex-M4 core can execute speed, position, or current-control algorithms, while the integrated PWM generation supports actuator drive signals and DMA can transfer sampled or buffered data with limited processor intervention. The 128 KB flash provides room for control code and parameter tables, and 20 KB SRAM can hold command structures and real-time working state. Before finalizing the design, engineers must verify the required timer channels, analog inputs, feedback interfaces, and package assignments against the manufacturer datasheet. The watchdog is especially valuable because it can recover the controller after a software or communication fault, while the integrated power-on reset supports defined startup behavior.
Recommended
Digital Audio Interface
The XMC4100F64K128BAXQMA1 is appropriate for embedded digital-audio products requiring a dedicated synchronous serial interface and moderate real-time processing capacity. The integrated I2S peripheral provides a direct path for transmitting or receiving framed audio data, and the 80 MHz processor core can handle protocol control, buffer management, and user-interface tasks. DMA can transfer audio blocks while the CPU performs other processing, reducing the risk of missed service intervals. Its 128 KB flash and 20 KB SRAM are useful for compact firmware, sample buffers, and configuration data. Audio-system qualification should verify the exact I2S instance, supported data widths, clock-source arrangement, DMA channel mapping, and pin multiplexing in the 64-pin package before schematic approval.
Recommended
LED Control and Lighting Systems
The XMC4100F64K128BAXQMA1 can serve as the central controller in multi-channel LED lighting and illumination systems. Its integrated LED-control peripheral is intended to simplify common animation and dimming functions, while the 80 MHz Cortex-M4 core can coordinate lighting sequences, user commands, and diagnostic information. The 128 KB flash supports firmware updates and lighting tables, and the 20 KB SRAM is suitable for frame data and communication buffers. PWM generation provides another possible mechanism for dimming or controlled drive behavior where the exact timer configuration supports the load. Before selecting it for a lighting platform, verify LED-channel counts, output polarity, timing resolution, fault handling, and package pin availability in the manufacturer documentation.
Recommended
Industrial Communication Gateway
The XMC4100F64K128BAXQMA1 is suitable for compact industrial communication nodes that must combine protocol handling with deterministic control tasks. Its 80 MHz ARM Cortex-M4 core provides sufficient instruction throughput for serial framing, state management, and supervisory logic, while DMA can accelerate transfers between memory and communication peripherals. The 128 KB flash accommodates protocol stacks, configuration data, and upgrade routines, and 20 KB SRAM supports packet buffers and connection state. The watchdog improves recovery from software stalls or corrupted task execution, while the power-on reset supports controlled initialization. The verified excerpts do not specify the available serial-channel counts, Ethernet capability, or protocol accelerators, so engineers must confirm that the required interfaces are present before selecting this MCU for a gateway design.
Recommended
Distributed Automation Node
The XMC4100F64K128BAXQMA1 is a practical fit for distributed automation nodes where local sensing, actuator control, and serial connectivity must be consolidated in one package. Infineon identifies the XMC4100-F64K128 BA as an industrial microcontroller, and its 80 MHz Cortex-M4 core can execute local control logic while the 20 KB SRAM holds active process data. PWM generation supports repetitive actuator timing, DMA reduces the burden of moving sensor or control data, and the watchdog improves resilience in unattended equipment. The 128 KB flash is sufficient for a moderate embedded application and field-maintenance routines. Because the verified data does not enumerate GPIO count, ADC channels, or communication peripherals, the complete XMC4100 datasheet should be checked against the node’s I/O and sensing requirements.
Recommended
Embedded Instrumentation and Control
The XMC4100F64K128BAXQMA1 can support embedded measurement and control instruments that require real-time sampling control, local computation, and flexible digital connectivity. The 80 MHz ARM Cortex-M4 core provides a responsive control platform, while DMA assists with transferring sample blocks without blocking other tasks. Its 128 KB flash and 20 KB SRAM accommodate instrument firmware, calibration tables, working variables, and communication buffers. The integrated watchdog helps maintain unattended operation, and PWM generation may be useful for excitation or low-rate stimulus signals. Exact analog performance, timer resolution, and external-interface availability are not disclosed in the supplied excerpts, so designers must verify ADC specifications, trigger behavior, calibration support, and I/O mapping in the official XMC4100/XMC4200 datasheet.

Design Notes
Use the exact PG-LQFP-64-19 pin table from the official XMC4100/XMC4200 datasheet before assigning signals. In particular, verify supply pins, ground pins, analog inputs, timer channels, I2S data and clock lines, DMA requests, and debug functions because the supplied search excerpts do not provide a complete numbered pinout. Preserve the manufacturer’s exposed-pad and copper recommendations, place decoupling capacitors close to the relevant supply pins, and keep high-current return paths away from sensitive analog and communication routes.
Do not treat every Cortex-M4 MCU as a software-compatible substitute for the XMC4100F64K128BAXQMA1. Although XMC4104F64K128ABXQSA1 matches the verified 80 MHz and 128 KB flash headline values and uses the same 64-pin LQFP class, its ADC resources can alter pin allocation, interrupt priorities, timing, and board requirements. Review the official peripheral tables, startup code, linker configuration, register definitions, and errata before replacing the target. The XMC4100F64K128ABXQSA1 is electrically the same base device but changes reel-oriented ordering rather than adding a functional upgrade.
The verified distributor listing identifies a 3.3 V supply, but the supplied excerpts do not contain the complete operating-voltage range, current limits, or regulator requirements. Use the manufacturer’s electrical-characteristics table to select the system rail and external power source, and apply the documented decoupling network without extrapolating limits from another XMC4000 member. Validate startup, brownout, reset release, and maximum operating temperature for the intended industrial environment. Production programming should also use the manufacturer-supported configuration and security procedure.
For motor-control and LED applications, treat the MCU supply as a precision rail even though the XMC4100F64K128BAXQMA1 includes digital control functions. Keep switching-converter output, PWM drive paths, and high-current loads separated from analog and communication routing, and use grounding that minimizes return-current coupling into sensitive nodes. Configure unused pins and inputs according to the manufacturer recommendations, and verify the PWM edge rates, rise times, and impedance of external drivers so that the MCU pin limits are not exceeded.
Compliance Information
The verified excerpts identify the device as an industrial microcontroller but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Consult the current Infineon product page and material-compliance documentation before procurement.
