STM32F301K6U6 - 72MHz Cortex-M4 MCU | STMicroelectronics
MPN： STM32F301K6U6 ✓ 啟用中STM32F301K6U6 概覽
A microcontroller is a programmable integrated circuit containing a processor core, memory, and peripherals on one device. The STM32F3 family hierarchy places this part within Arm Cortex-M microcontrollers, mixed-signal microcontrollers, and general-purpose embedded processors. Its combination of a Cortex-M4 core, fast Flash execution, SRAM, and mixed-signal peripherals supports compact control systems requiring deterministic real-time performance and efficient peripheral integration.
The STM32F301K6U6 provides 32 KB of Flash for firmware and 16 KB of SRAM for working data. Its Cortex-M4 core includes an FPU and DSP instruction capability, while the operating frequency reaches 72 MHz. The 32-UFQFPN 5x5 mm package supports compact PCB layouts, and the family also includes a CRC calculation unit and reset and power management functions.
STMicroelectronics positions the STM32F301x6/8 family as a high-performance Cortex-M4 platform for mixed-signal applications. The 72 MHz core can execute control logic and DSP operations without requiring a separate digital signal processor. The FPU also allows software to use floating-point arithmetic where the application benefits from it, although final throughput depends on the instruction mix and firmware implementation.
Typical uses include industrial monitoring, digital control, connected sensing, motor and power-system control, communication equipment, and compact consumer products. The STM32F301K6U6 is particularly appropriate when a design needs a small Cortex-M4 device with on-chip Flash and SRAM, deterministic real-time control, and a compact surface-mount footprint.
Designers should verify the exact peripheral assignments, power-supply limits, pin multiplexing, and package details in the manufacturer datasheet before layout is finalized. Because the available verified sources expose only limited device-specific electrical data, voltage ranges, timing limits, peripheral counts, and absolute maximum ratings should not be inferred from the family description. Prototype firmware and hardware should also be validated against the selected MCU and its intended operating environment.

典型應用
STM32F301K6U6 適用於 6 應用s: Industrial Monitoring and Control, Digital Signal Processing, Motor and Power-System Control, Connected Sensor Hubs, Consumer and HMI Devices, Communication Equipment.
Industrial Monitoring and Control
The STM32F301K6U6 fits compact industrial monitoring equipment that must combine real-time control, sensor conditioning, and communications within a constrained board area. Its 72 MHz Arm Cortex-M4 core provides deterministic processing for sensor sampling and control loops, while the hardware FPU and DSP instructions support arithmetic-heavy measurement routines. The 32 KB Flash configuration is suitable for compact firmware, and 16 KB of SRAM provides working memory for control variables and communication buffers. Using the 5x5 mm 32-UFQFPN package also preserves PCB space around connectors and analog circuitry. Verify the exact peripheral assignments, operating voltage, temperature grade, and isolation requirements before industrial deployment.
推薦
Digital Signal Processing
The STM32F301K6U6 is appropriate for embedded DSP functions because its Arm Cortex-M4 core operates up to 72 MHz and includes both a hardware floating-point unit and DSP instructions. These resources can accelerate filtering, waveform analysis, control calculations, and digital compensation without requiring a separate DSP in moderate-performance systems. Its 16 KB of SRAM can support compact working sets, while the 32 KB of Flash provides room for code, constants, and calibration tables. Engineers should benchmark the intended instruction mix because real performance depends on filter structure, memory access, compiler behavior, and data width. Confirm signal-processing peripheral assignments and maximum clock configuration in the manufacturer documentation before finalizing the design.
推薦
Motor and Power-System Control
The STM32F301K6U6 can serve as the central controller in compact motor-control or power-management subsystems where deterministic 32-bit computation, DSP support, and mixed-signal integration are valuable. Its 72 MHz Cortex-M4 core can execute control loops and supervisory logic, and the FPU assists with proportional, integral, derivative, and filtering calculations. The compact 32-UFQFPN 5x5 mm footprint is useful where switching stages, magnetics, and power semiconductors consume most of the PCB area. The exact PWM channels, timer resources, ADC, DAC, and pin multiplexing must be confirmed for the selected board because the verified excerpts do not enumerate them. Thermal design and safe control behavior must be validated at the system level rather than inferred from the MCU frequency.
推薦
Connected Sensor Hubs
The STM32F301K6U6 supports compact connected-sensor designs that combine acquisition, local filtering, and a communication protocol. The 72 MHz Cortex-M4 core can service interrupts and perform sensor conditioning in parallel with network handling, while 16 KB of SRAM accommodates packet buffers and working variables. Its 32 KB Flash is adequate for many compact protocol stacks and application firmware, although code-heavy stacks may require careful optimization or a larger-memory MCU. The 5x5 mm UFQFPN package supports placement near sensors and radio or network components, reducing board congestion. Before layout, verify the selected communications peripherals, oscillator requirements, pin conflicts, and RF coexistence conditions. Firmware must be tested with the actual external transceivers because peripheral availability alone does not guarantee protocol performance.
推薦
Consumer and HMI Devices
The STM32F301K6U6 is suitable for compact human-interface and consumer devices that need responsive 32-bit control without a high-end application processor. The Cortex-M4 core at up to 72 MHz can manage buttons, displays, indicators, and local user logic, while the DSP instructions and FPU improve responsiveness for animation, filtering, or audio-oriented processing. Its 32 KB Flash and 16 KB SRAM are intended for embedded UI firmware rather than rich operating systems. The small 32-UFQFPN package helps reduce PCB size in wearables, appliance controllers, and compact instrument panels. Display interface pins, operating voltage, ESD requirements, and available I/O count must be verified from the exact datasheet. Mechanical and environmental requirements should be assessed separately from the MCU's electrical capabilities.
推薦
Communication Equipment
The STM32F301K6U6 can be used in compact communication equipment as a supervisory or protocol-processing controller. At up to 72 MHz, the Cortex-M4 core provides sufficient throughput for packet handling, framing, state machines, and supervisory tasks, while its DSP instructions can support signal conditioning around data converters. The 16 KB SRAM is useful for short frame buffers and protocol state, and the 32 KB Flash can hold compact firmware for a dedicated function. The 5x5 mm UFQFPN package leaves board area for external transceivers, clocks, and power management. The verified excerpts do not identify the exact serial-interface allocation, so designers must confirm UART, SPI, I2C, USB, or other interface availability and pin assignments. Conduct timing and interoperability testing with the selected PHY or transceiver.

設計說明
Do not treat a shared 32-UFQFPN footprint as proof of unconditional interchangeability. For every proposed alternative, compare the complete manufacturer pin table, exposed-pad connection, supply pins, ground pins, debug pins, oscillator pins, and peripheral assignments. The target's supplied data establishes the 32-pin 5x5 mm package but does not provide a complete verified pin map. Freeze the PCB only after checking the exact schematic and package drawing, and avoid assuming that bootloader behavior or firmware image compatibility follows automatically from family membership.
Route the exposed thermal pad according to the manufacturer land pattern and assembly process rather than copying a generic QFN footprint. Thermal-pad connection, solder mask definition, paste volume, and copper treatment can affect assembly yield and heat dissipation. Place required decoupling components close to the device's verified power pins, keep sensitive analog and communication routes away from fast switching nodes, and follow the datasheet's guidance for oscillator and high-current paths. Because verified pin assignments and voltage limits were not supplied, consult the exact STM32F301K6 package drawing before releasing fabrication files.
Validate the complete power tree across voltage tolerance, startup, idle, active, and maximum CPU-frequency conditions before applying the 72 MHz operating point. The verified excerpts do not provide the target's supply-voltage range or current consumption, so those values must not be inferred from related devices. Check the regulator headroom, transient response, decoupling network, and brownout behavior, and measure startup current if the product uses a battery. Any power calculation should use the manufacturer limits and operating conditions applicable to the exact STM32F301K6U6 grade.
合規資訊
The supplied verified results do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not_applicable because this is a general-purpose microcontroller and no automotive qualification was identified in the supplied data.
