部品番号: STM32F302K8U6 ✓ 生産中STM32F302K8U6 概要
A microcontroller is a programmable semiconductor device that integrates a processor core, memory, and peripherals into one package. The STM32F3 family uses the Arm Cortex-M4 processor architecture, a 32-bit RISC core designed for embedded control. The STM32F302K8U6 combines this processing capability with mixed-signal resources and communication peripherals, positioning it between simple fixed-function controllers and more highly integrated system-on-chip devices.
The STM32F302x6/8 family operates at up to 72 MHz and includes a floating-point unit for software development involving fractional arithmetic. Its 64 KB Flash configuration supports compact embedded applications, while the 32-pin package reduces board area compared with larger leaded or high-pin-count packages. The device is identified as part of the STM32F302x6/x8 family and is commonly used for industrial control, consumer electronics, and medical-device applications.
The mixed-signal capability makes the MCU useful where a controller must acquire analog measurements and perform control functions in the same compact design. Communication peripherals can connect the device to sensors, actuators, human-interface modules, and external controllers. The Cortex-M4 core also provides a familiar software ecosystem for motor control, signal processing, instrumentation, and general-purpose embedded products.
When designing around the STM32F302K8U6, confirm the exact peripheral assignments, alternate-function mapping, clock tree, and package dimensions against the manufacturer datasheet before routing the PCB. Keep decoupling close to the power pins, provide a stable reference and clock arrangement, and reserve programming and debug access for production programming and field service.
This page combines manufacturer-family specifications, package information, comparison considerations, and practical design guidance for engineers evaluating the STM32F302K8U6 in industrial, medical, consumer, and communications-oriented embedded systems.

主な用途
STM32F302K8U6 の用途: 6 件s: Industrial Motor and Equipment Control, Medical Monitoring and Control, Consumer Sensor and Interface Hub, Precision Instrumentation, Communications and Embedded Gateway, LED Lighting and Display Control.
Industrial Motor and Equipment Control
The STM32F302K8U6 fits compact motor and equipment controllers that require deterministic embedded control in a small footprint. Its Arm Cortex-M4 core runs at up to 72 MHz, providing processing headroom for control loops, state management, and communication tasks, while the integrated FPU supports fractional calculations used in speed, position, and current control. The 64 KB Flash capacity can hold application firmware, parameter tables, and calibration data. The 12-bit ADC and DAC resources also help with analog monitoring and signal conditioning. Designers should review timer-channel assignments, encoder interfaces, analog pins, and the UFQFPN land pattern in the manufacturer documentation before committing the PCB.
おすすめ
Medical Monitoring and Control
The STM32F302K8U6 is suitable for compact medical monitoring and control electronics where a 32-bit processor, analog conversion, and limited board area are important. Its Cortex-M4 core operates up to 72 MHz and includes a floating-point unit for filtering and calibration mathematics, while 64 KB Flash supports embedded firmware and configuration data. The listed 12-bit ADC and DAC capabilities provide a foundation for sensor acquisition, stimulus generation, and signal control functions. Medical deployments still require system-level verification of signal accuracy, isolation, EMC behavior, reliability, and applicable regulatory requirements. Review the exact analog characteristics and operating limits in the current manufacturer documentation.
おすすめ
Consumer Sensor and Interface Hub
The STM32F302K8U6 can serve as the central controller in a compact consumer sensor, interface, or accessory design. Its 72 MHz Cortex-M4 core handles protocol servicing, user interactions, and real-time control, while the integrated FPU accelerates filtering and scaling operations. The 64 KB Flash provides space for application code and product configuration, and the mixed-signal resources support sensing or signal-conditioning tasks. Its 5 x 5 mm UFQFPN package helps preserve board area in wearables, home appliances, and compact peripherals. Firmware designers should account for boot, debug, clock, and reset requirements and confirm peripheral availability on the package balls used by the design.
おすすめ
Precision Instrumentation
The STM32F302K8U6 is appropriate for compact instrumentation that combines digital processing with analog measurement or output. Its 12-bit ADC supports sensor-interface designs, the 12-bit DAC supports controlled analog generation, and the 72 MHz Cortex-M4 processor can execute filtering, calibration, and communications concurrently. The integrated FPU is beneficial for digital signal-processing and control algorithms, while 64 KB Flash provides a practical balance for embedded firmware. Analog accuracy depends on the power supply, reference implementation, analog layout, and calibration strategy, so designers should use the manufacturer electrical characteristics and reference guidance. Keep sensitive analog routing away from fast digital clocks and switching nodes.
おすすめ
Communications and Embedded Gateway
The STM32F302K8U6 can support compact communications nodes that require real-time protocol handling alongside local control. The 72 MHz Arm Cortex-M4 core provides sufficient instruction throughput for serial communications, data formatting, supervision, and control functions, while the integrated floating-point unit assists with signal calculations. The 64 KB Flash capacity is appropriate for gateway firmware that remains primarily supervisory rather than storage-intensive. Available communication peripherals, pin multiplexing, and electrical limits must be checked against the selected interfaces and connector requirements. Because the 32-pin package has limited ball count, prioritize the required communication, debug, clock, and power pins during schematic allocation and validate the final footprint against the package drawing.
おすすめ
LED Lighting and Display Control
The STM32F302K8U6 can serve in LED lighting, display, or illumination-control products that require compact real-time processing and mixed-signal resources. Its Cortex-M4 core at up to 72 MHz can manage timing, dimming logic, fault detection, user commands, and communications, while the FPU supports filtering and compensation calculations. The 12-bit DAC may be useful where an analog control or reference path is required, and 64 KB Flash can hold control firmware, lighting tables, and configuration data. The UFQFPN-32 package helps reduce board area compared with larger MCU packages. Confirm timer outputs, PWM channels, DMA assignments, and pin multiplexing for the intended architecture, and account for thermal conditions that affect LED drivers and power-conversion stages.

設計ノート
Treat the UFQFPN-32 land pattern and exposed thermal pad as a single high-density routing problem. Follow the manufacturer package drawing and recommended footprint, place input and bulk decoupling capacitors close to their designated supply balls, and provide a low-impedance ground path. Because the package has 32 balls, prioritize power, clock, reset, boot, debug, and required communication pins during schematic allocation. Validate the stencil, paste volume, pad definition, and assembly process during PCB bring-up.
Design the supply network so the STM32F302K8U6 receives a stable voltage with low transient impedance. Confirm the device's supported supply range and absolute maximum ratings in the manufacturer documentation before adding external components. Separate sensitive analog routing from digital return currents, connect analog and digital grounds according to the recommended system strategy, and test startup and load-transient behavior across every power mode required by the product.
Assign clock, reset, debug, and communication functions from the exact package pin table rather than from a generic STM32F3 diagram. Some signals have multiple alternate functions, and using the wrong mapping can cause boot, debug, or peripheral conflicts. Keep the 72 MHz clock path short, maintain continuous return paths beneath high-speed traces, and avoid routing switching-node or high-current power traces adjacent to analog inputs. Validate timing and signal integrity with oscilloscope measurements on production-representative hardware.
