部品番号: STM32G031G6U6TR ✓ 生産中STM32G031G6U6TR 概要
A microcontroller is a complete embedded-processing component containing a CPU core, program memory, data memory, peripherals, clocking, debug facilities, and input/output interfaces. The STM32G0 family belongs to the embedded MCU and 32-bit RISC processor hierarchy. Its Cortex-M0+ core provides a compact software ecosystem, while the STM32G031G6U6TR combines 64 MHz processing with 32 KB Flash and 8 KB RAM for control, communication, sensing, and user-interface tasks.
The verified device data identifies an Arm Cortex-M0+ core, 32-bit architecture, 64 MHz maximum frequency, 32 KB Flash, 8 KB SRAM, and a 28-UFQFPN 4 x 4 mm package. Mouser additionally identifies two USART peripherals. STMicroelectronics positions the STM32G031x4/x6/x8 mainstream range for general embedded applications, allowing developers to use a small MCU for compact industrial, consumer, sensor, and communication products.
The UFQFPN package supports dense PCB integration while keeping the footprint within 4 x 4 mm. Because the provided data does not include the complete pin names, electrical limits, timing characteristics, or environmental ratings, those values must be confirmed against the official STMicroelectronics product documentation before schematic capture, PCB release, or production qualification.
Typical design roles include low-cost sensor controllers, compact sensor hubs, small motor-control supervisory circuits, industrial modules, communication equipment, and embedded control panels. The 64 MHz CPU and 32 KB Flash provide useful performance and code space for lightweight protocol handling and control loops, while 8 KB RAM should be checked against the selected application’s stack and buffer requirements.
The principal design check is software and peripheral fit rather than package size alone. Validate the required USART count, pin multiplexing, clock tree, ADC resources, timers, communication peripherals, memory usage, and low-power behavior against the official datasheet. Keep power decoupling close to the device and confirm exposed-pad or thermal-layout requirements from the package drawing before manufacturing.
This product record combines the verified manufacturer and distributor identity, pricing source, core and memory specifications, package information, and application-oriented engineering guidance. It also records unavailable parameters explicitly rather than guessing, helping engineers distinguish verified facts from data that must be completed during design-in.

主な用途
STM32G031G6U6TR の用途: 6 件s: Compact Sensor Controller, Small Motor-Control Supervisor, Industrial Communication Module, Battery-Powered Monitoring Device, Embedded Consumer Appliance Controller, Compact Data Acquisition Front End.
Compact Sensor Controller
The STM32G031G6U6TR fits compact sensor-controller designs because its Arm Cortex-M0+ core operates up to 64 MHz while the device remains in a 4 x 4 mm 28-UFQFPN package. A firmware task can acquire sensor data, apply digital filtering, maintain control thresholds, and expose status through one of the two verified USART peripherals. The 32 KB Flash and 8 KB RAM are adequate for compact embedded applications, but engineers should reserve memory for the stack, buffers, drivers, and protocol code. Confirm ADC, timer, and pin requirements in the official datasheet before committing the design.
おすすめ
Small Motor-Control Supervisor
STM32G031G6U6TR can serve as a supervisory controller in small motor systems where a higher-performance motor driver handles power conversion while the MCU manages commands, interlocks, fault reporting, and timing. The 64 MHz Cortex-M0+ core provides enough instruction throughput for control-state logic, while two USARTs can support a host interface and an external controller. The compact 28-UFQFPN footprint helps reduce board area. Before implementation, verify timer outputs, encoder or sensor inputs, fault pins, voltage levels, and motor-driver timing requirements in the official device documentation.
おすすめ
Industrial Communication Module
The STM32G031G6U6TR is appropriate for small communication modules that need local protocol handling, configuration storage, status LEDs, and host connectivity. Its two USARTs provide a basis for dual serial-channel designs, and the 64 MHz core can service lightweight framing and control tasks. The 32 KB Flash and 8 KB RAM should be checked against the selected protocol stack, logging requirements, and update mechanism. Verify the exact USART pin multiplexing, peripheral clocks, supply range, and any required transceiver level conversion before layout.
おすすめ
Battery-Powered Monitoring Device
STM32G031G6U6TR can support battery-powered monitoring equipment where low board area and a modest processing footprint are important. The controller can periodically wake from a low-power state, read sensors, process thresholds, and report through one of the verified USART channels. The 28-UFQFPN 4 x 4 mm package helps fit the MCU beside sensing and power circuitry. Actual battery life depends on the selected operating mode, clock configuration, analog front end, and firmware duty cycle; these values are not included in the supplied data and must be verified before design completion.
おすすめ
Embedded Consumer Appliance Controller
STM32G031G6U6TR can be used in compact consumer products for local control, user-input handling, status indication, and serial configuration. Its Cortex-M0+ core, 32 KB Flash, and 8 KB RAM are suitable for small control products that do not require a high-end application processor or extensive connectivity. The 4 x 4 mm package reduces PCB area, while two USARTs can assist with configuration or external accessory control. Validate ESD, temperature, EMC, and power-supply requirements for the final product because those application-level specifications are not provided in the verified snippets.
おすすめ
Compact Data Acquisition Front End
STM32G031G6U6TR can act as the control MCU for a small data-acquisition front end that samples sensors, timestamps events, filters readings, and forwards results to a host. The 64 MHz core supports responsive interrupt and control-loop handling, while the 32 KB Flash and 8 KB RAM constrain the chosen buffering and logging strategy. The 28-UFQFPN package permits placement close to the analog circuitry, helping reduce board area and routing complexity. Confirm the ADC architecture, sampling time, trigger inputs, reference voltage, and required calibration workflow in the official datasheet.

設計ノート
Use the official 28-UFQFPN land pattern and keep the device footprint within the manufacturer’s assembly recommendations. Place decoupling capacitors close to the appropriate power pins and route the exposed pad or thermal-related copper exactly as shown in the package drawing. The supplied data confirms the 4 x 4 mm package but does not provide the complete pinout, so do not finalize PCB routing from a generic UFQFPN footprint.
Validate the supply-voltage range, power sequencing, and reset requirements from the official STM32G031G6 documentation before applying the device in a product. The verified snippets identify the CPU and memory resources but do not provide absolute maximum ratings or minimum operating voltage. Use the manufacturer’s recommended decoupling and power-filtering layout, and verify brownout behavior, clock startup, and peripheral current consumption against the final system load.
Plan the two USART connections and all required debug, boot, and clock signals before fixing the PCB layout. Although the package is compact, alternate-function routing can constrain which peripherals can be used simultaneously. Check the official pin table for USART instances, debug interface, clock pins, and exposed-pad requirements. For communication or sensor boards, keep noisy switching and motor-drive return currents away from the MCU ground and analog reference paths.
Do not assume that a related STM32G031 suffix is a drop-in replacement until memory density, package dimensions, pin mapping, peripheral availability, and firmware startup requirements are verified. The supplied cross-reference data identifies comparison candidates but does not prove full compatibility. Also avoid selecting the part solely from its 64 MHz rating: confirm that 32 KB Flash and 8 KB RAM accommodate the bootloader, libraries, stack, RTOS, and application buffers.
Estimate actual power dissipation from the selected operating voltage, clock frequency, active peripherals, and GPIO load rather than relying on a generic MCU power figure. The provided data does not include current consumption or thermal resistance, so no numerical estimate is included here. Use the manufacturer’s maximum ratings and package thermal data, preserve exposed-pad copper where applicable, and test junction temperature in the final enclosure and ambient conditions.
コンプライアンス情報
The supplied verified snippets identify the product and package but do not provide compliance declarations. Compliance status must be confirmed from the current STMicroelectronics product documentation or supplier certificates.
