STM32G081GBU6 - 64MHz Cortex-M0+ 128KB MCU | STMicroelectronics
部品番号: STM32G081GBU6 ✓ 生産中STM32G081GBU6 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and interfaces into one device. STM32G0 devices belong to the ARM Cortex-M0+ embedded-control family and provide a compact platform for industrial controls, consumer products, sensor systems, communications equipment, and connected devices. The STM32G081GBU6 combines a small package with broad peripheral support for space-constrained designs.
Key features include the 64 MHz Cortex-M0+ core, 128 KB of Flash, 36 KB of RAM, and a 28-pin UFQFPN package measuring 4 x 4 mm. The STM32G081xB family is positioned for general-purpose embedded applications where low power, compactness, and a broad set of communication and timing peripherals are useful. STMicroelectronics identifies the device as a mainstream Arm Cortex-M0+ MCU.
The Cortex-M0+ architecture supports efficient real-time control while keeping software development straightforward. Flash memory provides room for application code, boot routines, configuration data, and firmware updates, while RAM supports working state, buffers, stacks, and peripheral data handling. The compact 4 x 4 mm package makes the device suitable for designs where connector density and PCB area are important constraints.
Typical applications include low-cost consumer controllers, industrial sensing nodes, compact motor-control modules, building and access peripherals, communication equipment, and low-power embedded products. The device can be used where a small MCU package, deterministic control, and flexible serial connectivity are needed without the footprint of a larger microcontroller.
Designers should review the STM32G081GBU6 datasheet for the exact pin assignments, peripheral multiplexing, electrical limits, decoupling requirements, clock configuration, programming interface, and exposed-pad layout before finalizing a PCB. The UFQFPN package also requires careful land-pattern design and thermal management because its small dimensions can limit heat dissipation.
This product summary combines the manufacturer product information, distributor listings, package details, memory specifications, and the STM32G081 family positioning. It is intended to help engineers identify the correct device, compare it with potential replacements, plan applications, and move directly to the authoritative datasheet for design decisions.

主な用途
STM32G081GBU6 の用途: 6 件s: Compact Industrial Sensor Node, Low-Voltage Motor Actuator, Consumer Device Controller, Building and Access Peripheral, Connected Equipment Controller, Small Signal Conditioning Module.
Compact Industrial Sensor Node
The STM32G081GBU6 fits compact sensor nodes that must process local measurements and communicate through embedded peripherals while occupying little PCB area. Its 64 MHz Cortex-M0+ core supports responsive control and filtering, while 128 KB of Flash accommodates application firmware, calibration data, and protocol handling. The 36 KB RAM is suitable for working buffers and moderate data acquisition tasks. Its 28-pin UFQFPN 4 x 4 mm footprint also leaves board space for sensors, power conversion, and connectors. Before selecting it, verify the required ADC channels, serial interfaces, supply limits, low-power modes, and exposed-pad thermal requirements in the manufacturer datasheet.
おすすめ
Low-Voltage Motor Actuator
The STM32G081GBU6 can serve as the control MCU in a compact actuator or low-voltage motor-control module. A 64 MHz Cortex-M0+ core provides enough performance for deterministic control loops, while 128 KB of Flash and 36 KB of RAM support motion-state logic and communication tasks. The 4 x 4 mm UFQFPN package is valuable in compact motor-drive assemblies. The final design must confirm the available timer channels, PWM outputs, ADC inputs, operating voltage, and thermal limits for the selected motor and driver topology.
おすすめ
Consumer Device Controller
The STM32G081GBU6 is appropriate for compact consumer products that need programmable control without a large mixed-signal package. Its 64 MHz Cortex-M0+ core can manage buttons, indicators, relays, and local communication logic, while 128 KB of Flash provides room for user-interface and configuration firmware. The small 28-pin UFQFPN package helps reduce the controller footprint inside wearables, household accessories, and personal equipment. Check the available peripheral mix and pin multiplexing against the product requirements before assigning board functions.
おすすめ
Building and Access Peripheral
The STM32G081GBU6 can be used in compact access-control, keypad, door-interlock, or building-peripheral modules where local logic and serial communications are required. The Cortex-M0+ processor handles device-state management, and the 128 KB Flash supports firmware for authentication, logging, and configuration. The 4 x 4 mm package helps reduce enclosure size, while 36 KB RAM supports message buffers and protocol state. Confirm the required communication interfaces, security peripherals, supply range, and temperature grade against the STM32G081 documentation.
おすすめ
Connected Equipment Controller
The STM32G081GBU6 provides a compact control platform for connected equipment that links local machine functions to a serial communications module. Its 64 MHz core can manage protocol tasks and real-time control, while 128 KB Flash and 36 KB RAM are adequate for embedded firmware and communication buffers. The UFQFPN 4 x 4 mm package minimizes PCB space in gateways, controllers, and instrumentation. The designer should verify the exact USART, SPI, or I2C resources, pin assignments, clock tree, and low-power requirements before finalizing the communication architecture.
おすすめ
Small Signal Conditioning Module
The STM32G081GBU6 is suitable for compact signal-conditioning and measurement modules that require local control, calibration, and data handling. Its 64 MHz Cortex-M0+ core can execute digital filtering and calibration routines, while 128 KB Flash stores application code and 36 KB RAM accommodates buffers. The small 28-pin UFQFPN package supports high-density analog and interface layouts. Engineering review must establish ADC resolution, sampling capability, reference requirements, input bandwidth, operating voltage, and calibration strategy from the manufacturer documentation.

主な差別化要因
- Compact 4 x 4 mm footprint with substantial embedded resources （vs Larger STM32G0 devices in higher-pin-count packages)
- Mainstream Arm Cortex-M0+ positioning （vs Cross-brand Cortex-M MCUs without verified pin compatibility)
- Memory capacity suited to embedded control tasks （vs Entry-level Cortex-M0+ MCUs with 64 KB or less Flash)
設計ノート
Use the manufacturer land pattern for the 28-pin UFQFPN 4 x 4 mm package and preserve the exposed-pad geometry and paste recommendations. The exact pad dimensions are not present in the product listing, so do not scale a generic QFN footprint. Validate the stencil, assembly profile, and reflow profile against the STMicroelectronics package drawing before releasing the PCB.
Confirm the device supply range, internal regulator behavior, power-consumption limits, and decoupling requirements from the STM32G081 datasheet. Place required input, output, and VDDCORE capacitors adjacent to their associated pins, with the shortest possible ground return. Configure unused pins according to the manufacturer guidance rather than leaving their electrical state to board-level assumptions.
The UFQFPN package is only 4 x 4 mm, so thermal performance depends heavily on the exposed pad, copper area, and board construction. Use the datasheet thermal model to estimate junction temperature for the actual CPU load and ambient temperature. Where operating loss is significant, extend copper into a thermal-via field and avoid placing heat-generating components directly beneath the MCU.
Do not assume that another STM32G0 or Cortex-M0+ MCU is a drop-in replacement merely because it has a similar package. Pin multiplexing, memory capacity, timers, ADC channels, clock limits, bootloader behavior, and peripheral instances can differ. Approve a substitute only after comparing the complete ordering code and every connected net against both datasheets.
