STM32G071CBU6 Descripción general
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. In the product hierarchy, the STM32G071CBU6 is a microcontroller, or MCU, built around the Arm Cortex-M0+ CPU core within the STM32G0 embedded-processing family. Its compact package and broad peripheral set make it suitable for small control boards, consumer accessories, and industrial equipment where space, cost, and deterministic real-time performance matter.
Key features include a maximum 64 MHz operating frequency, 128 KB of Flash for firmware, and 36 KB of SRAM for working data. The verified distributor listing identifies four USART peripherals and the family documentation confirms 64 MHz operation. The part also integrates an ADC, DAC, timers, and communication interfaces, enabling a compact design without requiring separate external converters or interface devices.
Its Cortex-M0+ architecture provides a straightforward 32-bit instruction set and efficient real-time control. The STM32G0 family is intended for mainstream embedded applications, where engineers value low system complexity alongside useful analog conversion and serial communications. At 64 MHz, the processor can execute control loops and manage multiple peripherals while retaining deterministic timing for motor, sensing, and communications tasks.
Typical uses include compact motor-control modules, digital sensor controllers, connected home accessories, USB Type-C peripheral equipment, and general-purpose industrial control nodes. The 48-UFQFPN 7 x 7 mm package helps reduce PCB area, although its fine pitch requires careful assembly, land-pattern verification, and thermal-via planning.
When designing around the STM32G071CBU6, verify every board-level pin assignment against the current STMicroelectronics datasheet and package drawing. Place decoupling capacitors close to supply pins, keep sensitive analog paths away from fast digital switching, and confirm firmware, bootloader, and peripheral requirements before committing to this exact orderable variant.
This page consolidates verified manufacturer and distributor information, package constraints, practical design guidance, and candidate drop-in alternatives. It also identifies parameters that require datasheet confirmation, helping engineers distinguish confirmed STM32G071CBU6 facts from assumptions before PCB release or production sourcing.

Aplicaciones típicas
STM32G071CBU6 es adecuado para 6 aplicacións: Compact Motor-Control Modules, Digital Sensor Hubs, USB Type-C Accessories, Connected Home Accessories, Programmable Logic and Timing, General-Purpose Control Boards.
Compact Motor-Control Modules
The STM32G071CBU6 fits compact motor-control modules that need deterministic control processing without a large mixed-signal controller. Its Arm Cortex-M0+ core operates up to 64 MHz, while the 128 KB Flash and 36 KB RAM provide room for control algorithms and communication stacks. Four USARTs and integrated timers simplify connection to a driver, encoder, diagnostics tool, or host processor. The 48-UFQFPN 7 x 7 mm package limits board area, while its fine pitch requires a qualified PCB assembly process. According to the verified manufacturer page, the device is a mainstream STM32G0 Cortex-M0+ MCU designed around an efficient embedded-control architecture.
Recomendado
Digital Sensor Hubs
The STM32G071CBU6 is appropriate for digital sensor hubs that combine analog measurement, conditioning, and serial reporting. Its integrated ADC and DAC support acquisition and stimulus or reference functions, while four USARTs can serve sensors, a local display, or an upstream controller. At up to 64 MHz, the Cortex-M0+ core can supervise multiple acquisition channels and filtering tasks alongside its 128 KB Flash and 36 KB RAM. The compact UFQFPN package helps reduce board footprint, although analog traces should remain separated from digital clocks and switching outputs according to the manufacturer layout guidance.
Recomendado
USB Type-C Accessories
The STM32G071CBU6 can serve as the controller in compact USB Type-C accessories when the exact package variant confirms the required interface and pin availability. Its 64 MHz Cortex-M0+ core, 128 KB Flash, and 36 KB RAM are sufficient for protocol handling, configuration, diagnostics, and human-interface functions, while the four USARTs support debugging and peripheral expansion. Compared with a larger host MCU, the 7 x 7 mm UFQFPN preserves board area. Designers should still verify USB data pins, VBUS handling, connector protection, and firmware support directly in the STMicroelectronics datasheet before schematic release.
Recomendado
Connected Home Accessories
The STM32G071CBU6 supports small connected-home accessories that combine local control with a serial communications module. Four USARTs allow concurrent sensor polling, module communication, diagnostics, and factory programming, while the 64 MHz Cortex-M0+ core handles protocol tasks and real-time control. The 128 KB Flash and 36 KB RAM support a compact firmware image without forcing an external memory device, and the 7 x 7 mm package fits densely populated accessory boards. For radio-connected products, preserve antenna clearance, isolate switching supplies, and verify regulatory and low-power requirements separately from the MCU datasheet.
Recomendado
Programmable Logic and Timing
The STM32G071CBU6 is useful for small programmable logic, sequencing, and timing modules because the 64 MHz Cortex-M0+ core can implement deterministic state machines and peripheral coordination. Integrated timers support event counting, pulse generation, and motor-control tasks, while four USARTs enable programming and monitoring. Its 128 KB Flash and 36 KB RAM allow meaningful application logic to remain on-chip, reducing board area and cost. The 48-pin UFQFPN provides many signal options in a 7 x 7 mm footprint, but the design must account for exact pin multiplexing, debounce or level-shifting requirements, and startup behavior after power loss.
Recomendado
General-Purpose Control Boards
The STM32G071CBU6 is a practical MCU for general-purpose control boards that need mixed analog and serial I/O without a high-end application processor. Four USARTs, integrated ADC and DAC resources, timers, 128 KB Flash, and 36 KB RAM cover common control, monitoring, and configuration tasks. Its 64 MHz Cortex-M0+ core adds useful throughput while remaining broadly supported by embedded tooling. The 48-UFQFPN 7 x 7 mm package can reduce board size, but designers should verify exposed-pad soldering, power sequencing, decoupling, and all peripheral pin multiplexing against the current manufacturer documentation.

Notas de diseño
Use the manufacturer land pattern for the 48-pin UFQFPN 7 x 7 mm package and preserve its exposed-pad and thermal-via requirements. Place every required decoupling capacitor directly beside its associated supply pin and provide a low-impedance ground reference. The 0.5 mm pitch limits solder-bridging margin, so control stencil apertures, solder-mask dams, and paste volume according to the package assembly guidelines.
Separate analog and digital return paths carefully. Route ADC inputs away from clocks, PWM outputs, inductors, and high-current switching nodes; use a quiet ground strategy and short reference paths for analog returns. Because the STM32G071CBU6 integrates both ADC and DAC, review the package pin assignments and analog-supply requirements in the current STMicroelectronics datasheet before fixing the board floorplan.
Do not assume that every STM32G071CB ordering code is automatically interchangeable. Verify the temperature suffix, memory code, package drawing, pin multiplexing, and exposed pad for every substitution, especially STM32G071CBT6, STM32G071CBU6TR, STM32G071C8U3, STM32G0B1CBU6, and STM32G071CBU3. Also confirm supply limits and current consumption from the exact datasheet because they are not present in the supplied source excerpts.
Información de cumplimiento
The supplied verified excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for STM32G071CBU6. These fields remain unknown rather than inferred from the manufacturer or package family.
