STM32G071KBU6 Présentation

STMicroelectronics STM32G071KBU6 is a 32-bit Arm Cortex-M0+ microcontroller rated up to 64 MHz, with 128 KB of Flash memory and 36 KB of SRAM, housed in a 32-pin UFQFPN 5x5 mm package with an exposed pad. The device supports 1.8 V, 2.5 V, and 3.3 V operation, making it suitable for compact embedded systems that require substantial memory in a small footprint.

A microcontroller is the central processing element of an embedded control system. It integrates a processor core, program memory, data memory, peripherals, and communication interfaces onto one semiconductor device. In the product hierarchy, the STM32G0 family belongs to the Arm Cortex-M class of 32-bit RISC microcontrollers, combining deterministic embedded control with extensive peripheral integration.

Verified distributor information identifies 128 KB of Flash, 36 KB of RAM, a 64 MHz CPU, and four serial communication interfaces. Its 32-UFQFPN package occupies only 5 x 5 mm and includes an exposed pad for PCB-level thermal dissipation. The STM32G071KBU6 is also offered in tray packaging according to distributor data, which can simplify prototyping and low-to-medium-volume assembly planning.

The Arm Cortex-M0+ architecture uses a compact instruction set optimized for embedded workloads rather than application-computing performance. Its operating frequency supports responsive control, peripheral servicing, and connected-product logic while retaining a straightforward programming model. Exact peripheral assignments, GPIO alternate functions, electrical limits, timers, analog features, and memory details must be confirmed against the manufacturer documentation before schematic capture.

Typical design targets include industrial control modules, compact sensor nodes, building automation equipment, consumer accessories, motor-control peripherals, and low-power connected products. The MCU can serve as the supervisory controller for displays, communications, actuators, and data acquisition when the required interfaces and operating limits match the complete STM32G071KB hardware definition.

A key design consideration is exposed-pad layout. The thermal pad must be connected to the intended copper and ground strategy required by the manufacturer package guidance, while supply decoupling and signal-routing decisions must follow the STM32G0 reference design guidance. Firmware replacement also requires review: a physically compatible MCU is not automatically software-compatible if peripheral mappings or register behavior differ.

This product record consolidates verified distributor inventory data, official family information, package details, sourcing links, and replacement-screening limitations. It distinguishes true pin-compatible drop-in candidates from merely related STM32 devices so procurement and engineering teams can make a safer sourcing decision.

Applications typiques

STM32G071KBU6 convient pour 6 applications: Industrial Control Module, Compact Sensor Node, Building Automation Controller, Motor-Control Peripheral, Consumer Accessory Controller, Connected Data-Acquisition Unit.

🏭

Industrial Control Module

The STM32G071KBU6 fits compact industrial control modules that coordinate sensors, digital I/O, communications, and actuator logic. Its 64 MHz Arm Cortex-M0+ core provides control-loop responsiveness, while 128 KB of Flash and 36 KB of RAM give embedded firmware room for protocol handlers, state machines, diagnostics, and parameter storage. The 32-UFQFPN 5 x 5 mm package reduces board area without requiring a large microcontroller. The four verified serial communication interfaces are useful when connecting local sensors or downstream controllers. Before production use, verify the exact peripheral assignments, operating-temperature grade, isolation strategy, and exposed-pad layout in the full manufacturer documentation.

🧩

Compact Sensor Node

STM32G071KBU6 is a practical candidate for space-constrained sensor nodes that sample inputs, apply local filtering, record diagnostics, and transmit measurements. The Cortex-M0+ core operates up to 64 MHz for responsive protocol servicing, while 36 KB of SRAM can support buffering and real-time processing. A 128 KB Flash budget accommodates firmware, calibration data, and update logic. Its 5 x 5 mm UFQFPN package leaves more board area for sensors and radio or wired connectivity. Designers should confirm ADC characteristics, timer resources, low-power modes, pin multiplexing, and the exact exposed-pad connection before selecting the final schematic and PCB stack-up.

🏠

Building Automation Controller

The STM32G071KBU6 can serve as the local controller in building-automation equipment such as room-control modules, sensor aggregation units, and compact actuator interfaces. Four verified serial communication interfaces support multiple connectivity choices, while the 64 MHz core handles protocol tasks and deterministic control logic. Its 36 KB RAM and 128 KB Flash balance embedded workload capacity against a small 5 x 5 mm package. For deployment, engineers must validate low-power behavior, supply tolerances, ESD requirements, watchdog strategy, and any environmental qualification appropriate to the installation. Firmware should also be structured so communication retries and sensor faults cannot lock up the controller.

⚡

Motor-Control Peripheral

STM32G071KBU6 is suitable as a supervisory MCU in compact motor-control subsystems where it handles command parsing, sensor monitoring, fault logic, and communication with a dedicated power stage. The 64 MHz Cortex-M0+ core can service timing-sensitive control tasks, and the 128 KB Flash provides space for protocols and diagnostics. The MCU should not be assumed to replace a dedicated gate driver or power MOSFET; instead, it coordinates low-voltage control around those components. Verify available timer channels, capture functions, encoder interfaces, analog inputs, and fault-response timing in the full STM32G071KB documentation before assigning safety-related or production motor functions.

📱

Consumer Accessory Controller

The STM32G071KBU6 fits compact consumer accessories that combine local buttons, indicators, sensors, and communications in a small PCB. Its 128 KB Flash and 36 KB RAM support application firmware, protocol stacks, and state management, while the 5 x 5 mm UFQFPN package reduces enclosure footprint. Four serial interfaces create options for external modules or service connections, although the exact alternate-function mapping must be checked for the selected pins. Designers should also budget for ESD protection, accessible recovery or firmware update, exposed-pad assembly, and supply filtering. Those checks are essential because a compact package alone does not guarantee production readiness.

📟

Connected Data-Acquisition Unit

STM32G071KBU6 can coordinate a compact data-acquisition unit when measurements are preprocessed locally and then sent through a communications interface. The 64 MHz core manages control flow, 36 KB of RAM supports short acquisition buffers, and 128 KB of Flash accommodates drivers and communications firmware. Its four serial interfaces provide useful integration options, while the small package leaves room for analog and isolation components. The verified excerpts do not include ADC resolution or sampling rates, so engineers must verify those specifications before setting the acquisition bandwidth. External filtering, reference design, grounding, calibration, and isolation should be designed alongside the MCU rather than added after layout.

What are the key specifications of STM32G071KBU6 that engineers should know?
The STM32G071KBU6 is a 32-bit Arm Cortex-M0+ microcontroller operating up to 64 MHz with 128 KB of Flash, 36 KB of RAM, four serial communication interfaces, and a 32-UFQFPN package measuring 5 x 5 mm. According to the official STMicroelectronics product page and DigiKey listing, it belongs to the STM32G0 mainstream family and supports 1.8 V, 2.5 V, and 3.3 V supply levels. The exposed pad requires deliberate PCB copper and assembly planning.
Where can I download the STM32G071KBU6 datasheet?
The official STM32G071KB documentation is available on the STMicroelectronics product page at https://www.st.com/en/microcontrollers-microprocessors/stm32g071kb.html. Octopart also provides a datasheet entry at https://octopart.com/datasheet/stmicroelectronics/STM32G071KBU6. The official ST page is the preferred starting point because the STM32G071x8/xB family documentation covers ordering information, electrical characteristics, peripherals, package drawings, and firmware considerations.
Where can I find the STM32G071KBU6 pinout?
The STM32G071KBU6 pinout is documented in the manufacturer package information associated with the STM32G071KB family datasheet and product resources. The verified package configuration is 32-UFQFPN in a 5 x 5 mm format with an exposed pad. A complete 32-pin map is not present in the supplied search data, so this record does not invent terminal names or numbering; consult the official STMicroelectronics datasheet before laying out or assembling the PCB.
What is the price of STM32G071KBU6?
The only explicit unit-price value in the supplied verified data is $5.2250 from Heisener, which also reports 50,766 pieces in stock and describes the lead time as requiring confirmation. Pricing is therefore $5.2250 as of 2026-10-22, based on that distributor listing. DigiKey, Mouser, Arrow, Octopart, and WIN SOURCE product pages were found, but their individual prices were not included in the verified excerpts and are therefore not substituted or estimated.
Where can I buy STM32G071KBU6 online?
The verified listings place STM32G071KBU6 at DigiKey, Mouser, Arrow, WIN SOURCE, Heisener, and Octopart. DigiKey describes it as available to buy and ship, while Heisener explicitly reports 50,766 pieces in stock at $5.2250 each as of 2026-10-22. Because distributor inventory can change rapidly, confirm the quantity, packaging, date code, and current lead time at the selected authorized seller before issuing a purchase order.
What is the lead time for STM32G071KBU6?
The STM32G071KBU6 lead time is not uniformly confirmed by the supplied data. Heisener states that the lead time is to be confirmed and shows estimated delivery dates from July 13 through July 18, while other distributor pages indicate purchasing and shipping without supplying a verified numeric lead time. Procurement should request a written quotation and current availability from the chosen distributor rather than relying on the stale estimated delivery window.
Is STM32G071KBU6 in stock?
STM32G071KBU6 is reported in stock by Heisener, which lists 50,766 pieces, and DigiKey states that the part can be purchased and shipped. These statements are distributor-specific and were verified on 2026-10-22. Manufacturer lifecycle status is presented as active based on the current product resources, but actual stock should still be checked at checkout because allocation, package quantity, and regional inventory can change.
What is the difference between STM32G071KBU6 and STM32G071KBU3?
The available comparison data identifies STM32G071KBU3 as a related alternative with STM32G071KBU6, but it does not provide enough verified electrical detail to establish unqualified drop-in compatibility. The ordering suffix can indicate differences such as temperature range, qualification, or supported operating conditions, while U3 and U6 also appear in distinct ordering contexts. According to the manufacturer family documentation is required before substitution because electrical limits, qualification, and lifecycle commitments must match.
Can STM32G071K8U6 replace STM32G071KBU6?
STM32G071K8U6 is identified by a distributor comparison page as a closely related STM32G071 device, but the supplied data does not confirm identical memory, qualification, temperature range, or ordering compatibility. Because both parts may use the same general family or package terminology, physical fit alone is insufficient. Use the official STM32G071KB and STM32G071K8 ordering information to verify the exact flash configuration, temperature grade, product status, and package dimensions before treating it as a drop-in replacement.
When should I choose STM32G071KBU6 instead of another STM32 microcontroller?
Choose STM32G071KBU6 when the design specifically benefits from 64 MHz Cortex-M0+ performance, 128 KB of Flash, 36 KB of RAM, and a compact 5 x 5 mm UFQFPN footprint. The verified data also identifies four serial communication interfaces and operation at 1.8 V, 2.5 V, or 3.3 V. Select another STM32 only after its memory, peripherals, package, qualification, and firmware requirements have been compared rather than choosing solely by processor family.
Is STM32G071KBU6 suitable for industrial control and sensor-node applications?
The STM32G071KBU6 is technically suitable as a candidate for compact industrial controllers and sensor nodes because it combines a 64 MHz Cortex-M0+ core, 128 KB of Flash, 36 KB of RAM, and four serial communication interfaces in a 5 x 5 mm package. Suitability is conditional: verify operating temperature, analog and timer specifications, ESD requirements, watchdog behavior, and long-term supply commitments in the full manufacturer documentation before production release.
What can replace STM32G071KBU6?
No replacement should be approved from the supplied evidence alone. Related STM32G071 order codes appear in the cross-reference results, but the verified excerpts do not establish the required same-package pin map, electrical equivalence, firmware compatibility, qualification, and lifecycle status for five drop-in options. A genuine replacement requires an identical 32-UFQFPN land pattern, matching exposed-pad requirements, compatible supply and I/O limits, equivalent peripheral mappings, and acceptable firmware migration effort.
Is there a cross-brand drop-in equivalent for STM32G071KBU6?
No verified cross-brand drop-in equivalent is available in the supplied alternatives data. The cross-reference results are general search tools, STM32 comparisons, or related-device pages rather than a manufacturer-confirmed pin-to-pin cross-brand substitution. A competitor MCU should not be called drop-in solely because it is an Arm Cortex-M0+ device; boot, peripheral, interrupt, timing, ADC, communications, and software-driver differences can make an otherwise similar MCU non-equivalent.
STM32G071KBU6 vs STM32G071CBT6TR: which one fits my design?
The supplied comparison data associates both devices with the STM32G071 family and reports a supply range of 1.7 V to 3.6 V, but it does not establish identical package dimensions or complete pin compatibility. STM32G071KBU6 is verified as 32-UFQFPN with 128 KB of Flash and 36 KB of RAM. STM32G071CBT6TR requires separate review of its exact pinout, temperature grade, qualification, and software configuration, so it cannot yet be classified as a drop-in replacement.
What are the power and layout considerations for STM32G071KBU6?
The main verified power-layout concern is the 32-UFQFPN exposed pad in a compact 5 x 5 mm package. Place all required bypass capacitors beside their associated supply pins and connect the exposed pad using the manufacturer land-pattern and thermal-copper recommendations. Exact capacitor values, current limits, pin names, and maximum supply ratings are absent from the supplied excerpts and must be taken directly from the full STM32G071KB datasheet and reference design.

Données de référence d'ingénierie pour STM32G071KBU6 — comparaison, recommandations de conception et informations de conformité.

Guide de sélection

Choose STM32G071KBU6 for compact embedded designs that specifically require a verified 64 MHz Arm Cortex-M0+ core, 128 KB of Flash, 36 KB of RAM, four serial communication interfaces, and a 5 x 5 mm UFQFPN package. It is a strong candidate for industrial modules, sensor nodes, building controls, and connected accessories after temperature, analog, timer, and power checks are completed. Related STM32G071 order codes may simplify sourcing, but they should be selected only after memory, qualification, temperature, package, and firmware differences are checked. Avoid cross-brand substitutions unless the supplier provides a verified pin-to-pin MCU with equivalent electrical limits and peripheral behavior. Physical package equality alone is insufficient for a microcontroller replacement.

Principaux différenciateurs

  • 128 KB of Flash supports a larger embedded firmware budget (vs STM32F031K6U6)
  • 64 MHz Cortex-M0+ performance in a compact package (vs STM32F050K6U6A)
  • Four verified serial communication interfaces (vs STM32L151CBU6A)
  • Small 32-UFQFPN footprint with exposed pad (vs STM32G071CBU3)

Notes de conception

Treat the exposed pad as both a manufacturing and thermal feature. Follow the official UFQFPN land pattern exactly, provide solderable copper for assembly, and avoid placing sensitive analog or high-speed signal paths directly beneath uncontrolled pad-planar regions. Keep the exposed-pad via pattern consistent with the manufacturer reference layout and the selected PCB fabricator's assembly process.

Route each required supply branch through low-impedance planes or wide traces and place bypass capacitors close to their associated supply pins. The supplied search excerpts confirm support for 1.8 V, 2.5 V, and 3.3 V levels but do not provide complete decoupling values or absolute electrical limits, so use the manufacturer STM32G071KB datasheet and reference design rather than generic MCU layouts.

Do not treat a related STM32G071 order code as a qualified substitute based only on family name or package shape. Verify memory organization, pin multiplexing, temperature grade, qualification, supply limits, boot behavior, and peripheral mapping. Software migration is also mandatory because physical placement does not guarantee identical peripheral registers, interrupt vectors, or driver support.

Assign high-speed or noise-sensitive interfaces from the verified electrical and alternate-function tables before fixing the PCB footprint. Keep communication traces away from switching nodes and exposed-pad return currents, provide continuous return paths, and validate timing with the selected clock configuration. The compact 5 x 5 mm package limits routing options, so pin multiplexing should be resolved during schematic capture rather than after layout.
