STM32G071CBT6 - 64MHz Cortex-M0+ 128KB MCU | STMicroelectronics
MPN： STM32G071CBT6 ✓ 啟用中STM32G071CBT6 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device used to read sensors, control outputs, execute embedded software, and manage system communications. The STM32G0 family belongs to the STM32 family and uses the Arm Cortex-M0+ processor architecture, a low-complexity 32-bit core designed for resource-constrained embedded systems.
Verified product information identifies the STM32G071CBT6 as a 32-bit, 64 MHz device with 128 KB Flash organized as 128K x 8. The supplied data does not specify RAM size, voltage range, peripheral inventory, pin assignments, temperature range, or package dimensions beyond the stated 48-LQFP 7x7 mm format; those values must be confirmed in the manufacturer documentation before design release.
The STM32G071CBT6 is positioned as a mainstream microcontroller for embedded control rather than a high-performance application processor. Its 64 MHz Cortex-M0+ core provides a defined timing basis for motor, control, sensor-processing, and communication-oriented firmware. Because the supplied source does not provide detailed peripheral specifications, engineers should verify ADC, timer, UART, SPI, I2C, USB, and GPIO resources directly against the official STM32G071x8/xB documentation.
Typical design uses include small industrial automation modules, digital sensor controllers, building and access-control peripherals, low-speed communication gateways, and compact consumer equipment. The 48-LQFP package exposes more pins than a small QFN package and can simplify assembly where leaded soldering or inspection is preferred.
A key engineering consideration is firmware and peripheral migration. Before replacing an existing STM32 design, verify startup files, memory organization, pin multiplexing, clock settings, peripheral instances, and package-specific land patterns. The part number and package must be treated as exact BOM identifiers, not inferred from a similar STM32G0 device.
This product page combines the verified manufacturer identity, distributor listing, package information, source links, and practical design guidance. It does not invent missing electrical, pinout, pricing, or compliance values; those fields remain explicitly marked when the supplied evidence is incomplete.

典型應用
STM32G071CBT6 適用於 6 應用s: Compact Industrial Automation Controller, Digital Sensor and Measurement Node, Low-Speed Communication Gateway, Access-Control and Security Peripheral, Consumer Appliance Embedded Controller, Educational and Prototype MCU Platform.
Compact Industrial Automation Controller
STM32G071CBT6 fits a compact automation controller when the design needs a 64 MHz Cortex-M0+ execution target, 128 KB of application Flash, and a leaded 48-LQFP package that is practical for inspection and rework. The MCU can supervise digital inputs, drive outputs, run state-machine logic, and coordinate sensors or actuators. Its 128 KB Flash provides a defined code-storage budget for control routines, while the 48-LQFP footprint exposes more package pins than a small QFN. Before release, verify supply voltage, temperature range, ADC performance, timer resources, communications, and ESD requirements against the official STM32G071x8/xB documentation.
推薦
Digital Sensor and Measurement Node
The STM32G071CBT6 can serve as the local controller in a digital sensor node where firmware must sample inputs, apply calibration, filter readings, and present data through a serial interface. Its verified 64 MHz Cortex-M0+ core and 128 KB Flash provide a clear baseline for embedded measurement logic, while the 48-LQFP package supports conventional board assembly. The supplied sources do not confirm the ADC resolution, sampling rate, sensor interfaces, or analog supply limits, so those specifications must be checked before assigning an analog sensor directly to the MCU. External signal conditioning, protection, and reference design may still be required.
推薦
Low-Speed Communication Gateway
STM32G071CBT6 is suitable for a small protocol gateway or communications controller when the application uses deterministic embedded firmware and does not require resources outside the verified STM32G0 family specification. The 64 MHz core can handle protocol state machines, buffering, diagnostics, and supervisory logic, while 128 KB Flash stores application code. The supplied evidence does not list UART, SPI, I2C, USB, Ethernet, or other interface details, so engineers must verify the required peripheral instance count and pin multiplexing in the official datasheet. A gateway design should also account for transceiver supply, signal termination, and protocol timing.
推薦
Access-Control and Security Peripheral
The STM32G071CBT6 can be evaluated for access-control peripherals, keypad scanners, relay controllers, and compact security modules where a 32-bit Cortex-M0+ core and 128 KB Flash are sufficient. Firmware can manage inputs, debounce user interfaces, drive lock or alarm outputs, and record diagnostic events. The verified evidence does not establish security certification, cryptographic hardware, operating-temperature limits, or EMC qualification. Those requirements must be checked explicitly for the final product. Because the MCU is in a leaded 48-LQFP package, it is also practical where visual solder inspection is preferred over a leadless package.
推薦
Consumer Appliance Embedded Controller
STM32G071CBT6 can be used in a compact appliance controller when the product needs local logic for user inputs, motors, displays, relays, or simple sensor systems. The verified 64 MHz operating speed and 128 KB Flash leave a defined baseline for an embedded state machine and application firmware, while the 48-LQFP package supports straightforward board bring-up and repair. The supplied data does not confirm the exact pin multiplexing, peripherals, voltage range, or temperature range, so a consumer design should not be released without checking the official documentation. External drivers and protection networks may be needed for motors, heaters, displays, or mains-connected interfaces.
推薦
Educational and Prototype MCU Platform
STM32G071CBT6 is well suited to an educational or prototype platform because it combines an Arm Cortex-M0+ core, a 64 MHz maximum frequency, 128 KB Flash, and a conventional 48-LQFP package. Students and engineers can develop firmware for timers, serial links, digital I/O, and basic control experiments while retaining a clear upgrade path within the STM32 ecosystem. The exact peripheral inventory and development-board support are not established by the supplied data. Before purchasing boards or writing production-oriented firmware, verify the package pinout, clock configuration, debug interface, bootloader behavior, and available peripheral resources in the official STMicroelectronics documentation.

主要差異化特點
- Verified 64 MHz Cortex-M0+ performance target (對比STM32F030C6T6)
- Explicit 128 KB Flash allocation (對比STM32F042C4T6)
- Verified 7x7 mm 48-LQFP format (對比STM32G071CBT3TR)
設計說明
Before assigning power rails or external drivers, verify the STM32G071CBT6 operating-voltage range, absolute maximum ratings, and supply sequencing from the official manufacturer documentation. The verified data confirms 64 MHz operation and 128 KB Flash but does not provide voltage limits. Confirm the core and I/O voltage conditions at the selected clock, then size decoupling and protection networks around the actual rails used by the design.
Use the exact 48-LQFP package drawing and land pattern for STM32G071CBT6; do not substitute a generic 48-pin footprint without checking body size, lead pitch, pin numbering, and solder mask clearance. Keep decoupling components close to the corresponding supply pins, preserve the exposed copper needed for the device's thermal design if applicable, and route high-current or sensitive signals away from clock and debug nets. Because the supplied evidence does not include the pinout, all net assignments must be checked against the manufacturer drawing.
Do not assume that a similarly named STM32F030 or STM32F042 device is a drop-in replacement. Memory sizes, peripheral instances, clock trees, alternate-function mappings, and package details can change across STM32 families. Treat STM32G071CBT3TR, STM32F030C6T6, STM32F042C4T6, STM32F030C8T6TR, and STM32F030CCT6TR as comparison candidates only until the official pinout, electrical limits, boot behavior, and firmware requirements are independently verified.
Plan the debug and programming interface from the official STM32G071CBT6 documentation before placing connectors. Place test points, reset circuitry, clock components, and decoupling where they remain accessible during board bring-up. For mixed-signal or sensor nodes, separate analog and digital return paths where practical and keep external switching or high-current traces away from sensitive input routing. The supplied data does not specify the alternate-function pin map, so layout sign-off must use the official datasheet.
合規資訊
The supplied verified sources identify the manufacturer and product listing but do not provide compliance certificates or declarations. Compliance fields must be confirmed with STMicroelectronics or an authorized distributor.
