STM32G071KBT3 - 64MHz Cortex-M0+ MCU, 128KB Flash | STMicroelectronics
Teilenummer: STM32G071KBT3 ✓ AktivSTM32G071KBT3 Übersicht
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The STM32G0 family belongs to the Arm Cortex-M0+ class of 32-bit embedded processors. These devices are used as the central controller in products that require deterministic control, serial communication, analog measurement, or programmable output, including industrial controls, consumer equipment, sensors, and connected products.
The STM32G071KBT3 provides 64 MHz processing performance for responsive control loops and efficient protocol handling. Its 128 KB of Flash supports firmware and application code, while 36 KB of RAM supports working data, buffers, and stacks. The 1.7 V to 3.6 V operating range allows operation from common low-voltage rails, and integrated ADC and DAC functions can reduce the number of external components in measurement and signal-generation designs.
The device includes four USARTs, timer resources, analog conversion functions, and multiple communication interfaces. These resources make the microcontroller suitable for applications requiring several serial links, motor or actuator control, sensor acquisition, embedded user interfaces, or connected industrial equipment. The 32-LQFP package exposes the necessary I/O and power connections in a compact surface-mount format suitable for automated assembly.
Designers should confirm the exact peripheral mapping, electrical limits, pin multiplexing, clock tree, and startup configuration against the STM32G071KB datasheet before layout release. The operating-voltage range must be respected for every external interface, and unused pins should be configured according to the device guidelines rather than left without a defined state.
This product page combines manufacturer specifications with practical implementation guidance for firmware, analog signal conditioning, interface routing, and package-aware sourcing. It also helps engineers distinguish the exact STM32G071KBT3 orderable device from related STM32G071 variants whose pin count, memory configuration, temperature grade, or ordering suffix may differ.

Auswahlhilfe
Wichtigste Unterscheidungsmerkmale
- Four integrated USART peripherals support multi-link embedded designs (vs. STM32G071 variants with fewer serial peripherals)
- Integrated ADC and DAC reduce external analog-helper components (vs. Discrete ADC or DAC implementations)
- Compact memory configuration fits embedded control in a 32-LQFP package (vs. Larger-pin-count STM32G071 variants)
Designhinweise
Design the supply network around the manufacturer-specified 1.7 V to 3.6 V operating range. Confirm each peripheral's voltage tolerance, use a regulator with adequate margin, and decouple the MCU supply pins according to the STM32G071KB guidance. Do not assume that every 3.3 V peripheral signal is automatically safe for every powered state; include the required sequencing and reset behavior in the system schematic.
Transcribe all 32 pins directly from the STM32G071KB pin-description table and alternate-function mapping. Route SWD programming and debug signals, clock inputs, reset, and decoupling connections according to the reference layout. Keep sensitive analog inputs away from fast-switching nodes where possible, and provide clean return paths so ADC and DAC performance is not undermined by board-level return currents.
Do not substitute an STM32G071 code solely because its flash and RAM sizes look similar. Pin count, pin multiplexing, peripheral inventory, package dimensions, voltage range, and temperature grade can differ among order codes. Validate the exact suffix, complete pin table, device marking, and firmware target before releasing a replacement to production.
Place the required input and output capacitors close to their respective pins, with short ground returns and the smallest practical loop area. Follow the manufacturer's recommended component placement and exposed thermal-management guidance for the LQFP package. If the 64 MHz operating point creates significant switching activity, isolate analog routing and provide an uninterrupted ground reference beneath the relevant circuitry.
Compliance-Informationen
