STM32G051K6T6 - 64MHz Cortex-M0+ 32KB MCU | STMicroelectronics
MPN: STM32G051K6T6 ✓ Hoạt độngSTM32G051K6T6 Tóm tắt
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and interface circuitry into one package. The STM32G051K6T6 belongs to the STM32G0 mainstream microcontroller family and uses the low-complexity 32-bit Arm Cortex-M0+ RISC architecture. Its combination of 64 MHz processing performance, 18 KB of SRAM, and embedded peripherals supports responsive control tasks in cost-sensitive industrial, consumer, and communications equipment.
The verified device data identifies a 64 MHz maximum operating frequency, 32 KB of Flash organized as 32K x 8, and 18 KB of SRAM. Two USART peripherals support asynchronous and synchronous serial communication, while the device family also provides general-purpose timers. These resources are useful for sensor acquisition, actuator control, human-interface input, and communication bridges without requiring a separate discrete interface controller.
The 1.7 V to 3.6 V supply range allows operation from low-voltage 3.3 V systems when the supply remains within the documented limits. The STMicroelectronics manufacturer datasheet also explains that VCORE is an internal digital supply produced by an embedded linear voltage regulator. Packages without a dedicated VREF+ pin connect VREF+ internally to VDD and require the internal voltage-reference buffer to remain disabled.
Typical uses include compact motor and relay controllers, industrial sensor nodes, communication modules, USB-connected accessories, instrument-control boards, and low-cost consumer-control products. The 32-pin LQFP package is easy to inspect and rework during prototyping, while the small 7x7 mm body supports space-constrained assemblies when adequate PCB routing and thermal design are provided.
Designers should confirm the exact pin functions, decoupling requirements, clock configuration, flash-programming method, and exposed-pin assignments in the manufacturer datasheet before layout. Software replacement between close STM32G0 devices should be treated as a migration project rather than assumed complete firmware compatibility, even when the package and core match.
This product page consolidates the verified manufacturer and distributor specifications, current ordering information, practical application guidance, and same-family drop-in candidates. It also identifies where alternative sourcing data or detailed electrical characteristics remain unavailable so engineers can validate critical parameters before procurement or design release.

Ứng dụng tiêu biểu
STM32G051K6T6 phù hợp cho 6 Áp dụngs: Industrial Sensor Node, Compact Motor Controller, Serial Communication Bridge, USB-Cowered Peripheral, Timing and Control Module, Consumer Control Product.
Industrial Sensor Node
The STM32G051K6T6 fits compact sensor nodes that acquire measurements, apply filtering, and transmit results over a serial link. Its 64 MHz Arm Cortex-M0+ core provides ample control-processing performance, while 32 KB of Flash and 18 KB of SRAM support an embedded protocol stack, acquisition buffers, and application logic. Two USART channels allow one interface for a sensor or transceiver and another for configuration or diagnostics. Operating from 1.7 V to 3.6 V supports low-power 3.3 V system architectures. The main engineering trade-off is the modest 32 KB code space, which requires attention to library size, bootloader behavior, and future firmware growth.
Compact Motor Controller
The STM32G051K6T6 is suitable for compact motor-control and actuator-control modules where timer accuracy and deterministic control matter more than a high-end processor core. Its 64 MHz Cortex-M0+ platform can execute duty-cycle calculations, commutation logic, and protection routines, and the available general-purpose timers support periodic control tasks. Two USART peripherals can connect a motor module, encoder interface, or tuning interface. The 32-pin LQFP package exposes enough connections for digital control signals while remaining only 7x7 mm. Engineers should add suitable gate drivers, current sensing, fault handling, and thermal protection because the MCU itself does not provide a complete motor-power stage.
Serial Communication Bridge
The STM32G051K6T6 can bridge two serial devices or translate a host protocol when a design needs more than a basic UART converter. With two USART interfaces, the device can manage separate communication endpoints while using its 64 MHz Cortex-M0+ core for framing, buffering, and protocol conversion. The 18 KB of SRAM is useful for temporary frame storage, and the 32 KB of Flash can hold a constrained embedded protocol stack. Its 1.7 V to 3.6 V operating range supports embedded 3.3 V systems. Firmware designers must verify baud-rate margin, interrupt latency, line-driver electrical requirements, and recovery behavior for either communications port.
USB-Cowered Peripheral
The STM32G051K6T6 is appropriate for small USB-powered accessories that use a low-speed or host-capable interface strategy and require local control rather than substantial graphics processing. Its 64 MHz Cortex-M0+ core can manage device enumeration-related tasks, status indicators, and control logic, while two USARTs provide expansion connectivity. The 1.7 V to 3.6 V range can simplify integration into a regulated 3.3 V rail derived from USB power. Its 32 KB Flash and 18 KB SRAM keep the device suitable for focused firmware. Electrical design must still include proper USB data protection, decoupling, power budgeting, and compliance testing rather than treating the MCU as a complete USB peripheral solution.
Timing and Control Module
The STM32G051K6T6 works well for compact timing, monitoring, and event-control modules built around general-purpose timers and a fast 32-bit core. At up to 64 MHz, it can service multiple periodic tasks, calculate intervals, record events, and update outputs without requiring a larger microcontroller. Two USART interfaces allow logging and configuration links, and the 18 KB SRAM can support counters, state machines, and small buffers. The 32-pin LQFP package is particularly accessible for laboratory and low-volume industrial boards. Designers should validate timer clock accuracy against the selected oscillator and reference source, and should confirm worst-case interrupt latency for safety-related timing requirements.
Consumer Control Product
The STM32G051K6T6 supports compact consumer-control products such as appliance interfaces, small keypads, status controllers, and configurable accessory boards. The 64 MHz Cortex-M0+ processor handles user input, debouncing, state management, and serial communication, while 32 KB of Flash and 18 KB of SRAM cover a focused application rather than a rich graphical workload. Two USART channels simplify connection to displays, sensors, or wireless modules. Its 1.7 V to 3.6 V supply range and 7x7 mm LQFP body help reduce board size. Final selection should account for user-interface timing, standby-power targets, production programming, and any consumer-product regulatory requirements.

Ghi chú thiết kế
Decouple VDDA and VDD close to their package pins and follow the manufacturer datasheet for capacitor values, voltage ratings, and startup behavior. The verified operating range is 1.7 V to 3.6 V, but this does not mean every I/O pin can tolerate 5 V. Because VREF+ is internally tied to VDD on packages without a dedicated VREF+ pin, leave the internal voltage-reference buffer disabled as directed by STMicroelectronics.
Reserve clean routing for the 32-pin LQFP footprint, including access to programming and debug signals. Place decoupling capacitance adjacent to supply pins and keep high-current or fast-switching node routing away from sensitive analog inputs. The 7x7 mm package is small enough to make escape routing difficult around fine-pitch leads, so validate the complete layout against the official package drawing and assembly guidelines before fabrication.
Do not treat a same-family MPN change as automatically firmware-compatible. STM32G051K8T6 provides more Flash than STM32G051K6T6, while U6 and T7 order-code suffixes can alter grade-related conditions. Before replacing the part, compare the exact peripheral mix, pin functions, clock limits, flash organization, boot configuration, temperature grade, qualification, and linker settings against the original design.
Plan oscillator, debug, and reset routing from the beginning even when the initial prototype uses an external programmer. The manufacturer datasheet controls oscillator start-up, reset behavior, and alternate-function allocation. Keeping sensitive clock and debug routes short and away from noisy power stages reduces the chance that a layout revision will be required when the design moves from prototype volume to production.
