STM32G031K4T6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
部品番号: STM32G031K4T6 ✓ 生産中STM32G031K4T6 概要
A general-purpose microcontroller is a programmable semiconductor that combines a processor core, nonvolatile program memory, volatile data memory, and peripherals in one integrated circuit. The STM32G031K4T6 belongs to the STM32G0 microcontroller family and sits within the hierarchy of embedded processor, microcontroller, and semiconductor. Its Arm Cortex-M0+ architecture supports efficient event-driven control while keeping the external hardware count low.
The device's principal features include a 64 MHz CPU, 16 KB Flash, 8 KB SRAM, two USART interfaces, an analog-to-digital converter, timers, and communication interfaces. The 16 KB Flash supports a modest embedded application, while 8 KB of SRAM provides working space for control logic, communication buffers, and stack operations. A 1.7 V minimum operating voltage allows use in low-voltage systems, although the complete design must remain within the 1.7 V to 3.6 V operating range.
The STM32G0 series combines an Arm Cortex-M0+ core with integrated analog and communications resources in a compact package. Two USARTs permit simultaneous serial-device connections, while the ADC allows the MCU to measure analog inputs without a separate converter. General-purpose timers support periodic timing, input capture, output compare, and basic motor-control or signal-generation functions. Firmware can use these peripherals to create responsive embedded systems with fewer external components.
Typical applications include compact sensor nodes, industrial condition-monitoring equipment, small motor controllers, digital control panels, serial data concentrators, and low-power IoT devices. The 32-pin LQFP package remains inspectable after soldering and is practical for prototypes, small production runs, and designs that favor through-hole access over the smallest possible land pattern.
When laying out the PCB, place decoupling capacitors close to the power pins and route oscillator, reset, and communications signals away from noisy switching nodes. Confirm pin multiplexing in the device pinout and pin-description table before assigning alternate functions. Firmware and peripheral configuration should follow the STM32G0 reference manual and device programming guidance rather than assuming that compatibility with an older STM32 series extends to every peripheral register.
This product page combines manufacturer and distributor identification, verified memory and operating information, practical application guidance, same-package alternatives, and engineering-focused design notes. Those details help engineers distinguish a true package-compatible substitution from a merely similar microcontroller before committing a PCB revision or production BOM.

主な用途
STM32G031K4T6 の用途: 6 件s: Industrial Condition Monitoring, Low-Power IoT Sensor Nodes, Compact Motor and Actuator Control, Serial Data Concentrator, Digital Control Panel and Interface, Small Motor-Control Learning Platform.
Industrial Condition Monitoring
The STM32G031K4T6 fits compact condition-monitoring modules that collect vibration, temperature, or equipment-state information and report it over serial links. Its 64 MHz Cortex-M0+ core provides responsive filtering and control, while 8 KB of RAM accommodates working buffers for sampled data. The two USARTs allow simultaneous use of an industrial sensor interface and an external communications link. Operating from 1.7 V to 3.6 V also supports low-voltage sensing nodes. Place local decoupling near the supply pins and confirm that the selected analog and serial functions remain available on the 32-pin LQFP pin assignments.
おすすめ
Low-Power IoT Sensor Nodes
The STM32G031K4T6 supports compact IoT sensor nodes where a 16 KB firmware area and 8 KB of RAM are sufficient for local measurement, status logic, and short protocol handling. Its 1.7 V minimum operating voltage is useful for low-energy sensor assemblies, while the ADC processes analog inputs without requiring a separate converter. Two USART interfaces provide options for a sensor bus and a host or radio link. Firmware should use the STM32G0 low-power modes and peripheral settings documented by STMicroelectronics to obtain the intended duty-cycle behavior, and the PCB should reserve a clean low-noise path for the analog supply when measurements require it.
おすすめ
Compact Motor and Actuator Control
The STM32G031K4T6 is appropriate for small motor, valve, or actuator controllers where embedded control must coexist with serial configuration and diagnostic communication. Timers support repeatable timing and edge-sensitive control functions, while the 64 MHz CPU leaves room for a state machine and protection logic within the 16 KB Flash limit. The ADC can monitor current, position, or supply feedback if the selected board exposes the required channels. Two USARTs permit one connection for tuning or diagnostics and another for system integration. Validate PWM or capture routing against the 32-pin pinout, include appropriate driver isolation, and provide local bulk and high-frequency decoupling around the MCU and power stage.
おすすめ
Serial Data Concentrator
The STM32G031K4T6 can act as a small serial concentrator when two UART-connected devices must feed a local controller or protocol bridge. Its two USARTs provide separate serial channels, and 8 KB of RAM can support modest frame handling and buffering. The 64 MHz Cortex-M0+ core is suitable for deterministic format conversion, command parsing, and status aggregation without a complex external processor. The 32-pin LQFP footprint supports accessible assembly and prototype rework. Engineer the UART levels for each connected device, isolate long cables with suitable protection, route serial signals away from switching nodes, and verify that baud-rate accuracy and peripheral clock configuration meet the required timing margin.
おすすめ
Digital Control Panel and Interface
The STM32G031K4T6 fits compact digital control panels that coordinate button input, indicators, displays, and serial configuration. Its timers and GPIO resources support periodic scanning, debouncing, indicator timing, and interface updates, while the ADC can monitor analog control or feedback signals. Sixteen kilobytes of Flash is appropriate for a focused user-interface firmware rather than a graphics-heavy interface. Two USARTs can serve an external display or configuration port and a service interface. Place the MCU and its bypass network away from display and switching-supply return currents, use an appropriate ESD strategy for user-accessible connections, and validate pin multiplexing before finalizing the PCB footprint.
おすすめ
Small Motor-Control Learning Platform
The STM32G031K4T6 is well suited to compact motor-control education and prototyping because it combines a 64 MHz Cortex-M0+ core, timers, ADC, and serial communication in one accessible 32-pin LQFP package. Engineers can use the two USARTs for console output and a control interface while implementing timing, pulse-width modulation, and basic feedback algorithms. The 16 KB Flash limit encourages focused example firmware and straightforward task division. Development boards should provide accessible programming and debug connections, motor-driver isolation, current limiting, and a removable power section. Before moving beyond a demonstration, validate worst-case timing, thermal behavior of the driver, and startup conditions under realistic mechanical load.

設計ノート
Place the required supply bypass capacitors directly beside the STM32G031K4T6 power pins, with the shortest possible ground return paths. Keep the 3.3 V and low-voltage analog routing away from switching-node copper and high-current return paths. Because the device supports operation down to 1.7 V, verify regulator startup, voltage tolerances, and I/O levels rather than treating 3.3 V as an unconditional requirement.
Assign every external connection from the numbered 32-pin LQFP pinout and alternate-function table before schematic release. Pay particular attention to debug, programming, oscillator, reset, and USART pins because their available functions can vary by package and ordering code. Preserve test-point access where possible, and route oscillator traces away from UART and switching-supply nodes to reduce susceptibility to timing and communication errors.
A same-footprint STM32G0 alternative is not automatically a firmware-compatible replacement. The K4 and K8 ordering codes differ in Flash capacity, while temperature-grade suffixes change the environmental grade. Rebuild the linker configuration for a different Flash size, review the startup vector table and bootloader assumptions, and compare electrical limits. For a cross-family MCU, validate every peripheral mapping and communication protocol.
The 1.7 V to 3.6 V operating range does not remove the need for careful power sequencing. Confirm that the MCU supply, reset state, and connected peripherals remain valid through power-up and power-down. Use brownout and reset behavior from the manufacturer reference documentation, and avoid allowing externally powered UART or sensor interfaces to back-power an unpowered MCU unless the interface device explicitly supports that condition.
