STM32G031K6T6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
부품 번호: STM32G031K6T6 ✓ 활성STM32G031K6T6 개요
A microcontroller is a semiconductor device that integrates a processor core, programmable memory, data memory, and peripherals on one package. In the STM32G0 product hierarchy, this device belongs to the Arm Cortex-M0+ class of 32-bit RISC microcontrollers and operates within the broader embedded-microcontroller and semiconductor categories. Its combination of 64 MHz processing performance and 32 KB Flash makes it suitable for compact control logic, sensor nodes, communication modules, and cost-sensitive consumer or industrial equipment.
Verified product information identifies 32 KB of Flash, 8 KB of SRAM, two USART peripherals, and a maximum CPU frequency of 64 MHz. The STM32G031K6T6 is available in a 32-pin LQFP package, and distributor listings identify both 2.5 V and 3.3 V operating configurations. The supported supply range is listed as 1.7 V to 3.6 V. Two serial interfaces allow simultaneous debugging or external communications where system architecture and peripheral assignments permit.
The Arm Cortex-M0+ core provides 32-bit processing while retaining the simple instruction set and low implementation complexity associated with Cortex-M devices. Its operating frequency of up to 64 MHz supports responsive control loops, protocol handling, and supervisory tasks without requiring a larger high-performance microcontroller package. The 8 KB SRAM provides working memory for real-time applications, while the 32 KB embedded Flash stores firmware, configuration data, and constant application data.
Typical applications include industrial control modules, building automation endpoints, compact sensor nodes, consumer appliances, battery-powered accessories, and communications equipment. The MCU is especially useful when a board area of 7 x 7 mm is desirable but a high-end Cortex-M processor, large external memory interface, or complex graphics subsystem is unnecessary. Its USART resources can also support host-to-device links, programming interfaces, or field-bus transceiver connections.
Designers should verify the complete pin assignment, peripheral multiplexing, clock configuration, and decoupling requirements against the official STM32G031K6 datasheet before layout release. A 1.7 V to 3.6 V supply must remain within the rated range, and firmware should be validated for startup, brownout behavior, and low-power transitions. Migration to a part with more Flash or RAM can also affect boot space, linker placement, and application layout.
This page consolidates verified manufacturer and distributor information, honest drop-in replacement findings, package-level selection guidance, and practical design considerations. It distinguishes documented STM32G031 family options from unverified cross-brand substitutes so engineers can make a compatibility decision without assuming that equal package size alone guarantees a valid replacement.

일반적인 애플리케이션
STM32G031K6T6 적합 용도: 6 애플리케이션s: Industrial Sensor and Control Module, Battery-Powered IoT Sensor Node, Building Automation Endpoint, Consumer Appliance Controller, Serial Communication Bridge, Compact Power and Charger Controller.
Industrial Sensor and Control Module
The STM32G031K6T6 fits compact industrial sensor and control modules that need deterministic serial communication without the cost of a larger MCU. Its Arm Cortex-M0+ core operates up to 64 MHz, while 32 KB Flash and 8 KB SRAM can hold acquisition logic, configuration handling, and supervisory tasks. The two USART peripherals can connect a local sensor or transceiver while leaving another interface available for diagnostics or programming. Because the verified data does not specify the complete timer or ADC inventory, the design team should confirm peripheral channels, industrial temperature limits, and EMC requirements before schematic approval.
추천
Battery-Powered IoT Sensor Node
The STM32G031K6T6 is suitable for compact battery-powered IoT nodes that periodically acquire data, process it locally, and transmit through a low-power serial link. The 64 MHz Cortex-M0+ core provides useful processing headroom, and the 1.7 V to 3.6 V operating range can simplify matching to low-energy system rails. Two USARTs offer flexibility for a radio or sensor connection and a maintenance interface. Firmware should use the exact STM32G031 low-power behavior verified in the datasheet, while hardware must account for battery impedance, peak radio current, decoupling, and the device's actual quiescent-current specification.
추천
Building Automation Endpoint
The STM32G031K6T6 can serve as the local controller in a compact building-automation endpoint handling switches, inputs, indicators, and serial-connected room equipment. Its 32-bit Cortex-M0+ core operates up to 64 MHz for responsive state-machine and protocol handling, while the two USART peripherals can support downstream controller communication and configuration access. The 7 x 7 mm LQFP footprint reduces board area compared with larger leaded packages. For production use, engineers should verify the available ADC and timer resources, the specified operating-temperature range, and any building-control qualification requirements before treating the MCU as a qualified building-automation device.
추천
Consumer Appliance Controller
The STM32G031K6T6 fits cost-sensitive appliance controls that coordinate buttons, indicators, small motors, and external modules. Its 64 MHz processing rate supports responsive control logic, and 32 KB Flash is suitable for compact application firmware and fixed configuration data. The 8 KB SRAM can support protocol buffers and state management without requiring an external memory device in appropriately sized applications. Two USARTs simplify diagnostic or module connectivity. Because the verified source does not specify motor outputs, PWM channels, ADC resolution, or operating-temperature limits, those functions and protection requirements must be confirmed from the complete manufacturer datasheet before layout.
추천
Serial Communication Bridge
The STM32G031K6T6 is well matched to a small protocol-conversion or service interface because it provides two USART peripherals and an Arm Cortex-M0+ core operating up to 64 MHz. One serial channel can face an external controller while the other connects a sensor, transceiver, or configuration port. The 32 KB Flash capacity accommodates protocol state machines and firmware, while 8 KB RAM supports packet handling. Pin multiplexing, peripheral instance availability, baud-rate tolerance, and electrical levels must be checked against the exact package pinout. External ESD, isolation, logic-level, and connector requirements depend on the application environment.
추천
Compact Power and Charger Controller
The STM32G031K6T6 can support supervisory or power-management functions in compact battery and charger subsystems. Its 1.7 V to 3.6 V supply range is compatible with low-voltage rails, and the 64 MHz core can execute control algorithms, state management, and fault handling. Two USARTs can connect a host or fuel-gauge interface. The MCU is a controller rather than a dedicated power converter, so designers must establish separate power-path, switching-device, current-sense, and protection architecture. Exact ADC channels, timer outputs, analog limits, and low-power wake behavior must be confirmed from the official datasheet before assigning safety- or regulation-critical functions.

설계 노트
Design the supply for the verified 1.7 V to 3.6 V operating range, including both 2.5 V and 3.3 V system configurations. Place the manufacturer's recommended bypass capacitors close to the supply and ground pins, and validate startup behavior across the full supply range. Because the verified excerpts do not provide current consumption or power-loss behavior, obtain those values from the official datasheet before sizing the regulator, battery, or energy-storage components.
Use the STM32G031K6 32-pin LQFP land pattern rather than selecting a footprint only by pin count. Verify pin 1 orientation, exposed thermal considerations, solder-mask limits, and paste-land geometry against the official package drawing. Keep SWD programming access accessible, maintain short return paths for decoupling, and place input protection close to connectors. Do not substitute a QFN or alternate-package STM32G031 variant without a PCB redesign.
Do not treat a larger-memory STM32G0 device as a guaranteed drop-in replacement merely because both use a 32-pin LQFP. The STM32G031K8T6 and STM32G030K8T6 candidates provide 64 KB Flash rather than 32 KB and may differ in peripheral configuration, clock implementation, low-power behavior, or device identification. Compare the complete pin tables and reference manual sections, then recompile and validate the firmware, startup code, bootloader, and linker configuration.
Keep the 7 x 7 mm LQFP perimeter accessible for inspection, rework, and programming access. Route sensitive analog or communication signals away from fast digital edges and noisy switching nodes, while following the manufacturer's decoupling guidance. If the board combines the MCU with a switching regulator, radio, or motor driver, separate high-current paths and provide a quiet ground strategy. Exact high-speed timing and analog-layout recommendations require the complete peripheral and electrical specifications from the manufacturer documentation.
규정 준수 정보
The supplied manufacturer and distributor excerpts do not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred from the STM32G0 family name.
