STM32G041K6T6 - 64MHz Cortex-M0+ 32KB MCU | STMicroelectronics
部品番号: STM32G041K6T6 ✓ 生産中STM32G041K6T6 概要
A microcontroller is the central programmable component of an embedded system, combining a processor core, nonvolatile program memory, volatile data memory, and peripherals on one semiconductor die. The STM32G041 belongs to the STM32G0 family, a low-power Arm Cortex-M0+ product hierarchy positioned for cost-sensitive, high-volume control and IoT applications. Its low operating-voltage range also supports energy-conscious designs using standard low-voltage supply rails.
Key features include a 64 MHz Arm Cortex-M0+ core, 32 KB of Flash, 8 KB of SRAM, two USART peripherals, a 12-bit ADC, and AES-256 hardware encryption. These resources support serial-connected sensors, compact user interfaces, motor-control monitoring, and secure device communication. The 32-pin LQFP package provides enough I/O for external transceivers, analog inputs, programming access, and mixed-signal peripherals while remaining compatible with conventional leaded-assembly processes.
The STM32G0 architecture emphasizes efficient embedded processing while retaining familiar Arm Cortex-M programming conventions. Its clocking and peripheral resources support designs that balance responsiveness with low power, while the integrated analog and communications blocks reduce the need for external components. The 1.7 V to 3.6 V operating range makes the device suitable for 1.8 V, 2.5 V, and 3.3 V system rails, provided each selected external component shares the appropriate voltage tolerance.
Typical applications include IoT sensor nodes, digital thermometers, compact motor controllers, building-control modules, communication transceivers, and low-power consumer products. A two-USART configuration is useful for local debugging or connecting a wireless module, while the ADC supports battery, temperature, or analog-sensor monitoring. The AES-256 accelerator can improve cryptographic throughput when a connected product requires hardware-assisted encryption.
Designers should verify pin multiplexing, peripheral conflicts, clock-tree requirements, and decoupling using the manufacturer datasheet before PCB release. The 32-pin LQFP footprint simplifies hand soldering and automated through-hole assembly, but exposed thermal performance still depends on copper routing, airflow, and the selected power dissipation profile.

主な用途
STM32G041K6T6 の用途: 6 件s: Industrial IoT Sensor Node, Digital Thermometer and Environmental Monitor, Compact Motor Monitoring Controller, Battery-Powered Condition Monitoring, Building Control and Automation Module, Secure Connected Embedded Device.
Industrial IoT Sensor Node
The STM32G041K6T6 fits compact sensor nodes because its 64 MHz Arm Cortex-M0+ core can process measurements while the 8 KB SRAM handles protocol state and short data buffers. The 12-bit ADC supports analog sensing, and two USARTs can connect a wireless module while retaining a separate diagnostic interface. Operating from 1.7 V to 3.6 V allows deployment on 1.8 V, 2.5 V, or 3.3 V rails. The main design trade-off is limited Flash capacity, so firmware must avoid large local buffering and unnecessary middleware.
おすすめ
Digital Thermometer and Environmental Monitor
A digital thermometer can use the STM32G041K6T6 for sensor conversion, filtering, display updates, and digital communications. The 12-bit ADC is suitable for analog temperature elements or resistive sensor networks, while the 64 MHz core provides margin for calibration and interface handling. Its 8 KB SRAM is sufficient for compact data-processing tasks, and the two USARTs can support a display bridge or external sensor connection. Low-power behavior must be configured by disabling unused clocks and peripherals between measurements.
おすすめ
Compact Motor Monitoring Controller
The STM32G041K6T6 can supervise a small motor system by sampling current or temperature through the 12-bit ADC and coordinating timing functions through its timer resources. The 64 MHz processor supports responsive control and fault-handling logic, while the 1.7 V to 3.6 V range supports low-voltage systems. The MCU should not drive motor power directly; designers still need a suitable gate driver or H-bridge, current sensing, and protection. Firmware review must confirm that every required timer output and ADC input maps to the available LQFP pins.
おすすめ
Battery-Powered Condition Monitoring
The STM32G041K6T6 is appropriate for remote equipment monitoring where a modest processing footprint and low-voltage operation are important. The 32 KB Flash supports focused firmware, the 8 KB SRAM avoids requiring an external memory device, and the ADC can measure battery voltage or sensor inputs. Two USARTs provide flexible connectivity to a radio or service interface. For battery life, use the MCU's low-power operating modes, disable unused peripheral clocks, and select external sensors with compatible low-current behavior and shutdown modes.
おすすめ
Building Control and Automation Module
The STM32G041K6T6 can serve as the local controller in a building-automation module that reads analog inputs and communicates over serial networks. Its 64 MHz Cortex-M0+ core handles protocol and state-machine tasks, while two USARTs support isolated communications or service debugging. The 32-pin LQFP package provides a practical balance between I/O access and assembly simplicity. Industrial deployments should add appropriate transient protection, isolation, and power conditioning outside the MCU, and should verify timer and communication pin multiplexing before layout approval.
おすすめ
Secure Connected Embedded Device
The STM32G041K6T6 is suited to compact connected products that require hardware-assisted secure data handling. Its AES-256 accelerator can offload cryptographic processing from the Cortex-M0+ core, improving responsiveness when protecting commands, credentials, or transported data. The two USARTs and 12-bit ADC support communication and local monitoring, and the 1.7 V to 3.6 V range supports common low-voltage rails. Hardware acceleration does not replace a complete security architecture, so developers must still implement key management, authenticated protocols, secure boot where required, and secure firmware-update procedures.

設計ノート
Check all device and peripheral operating limits against the selected supply rail. The STM32G041K6T6 supports a 1.7 V to 3.6 V range, but connected sensors, transceivers, pull-ups, and regulators must also support that voltage. Place the manufacturer's recommended input, output, and bypass capacitors close to their pins, and keep high-current return paths away from sensitive analog inputs.
Use the package drawing and pin-description table in the manufacturer datasheet to assign every LQFP pad. Verify alternate-function multiplexing for ADC inputs, USART signals, timer channels, debug functions, and programming pins before routing. Maintain clear copper around exposed analog and power pins, provide a low-impedance ground reference, and use test points that do not compromise signal integrity.
Do not assume that two same-package STM32G0 devices are interchangeable. Compare clock limits, peripheral instances, pin remapping, memory organization, boot behavior, and firmware support between the STM32G041K6T6 and its candidate. Also distinguish the 32-pin LQFP option from smaller UFQFPN or other package suffixes, because their land patterns and exposed-pad requirements are different.
The 32-pin LQFP provides adequate thermal spreading for many low-power IoT and control designs, but the actual junction temperature depends on supply voltage, I/O activity, clock rate, ambient temperature, and board construction. Avoid adding copper or changing clock assumptions without checking the electrical limits. For sustained high activity, use a multilayer board with an uninterrupted ground plane and calculate the thermal rise using the package and board-specific thermal information.
