STM32G041K8U6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
部品番号: STM32G041K8U6 ✓ 生産中STM32G041K8U6 概要
A microcontroller, or MCU, is a semiconductor that integrates a processor core, memory, and peripherals into one device. The STM32G0 MCU family belongs to the embedded-controller hierarchy, combining an Arm Cortex-M0+ core with timers, communication interfaces, analog conversion functions, and general-purpose I/O. This integration reduces component count and simplifies firmware-based measurement, monitoring, and control designs.
Key features of the STM32G041K8U6 include a 64 MHz maximum CPU frequency, 64 KB of programmable Flash, 8 KB of SRAM, and two USART interfaces. The STM32G041x6/x8 family is specifically positioned for cost-sensitive applications combining an MCU, ADC, timer, and PWM functions. Its small 5 x 5 mm UFQFPN package also supports space-constrained control boards.
The Cortex-M0+ processor provides a compact instruction set with Thumb-2 support and deterministic behavior suitable for embedded control. Flash memory retains firmware when power is removed, while SRAM provides working memory for execution stacks, data buffers, and control algorithms. The peripheral set supports communication with external controllers and the generation of precision timing or PWM waveforms for actuator and power-conversion systems.
Typical applications include industrial sensor nodes, compact motor controllers, digital power conversion, battery-powered instruments, building-control modules, and low-cost consumer devices. The combination of 64 MHz processing, 8 KB RAM, analog functions, timers, PWM, and serial communication allows one MCU to supervise multiple mixed-signal tasks without external logic devices.
PCB design should follow the manufacturer’s pin and land-pattern requirements exactly, including exposed-pad and thermal-via layout. Place decoupling capacitors adjacent to the supply pins, route sensitive analog inputs away from fast-switching nodes, and confirm the selected temperature and order-code requirements against the manufacturer datasheet before production release.
This product page combines the manufacturer’s device positioning, package and memory details, sourcing guidance, application fit, and design cautions into a practical engineering overview for the STM32G041K8U6. It also identifies family-level alternatives for designs that require different flash density, memory, or peripheral resources while retaining the same 32-pin footprint.

主な用途
STM32G041K8U6 の用途: 6 件s: Compact Industrial Sensor Nodes, Motor Control and PWM Systems, Digital Power Conversion Control, Battery-Powered Measurement Instruments, Building Control and HVAC Modules, Access Control and Security Peripherals.
Compact Industrial Sensor Nodes
The STM32G041K8U6 fits compact sensor nodes because its 64 MHz Arm Cortex-M0+ core, 64 KB of Flash, and 8 KB of SRAM can supervise acquisition, filtering, and local control functions. Two USART interfaces support serial sensors or links to a gateway without consuming several external interface devices. The 32-pin 5 x 5 mm UFQFPN package also preserves board area in distributed instrumentation. Confirm the exact ADC resolution, input count, timer channels, and supply limits against the manufacturer documentation before selecting input ranges or sampling schedules.
おすすめ
Motor Control and PWM Systems
The STM32G041K8U6 is suitable for timer-driven motor and solenoid-control systems because it combines a deterministic 64 MHz Cortex-M0+ core with mixed-signal and PWM-oriented resources. The 8 KB of SRAM can support control state, timing variables, and modest communication buffers, while 64 KB of Flash accommodates application firmware and parameter tables. Its 5 x 5 mm package allows placement near power stages and current-feedback networks. Validate timer channel mapping, complementary outputs, ADC trigger behavior, and fault-response timing before committing the control loop.
おすすめ
Digital Power Conversion Control
The STM32G041K8U6 can serve as the digital controller in compact power-conversion products where deterministic PWM generation, analog monitoring, and serial adjustment are required. Its 64 MHz processing rate provides headroom for closed-loop calculations, while two USARTs can support configuration or supervisory communication. The small UFQFPN footprint helps reduce controller-board size around MOSFET drivers and power-stage components. Confirm PWM frequency, timer resolution, ADC latency, compensation requirements, and start-up behavior in the manufacturer datasheet before defining the control loop.
おすすめ
Battery-Powered Measurement Instruments
The STM32G041K8U6 is appropriate for compact battery-powered instruments that combine sensing, display or data handling, and serial communication in one device. Its 64 KB of Flash and 8 KB of SRAM support embedded firmware, calibration tables, working buffers, and communication routines without requiring external memory. The 32-pin package simplifies integration into handheld or portable enclosures, while the Cortex-M0+ core provides deterministic real-time behavior. Power-budget calculations should use the device’s actual sleep, run, and peripheral currents from the manufacturer documentation for the selected operating mode.
おすすめ
Building Control and HVAC Modules
The STM32G041K8U6 can support distributed HVAC and building-control modules that monitor inputs, drive valves or relays through timers, and report status over serial links. Its 64 MHz Cortex-M0+ core handles protocol timing and control logic, while the two USARTs can connect to local sensors or an upstream controller. The compact 5 x 5 mm UFQFPN package is useful behindDIN-rail or wall-control housings with limited board area. Verify logic thresholds, exposed-pad connections, transient immunity, and peripheral assignments before industrial certification testing.
おすすめ
Access Control and Security Peripherals
The STM32G041K8U6 is suitable for compact access-control readers, credential readers, and local security peripherals that require deterministic control and serial communication. Its 64 KB of Flash supports embedded control firmware, while 8 KB of SRAM accommodates communication frames and short-lived state buffers. The 32-pin package allows the controller to fit beside a reader, keypad, indicator, or communications transceiver. Security implementations must add the appropriate hardware root of trust, key storage, tamper response, and secure update procedure rather than relying on firmware alone for cryptographic protection.

設計ノート
Follow the manufacturer’s 32-pin UFQFPN land-pattern and exposed-pad requirements exactly. Place the required input, output, and bypass capacitors adjacent to their corresponding pins, and use short ground returns. Treat the exposed pad as both an electrical and thermal connection according to the pin-description table. Incorrect pad assignment or an unintended ground connection can affect operation as well as soldering yield.
Build the power budget from the actual operating mode rather than the maximum CPU frequency alone. Account for the core, peripherals, analog circuitry, GPIO loads, and external sensor current. Apply the manufacturer’s recommended operating voltage range to the selected package and temperature grade, and verify brownout behavior if the product must preserve state during slow supply transitions.
Keep analog inputs, voltage references, and sensitive digital interfaces away from high-current switching paths. Use a continuous ground plane where practical, but split analog and digital return paths only according to a validated grounding strategy. For PWM-controlled power stages, inspect switching-edge coupling at the MCU pins and include filtering where the application noise budget requires it.
Do not treat a shared UFQFPN footprint as proof of functional interchangeability. Before substituting an STM32G0 device, compare pin multiplexing, Flash, SRAM, timer assignments, ADC channels, USART features, clock limits, and exposed-pad connectivity. Then recompile the firmware, retest timing, and verify all production programming and boundary-condition tests.
