STM32G041C8U6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
部品番号: STM32G041C8U6 ✓ 生産中STM32G041C8U6 概要
A microcontroller integrates a processor core, program memory, data memory, peripherals, and I/O into one device. The Cortex-M0+ architecture provides a compact instruction set suited to real-time control, while the STM32G0 family extends into the broader hierarchy of embedded processor, microcontroller, semiconductor, and embedded systems products. This combination makes the STM32G041C8U6 appropriate for compact control boards, industrial sensing nodes, and connected equipment.
The device operates at up to 64 MHz and includes 64 KB of Flash program memory alongside 8 KB of SRAM. Its 48-pin UFQFPN package provides a surface-mount implementation with an exposed pad for PCB-level thermal management. The part is identified as a mainstream STM32G0 device, positioning it for applications that need modern Cortex-M0+ performance without moving to a higher-cost microcontroller family.
According to the manufacturer datasheet, the STM32G041x6/x8 devices use an Arm Cortex-M0+ 32-bit RISC core. The exact peripheral mix, voltage limits, conversion performance, and absolute maximum ratings must be taken from the package-specific datasheet and pinout tables before a design is released. The manufacturer also documents package-dependent handling of VREF+, including its internal connection to VDD when the package does not provide a dedicated VREF+ pin.
Typical uses include compact motor-control controllers, industrial sensor interfaces, digital monitoring equipment, and low-cost IoT control nodes. Its small surface-mount package supports automated assembly, while the Cortex-M0+ ecosystem provides access to STM32 development tools, embedded software libraries, and familiar firmware-development workflows.
PCB design should treat the exposed pad as a thermal and electrical structure rather than an unused area. Follow the manufacturer’s recommended land pattern, connect the ground network properly, and verify decoupling, debug-port, clock, and boot configuration requirements against the package pinout. Confirm peripheral assignments and startup behavior in the device reference manual.
This product page combines the exact orderable MPN, manufacturer specifications, package information, verified source links, comparison data, and practical integration guidance. It also distinguishes confirmed device facts from parameters that require selection from the complete datasheet, helping engineers move from component identification to a production-ready embedded design.

主な用途
STM32G041C8U6 の用途: 6 件s: Compact Industrial Sensor Controller, Motor Control and Actuator Monitoring, Digital Monitoring Equipment, Low-Cost IoT Control Node, Consumer Equipment Control Panel, Automated Test and Measurement Module.
Compact Industrial Sensor Controller
The STM32G041C8U6 fits compact sensor controllers because its 64 MHz Arm Cortex-M0+ core provides responsive digital control while 64 KB of Flash and 8 KB of RAM accommodate acquisition logic and communications. The 48-pin UFQFPN package supports compact, automated PCB assembly. According to the STMicroelectronics manufacturer datasheet, the STM32G041x6/x8 family is a mainstream Cortex-M0+ platform. Its practical advantage is integrated processing without the memory overhead of a higher-end MCU, although the designer must verify the required analog channels, operating voltage, and temperature range before sensor-node release.
おすすめ
Motor Control and Actuator Monitoring
The STM32G041C8U6 is appropriate for small motor-control and actuator-monitoring modules where deterministic real-time logic is needed but the firmware remains within 64 KB of Flash. Its Cortex-M0+ core operates up to 64 MHz, providing useful timing margin for pulse generation, state-machine control, and fault handling. According to the STMicroelectronics manufacturer materials, the device belongs to the mainstream STM32G0 family. The design must confirm timer, PWM, encoder, and comparator availability from the complete datasheet, because those functional differences determine whether the MCU can replace a larger controller.
おすすめ
Digital Monitoring Equipment
For digital monitoring equipment, the STM32G041C8U6 combines a 64 MHz Cortex-M0+ core with 64 KB of program Flash and 8 KB of SRAM, allowing it to supervise thresholds, debounce inputs, record status, and update a local display. Its 48-pin package leaves multiple I/O options for sensors, communication interfaces, and indicators. According to the STMicroelectronics manufacturer datasheet, the STM32G041x6/x8 devices are mainstream 32-bit RISC MCUs. Select the package variant and validate the pin multiplexing, ADC accuracy, and communication peripherals required by the instrument.
おすすめ
Low-Cost IoT Control Node
The STM32G041C8U6 can serve as the local control processor in a compact IoT node, handling sensor polling, state logic, actuator commands, and low-rate data formatting before a communications module transmits results. Its 64 MHz Cortex-M0+ core offers enough control headroom, while 64 KB of Flash and 8 KB of RAM remain practical for focused embedded firmware. According to the STMicroelectronics manufacturer product page, the part is a mainstream STM32G0 MCU. Power availability and communications are peripheral-specific, so use the device tree and reference manual to confirm radio, interface, and low-power requirements.
おすすめ
Consumer Equipment Control Panel
The STM32G041C8U6 is well suited to consumer equipment control panels that coordinate buttons, indicators, relays, and status displays. Its 32-bit Cortex-M0+ architecture handles responsive UI-state logic, and the 48-pin UFQFPN package enables a small, fully surface-mounted design. According to the STMicroelectronics manufacturer datasheet, the target is part of the mainstream STM32G041x6/x8 family with operation up to 64 MHz. The BOM can remain economical when firmware fits comfortably within 64 KB, but production validation should include brownout behavior, relay-drive timing, and the exact GPIO assignment.
おすすめ
Automated Test and Measurement Module
The STM32G041C8U6 can coordinate automated test modules that sequence fixtures, capture digital results, and communicate status to a host controller. A 64 MHz Cortex-M0+ core provides timely sequencing, while 64 KB of Flash supports a dedicated test application and 8 KB of RAM handles working state. According to the STMicroelectronics manufacturer materials, the STM32G041x6/x8 devices use the Cortex-M0+ 32-bit RISC core. Before deployment, verify analog measurement accuracy, timer resolution, communication interfaces, and operating-temperature limits against the complete manufacturer datasheet.

設計ノート
Use the exact UFQFPN land pattern and exposed-pad geometry defined in the STMicroelectronics package documentation. Place the device-side input and output decoupling capacitors adjacent to their associated supply pins, while preserving a continuous ground reference beneath the package where the recommended layout permits. Treat the exposed pad as both a thermal surface and a ground connection according to the manufacturer drawing. Do not infer exposed-pad connections from another STM32G0 package.
Separate analog and digital return paths where the board architecture permits, and keep high-current switching-node copper away from oscillator, ADC, and reference connections. Route the debug interface and clock signals away from potential sources of switching noise. The manufacturer datasheet notes that VREF+ is internally connected to VDD on packages without a dedicated VREF+ pin and that the internal reference buffer must then be disabled, so firmware and layout assumptions must match the selected package.
Plan the power tree so every STM32G041C8U6 supply rail remains inside the limits listed in the manufacturer datasheet, including tolerance, ripple, startup, and brownout behavior. Verify whether unused supply-related pins require external connection and whether the selected package exposes VREF+ separately. Provide the decoupling network recommended by the manufacturer reference design, then test power sequencing in the final board rather than relying on nominal regulator outputs.
Do not substitute a similarly named STM32G0 device based only on its C8 or U6 package code. The x8 and x6 suffixes can represent different Flash configurations, and related G031, G041, and G061 devices can differ in peripheral availability even when they share a footprint. Before substitution, compare the complete pin descriptions, alternate-function mappings, clock tree, ADC channels, timers, communication interfaces, electrical limits, startup behavior, and package drawing, then run firmware regression tests.
