STM32G041C8T6 - 64MHz Cortex-M0+ 64KB MCU | STMicroelectronics
MPN： STM32G041C8T6 ✓ 啟用中STM32G041C8T6 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile data memory, peripherals, and communication interfaces on one integrated circuit. In the device hierarchy, an MCU is a semiconductor and embedded-control IC; the STM32G0 family combines general-purpose processing with analog and digital peripherals for compact control boards, sensors, actuators, and communication equipment.
The STM32G041C8T6 combines a 64 MHz Cortex-M0+ core with 64 KB Flash and 8 KB RAM. Its 1.7 V to 3.6 V operating supply supports low-voltage embedded systems, while the listed 2 USARTs provide serial connectivity for debugging, module integration, or peripheral communication. The family description specifically associates STM32G041x6/x8 devices with mainstream embedded applications, making this part appropriate for compact control logic where performance and integration matter.
The STM32G0 architecture uses a 32-bit RISC core designed for efficient embedded execution. Flash retains programmed firmware after power removal, while RAM supports working data and execution state. This division allows the MCU to operate as a self-contained controller without requiring external program memory. Exact peripheral inventories, pin multiplexing, clock limits under each voltage range, and performance figures beyond the verified values are not inferred here.
Typical applications include low-voltage sensor nodes, compact motor-control peripherals, industrial control modules, communication bridges, and embedded instruments. Two USARTs can support a host interface and an external module, while the 64 KB Flash capacity provides room for application firmware and boot logic. The 48-LQFP package is appropriate for through-hole assembly and manual prototyping where a fine-pitch BGA would be inconvenient.
Designers should use the manufacturer datasheet for the exact 48-pin map, alternate-function assignments, decoupling requirements, clock configuration, and programming procedure. Because the package is relatively large and exposed to handling and soldering challenges, verify PCB footprint, pin orientation, and assembly capability before committing to a board. Firmware migration should also be reviewed rather than assuming software compatibility from the family name alone.
This page consolidates verified manufacturer and distributor facts, separates verified values from missing parameters, and emphasizes procurement, application, and design context. It does not invent unprovided electrical details, pricing tiers, pin assignments, lifecycle claims, or drop-in alternatives; those items remain explicitly qualified for engineering validation.

典型應用
STM32G041C8T6 適用於 6 應用s: Low-Voltage Sensor Node, Compact Communication Module, Embedded Measurement Instrument, Compact Motor or Actuator Controller, USB-to-Serial Embedded Bridge, Industrial Control Module.
Low-Voltage Sensor Node
The STM32G041C8T6 fits compact sensor-node designs because its Cortex-M0+ core operates up to 64 MHz, while 64 KB Flash and 8 KB RAM provide room for firmware and working data. The 1.7 V to 3.6 V supply range is useful for battery-derived or regulated low-voltage systems. Two listed USARTs can connect a local sensor or radio module and provide a separate service or logging link. Designers should confirm ADC resolution, timer resources, GPIO availability, and the exact pin map in the manufacturer datasheet before finalizing the sensor front end.
推薦
Compact Communication Module
The STM32G041C8T6 is a practical candidate for communication modules because two USARTs are explicitly listed and the 64 MHz Cortex-M0+ core provides additional control headroom. It can manage protocol framing, configuration, status reporting, and local supervision around a wireless or serial transceiver. The 48-LQFP package supports a straightforward external-component layout, although the exact alternate-function routing and peripheral electrical limits must be checked. Firmware partitioning and protocol timing should be validated against the final transceiver and power architecture.
推薦
Embedded Measurement Instrument
The STM32G041C8T6 can serve as the control core in a compact measurement instrument when the design needs local acquisition control, calibration storage, and a serial service interface. Its 64 KB Flash supports embedded firmware and configuration code, while 8 KB RAM is suitable for modest control tasks. The 1.7 V to 3.6 V range simplifies integration with low-voltage analog and digital rails. Before selecting it, verify ADC characteristics, timer accuracy, reference voltage behavior, calibration storage strategy, and whether 8 KB RAM is sufficient for the chosen signal-processing workload.
推薦
Compact Motor or Actuator Controller
The STM32G041C8T6 may be suitable for small actuator-control boards because it combines a 64 MHz Cortex-M0+ core, two USARTs, and a low-voltage operating range in a 48-LQFP package. A practical design could use the MCU for command parsing, position or timing logic, sensor monitoring, and fault-state reporting, while external drivers handle power switching. The verified data does not establish dedicated motor-control peripherals, PWM channels, ADC performance, or protection limits, so those functions must be confirmed before use in any high-current or safety-related system.
推薦
USB-to-Serial Embedded Bridge
The STM32G041C8T6 can be evaluated as the protocol controller in an embedded USB-to-serial bridge when two USART resources are useful for separating a host-side link from a target-side link. Its 64 KB Flash and 8 KB RAM are adequate for firmware involving USB handling, serial buffering, configuration, and status reporting, subject to the selected USB interface and protocol stack. The 48-LQFP package offers a usable prototyping footprint, but USB electrical compliance, transceiver requirements, firmware support, and exact peripheral availability are not established by the supplied data.
推薦
Industrial Control Module
The STM32G041C8T6 is a candidate for small industrial control modules where local logic, serial device management, and compact firmware storage are needed. Its Cortex-M0+ core operates up to 64 MHz, and the 1.7 V to 3.6 V supply range can simplify integration into low-voltage regulated equipment. Two USARTs may support a controller bus and service port. Industrial deployment still requires verification of the operating-temperature range, EMC behavior, ESD tolerance, isolation strategy, watchdog requirements, and long-term availability; those specifications were not included in the verified data.

設計說明
Use the exact STMicroelectronics 48-LQFP footprint and verify pin-1 orientation against the package drawing before layout release. The verified package is 48-LQFP, 7 x 7 mm, but the supplied data does not provide the pin-by-pin electrical map or exposed-pad details. Confirm the land pattern, solder mask, paste stencil, and assembly clearance with the manufacturer package documentation.
Design the supply rail for the verified 1.7 V to 3.6 V STM32G041C8T6 operating range, with regulator headroom for startup and load transients. Place the required bypass capacitors close to the device supply pins according to the datasheet layout guidance, and check the external regulator’s noise and settling behavior against the firmware’s timing assumptions. Current consumption and decoupling values were not supplied and must be verified directly from STMicroelectronics documentation.
Do not assume that a similarly named STM32G041 device is a drop-in replacement. Compare the complete ordering code, memory density, temperature grade, package, pin multiplexing, peripheral availability, clock settings, and firmware startup assumptions. In particular, the verified data does not establish pin compatibility, lifecycle equivalence, or electrical equivalence for any substitute, so a cross-reference must be validated before PCB or firmware reuse.
For serial links, define the logic levels and transceiver strategy before assigning the two USARTs to connectors or modules. The verified results establish two USART interfaces but do not specify their alternate-function pins, electrical characteristics, or supported protocols. Review the datasheet pin table, select the intended alternate functions, keep return paths short, and validate signal integrity with the actual cable, connector, baud rate, and grounding arrangement.
合規資訊
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is listed as not_applicable only because no automotive qualification claim is provided for this exact orderable MPN; verify quality-grade documentation before industrial or automotive use.
