STM32G051C8U6 - 64MHz Arm Cortex-M0+ MCU | STMicroelectronics
N.º da peça: STM32G051C8U6 ✓ AtivoSTM32G051C8U6 Visão geral
An Arm Cortex-M0+ microcontroller is a 32-bit reduced-instruction-set processor designed for cost-sensitive embedded systems. It belongs to the microcontroller hierarchy within semiconductor devices and combines a CPU, memory, analog peripherals, communication interfaces, timers, and GPIO in one package. The STM32G0 family emphasizes efficient control operation, compact implementation, and broad peripheral integration for industrial, consumer, and communications equipment.
The STM32G051C8U6 reaches up to 64 MHz and includes 64 KB of protected Flash together with 18 KB of SRAM. According to the verified product information, 16 KB of the SRAM has hardware parity checking. Two USART channels support serial equipment, while the listed timers, ADC, DAC, and communication interfaces reduce the need for external components in measurement, control, and communications-oriented products.
Its 1.7 V to 3.6 V operating range permits use in systems powered from low-voltage rails. The available temperature ratings shown in the verified data span -40°C through 85°C, 105°C, or 125°C, depending on the device variant. The 48-pin UFQFPN package provides a compact 7 x 7 mm footprint and includes 45 I/O according to the Octopart comparison data, making the MCU suitable for boards where connector density and routing space are important.
Typical applications include compact sensor-control modules, industrial monitoring equipment, consumer controls, communication transceivers, low-power embedded nodes, and general-purpose control boards. The Cortex-M0+ platform and integrated analog and serial peripherals allow designers to consolidate functions that might otherwise require several discrete components.
When designing around the STM32G051C8U6, verify every signal against the exact 48-pin package variant and provide the decoupling and grounding required by the manufacturer guidance. Software migration between similarly named STM32G0 devices should be treated as a new-device qualification rather than assumed to be automatic, because memory size and peripheral availability can differ.
This page combines verified manufacturer and distributor specifications, strict same-package drop-in candidates, practical application guidance, and a parameter-by-parameter comparison to support faster engineering and sourcing decisions beyond the basic distributor listing.

Aplicações típicas
STM32G051C8U6 é adequado para 6 aplicaçãos: Compact Sensor-Control Module, Industrial Monitoring Equipment, Serial Communication Gateway, Consumer Control Panel, Low-Power Embedded Node, Connected Equipment Controller.
Compact Sensor-Control Module
The STM32G051C8U6 fits compact sensor-control modules because its 64 MHz Arm Cortex-M0+ core provides responsive control processing while the 64 KB Flash and 18 KB SRAM support protocol handling and local data buffering. The integrated ADC, timers, and communication interfaces can reduce the number of external components in a measurement node. Its 1.7 V to 3.6 V operating range also supports low-voltage sensor architectures. The 48-pin UFQFPN package reduces board area, although the exposed-pad layout and thermal path must be implemented exactly as specified by the manufacturer.
Recomendado
Industrial Monitoring Equipment
For industrial monitoring equipment, the STM32G051C8U6 combines a 64 MHz 32-bit core, 45 I/O, two USART channels, timers, ADC, and DAC within a compact 48-pin package. These resources suit sensing, threshold evaluation, actuator control, data logging, and local diagnostics. The 1.7 V to 3.6 V supply range simplifies integration with regulated industrial rails. Qualification for an industrial system still requires selection of the correct temperature grade, validation of EMC and surge requirements, and use of isolation or protection interfaces for externally connected wiring.
Recomendado
Serial Communication Gateway
The STM32G051C8U6 is appropriate for compact serial gateways because it provides two USART channels, an ADC, timers, and communication interfaces in a 48-pin UFQFPN package. A design can use one USART for a local host and another for a field-side transceiver while the MCU performs protocol conversion, filtering, and status reporting. Its 64 MHz processing rate and 18 KB SRAM provide adequate capacity for lightweight gateway functions. Engineers should verify the exact USART feature set and pin multiplexing for the selected ordering code before final board routing.
Recomendado
Consumer Control Panel
The STM32G051C8U6 can implement a cost-conscious consumer control panel with local button handling, LED indication, sensor updates, and serial configuration. Its 45 I/O provide substantial control connectivity despite the compact 48-pin package, while the ADC supports analog inputs and the timers support periodic background tasks. The 1.7 V to 3.6 V range supports common low-voltage power systems. Firmware size, display requirements, standby behavior, and production test coverage should be evaluated against the available 64 KB Flash and 18 KB SRAM.
Recomendado
Low-Power Embedded Node
The STM32G051C8U6 is suitable for low-power embedded nodes that periodically acquire data, process it locally, and transmit it through a serial interface. Its Cortex-M0+ architecture operates up to 64 MHz for responsive control, while the available timers support periodic wake-up and sampling tasks. The 64 KB Flash accommodates small protocol and application firmware, and the 18 KB SRAM allows transient data handling without an external memory device. Exact low-power current, wake-up timing, and peripheral availability must be checked in the manufacturer documentation because those values were not included in the retrieved excerpts.
Recomendado
Connected Equipment Controller
The STM32G051C8U6 can serve as the local controller in connected equipment that combines user controls, analog measurement, and wired communication. Its 64 MHz Cortex-M0+ core handles protocol tasks and control logic, while two USART channels and the listed communication interfaces support multi-port designs. The 48-pin UFQFPN footprint preserves board space, and the 1.7 V to 3.6 V range permits operation from a regulated low-voltage rail. Board designers should reserve clean grounding and careful decoupling for the MCU while selecting external transceivers according to the required communication standard.

Notas de projeto
Route the 48-pin UFQFPN footprint exactly to the STMicroelectronics land pattern and confirm whether the exposed pad is connected to ground, power, or left according to the selected device variant. Place required bypass capacitors close to their associated supply pins and preserve short return paths. The verified excerpts provide the 7 x 7 mm package dimensions but not the complete land pattern, so board libraries should be checked against the current manufacturer footprint rather than reconstructed from package size alone.
Design the supply rail for the verified 1.7 V to 3.6 V operating range and account for startup, dynamic current, peripheral load, and voltage tolerance across the complete product temperature range. Decoupling requirements, internal regulator behavior, and maximum external clock conditions must be taken from the manufacturer datasheet for the exact ordering code. Do not infer absolute maximum ratings or power consumption from the distributor summary because those values were not present in the supplied data.
Treat same-package STM32G0 candidates as qualified replacements only after checking the complete pinout, alternate-function mapping, clock tree, ADC channels, timers, communication peripherals, bootloader behavior, and Flash/RAM requirements. The STM32G051C6U6 is a clear memory-capacity tradeoff at 32 KB versus 64 KB, while other related devices may differ in USB, security, or analog features. Package compatibility alone does not guarantee binary firmware compatibility.
Keep analog and communication signals away from noisy switching nodes, provide a continuous ground reference beneath the MCU where the footprint permits, and use the package exposed pad as part of the thermal and return-current strategy. For designs using the ADC, DAC, or USART interfaces, route sensitive signals away from high-current edges and provide clean local references. The retrieved data confirms the interfaces exist but does not provide complete recommended-layout or decoupling values, so those must be taken from STMicroelectronics guidance.
Informações de conformidade
The verified excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for STM32G051C8U6. Compliance must be checked against the current manufacturer documentation for the exact ordering code.
