STM32G031C4U6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
부품 번호: STM32G031C4U6 ✓ 활성STM32G031C4U6 개요
A microcontroller is a programmable semiconductor that integrates a CPU core, program memory, data memory, and peripherals such as analog-to-digital converters, timers, communication interfaces, and GPIO into one package. The STM32G031 belongs to the STM32G0 family and the ARM Cortex-M0+ hierarchy, where the simplified Cortex-M0+ core is designed for efficient, low-cost real-time control. In system terms, it is a microcontroller MCU and embedded-control IC rather than a general-purpose processor.
The verified configuration emphasizes a practical balance of processing speed, memory, and analog capability. Its maximum CPU frequency is 64 MHz, its Flash organization is 16K x 8, and its SRAM capacity is 8 KB. The device includes a 12-bit ADC according to the distributor data. Its 1.7 V minimum operating voltage permits use in low-voltage equipment, while the 3.6 V maximum supports conventional 3.3 V systems when appropriate decoupling and voltage regulation are applied.
The STM32G031C4U6 combines a single Cortex-M0+ processing core with 16 KB of Flash and 8 KB of SRAM. Its 48-UFQFPN exposed-pad package supports compact PCB layouts, but the exposed pad must be connected to the ground plane as specified by the manufacturer. The 12-bit ADC is useful for reading potentiometers, sensors, and other analog inputs, while GPIO and embedded-control functions support common industrial-control tasks.
Typical uses include compact sensor controllers, analog monitoring modules, low-power monitoring equipment, basic serial-interface control systems, and small industrial automation nodes. Designers should use the STM32G0 ecosystem for peripheral configuration and firmware development. Because the available verified data does not enumerate every peripheral, timer, communication interface, pin, or ADC channel, those details should be confirmed in the official STM32G031 documentation before final schematic and firmware decisions.
The main design consideration is to preserve signal and power integrity around the exposed-pad device. Place the decoupling capacitors close to their associated supply pins, provide an uninterrupted ground connection beneath the exposed pad, and route high-current or switching signals away from sensitive analog inputs. Confirm the exact pin multiplexing and alternate-function assignments in the official datasheet because the supplied search data confirms the 48-pin package but not the complete pinout.
This page consolidates the verified distributor specifications, sourcing information, application guidance, and verified availability context into a design-focused reference. It also clearly separates confirmed facts from parameters that still require the manufacturer datasheet, helping engineers evaluate the STM32G031C4U6 without assuming unverified pin, peripheral, lifecycle, or compliance details.

일반적인 애플리케이션

Compact Industrial Sensor Controller
The STM32G031C4U6 fits compact industrial sensor controllers because it combines a 64 MHz ARM Cortex-M0+ core, 16 KB of Flash, and 8 KB of SRAM in a compact 48-pin UFQFPN package. Its 12-bit ADC can process analog sensor signals, while the Cortex-M0+ core can handle configuration, filtering, and control functions. The 1.7 V to 3.6 V operating range permits integration into low-voltage industrial nodes, provided the power source remains within the specified limits. A key consideration is firmware size: the 16 KB Flash capacity leaves little margin for complex stacks or extensive logging, so application code should be measured during development.
추천
Low-Voltage Analog Monitoring Module
The STM32G031C4U6 is appropriate for a low-voltage analog monitoring module because its 12-bit ADC, 64 MHz processing core, and 1.7 V to 3.6 V operating range support compact measurement systems. It can sample analog inputs, apply digital filtering, and report measurements through an available MCU interface. The 8 KB of SRAM is suitable for bounded sample buffers and control state, while 16 KB of Flash limits the complexity of local storage and application logic. Place decoupling capacitors close to the supply pins and keep the analog trace away from fast-switching nodes to preserve measurement quality.
추천
Basic Motor and Actuator Control
The STM32G031C4U6 can serve as the supervisory controller in a basic motor or actuator system, using its GPIO and embedded-control functions to sequence commands and monitor feedback. The 64 MHz Cortex-M0+ core provides responsive real-time execution, while the 48-pin UFQFPN package limits board size in space-constrained equipment. Its 8 KB of SRAM and 16 KB of Flash are adequate for compact control loops but not extensive motion-planning data. External driver circuits, protection components, and filtering are still required; verify the exact timer and pin assignments in the manufacturer documentation.
추천
Portable Measurement and Diagnostic Device
The STM32G031C4U6 fits portable measurement and diagnostic equipment requiring low voltage, modest memory, and analog acquisition in a small package. Its 3.3 V-compatible operating point and 1.7 V lower limit support battery-managed designs, while the 12-bit ADC supports sensor-conditioned measurements. The device can execute calibration logic, threshold checks, and user-interface updates, but its 16 KB Flash capacity may constrain large feature sets. Low-power behavior, battery load current, and sleep-mode performance are not confirmed in the supplied data and must be evaluated from official documentation.
추천
Networked Sensor Node
The STM32G031C4U6 can act as the local control MCU in a networked sensor node when the communications interface has been confirmed for the specific ordering code. Its 64 MHz core is sufficient for packet preparation, sensor management, and local filtering, while 8 KB of SRAM can support bounded network buffers. The compact 48-pin UFQFPN package is useful in space-constrained gateways. Communication peripheral details are not present in the verified search data, so engineers must check the official datasheet and selected transceiver before committing to this component.
추천
Human-Machine Control Interface
The STM32G031C4U6 is suitable for a small human-machine control interface that combines button or encoder input, indicator control, and analog adjustment. Its GPIO resources and 64 MHz core can support responsive interaction logic, while the 12-bit ADC can read a control potentiometer or analog input. The 48-pin package allows a compact controller layout, and the 16 KB Flash is generally suitable for a focused interface when a heavier graphics framework is not required. Exact I/O counts, timer channels, and pin alternate functions must be verified from the manufacturer documentation.

설계 노트
Use the official STMicroelectronics 48-pin UFQFPN land pattern and verify the exposed-pad dimensions and thermal-via recommendations against the package drawing. Place the device-side decoupling capacitors as close as practical to the associated supply pins, with a short ground return path. The exposed pad should connect to the ground plane using the recommended via arrangement rather than an improvised thermal pattern.
Separate analog inputs from switching nodes and high-current return paths to reduce conversion error in the 12-bit ADC. Keep sensor traces short, use a continuous reference ground, and avoid routing sensitive inputs beneath digital clock or switching nets. Because the supplied data does not identify ADC pins or alternate functions, use the official pinout and analog recommendations when assigning the sensitive signals.
Do not treat the listed $1.1796 price as a firm quotation for every volume, nor assume that a related STM32G0 order code is a drop-in substitute. The verified source provides a starting price and limited cross-reference information but no complete pinout, peripheral matrix, lifecycle detail, or approved equivalent list. Validate memory usage, exact peripheral requirements, package compatibility, and current distributor stock before layout release.
규정 준수 정보
The supplied verified search results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the product family.
