STM32G051K8U6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
부품 번호: STM32G051K8U6 ✓ 활성STM32G051K8U6 개요
A microcontroller is an integrated circuit that combines a processor core, nonvolatile program memory, volatile data memory, and peripherals on one semiconductor device. Within the embedded-system hierarchy, the STM32G051 belongs to the Arm Cortex-M0+ microcontroller family and the STM32G0 series. Its low-power architecture supports cost-sensitive industrial, consumer, and communication-oriented products where modest processing performance and compactness are more important than a high-end application processor.
The STM32G051x6/x8 device family combines up to 64 KB of Flash, 18 KB of SRAM, and a maximum Cortex-M0+ clock frequency of 64 MHz. The verified product information identifies two USART interfaces, timers, ADC, DAC, and communication interfaces. Flash protection and a securable area support controlled firmware deployment, while 16 KB of the SRAM is specified with hardware parity checking for improved data-integrity behavior.
The STM32G051K8U6 is packaged in a compact 32-pin UFQFPN, making it appropriate for space-constrained boards requiring mixed-signal control and serial communications. Its 1.7 V to 3.6 V operating range allows use in 3.3 V systems and designs with adjusted supply rails. The exact maximum and minimum external clock, GPIO count, ADC resolution, DAC format, timer channels, and package dimensions beyond the verified 5 x 5 mm size are not specified in the supplied web data and should be confirmed in the manufacturer documentation before schematic release.
Typical uses include small sensor-control boards, industrial interface modules, consumer appliances, communications equipment, and compact motor or power-control subsystems. The two USARTs support serial links, while the ADC and DAC enable analog measurement and signal generation without requiring separate converters. Engineers should preserve the detailed peripheral mapping and alternate-function requirements of the exact UFQFPN land pattern during PCB design.
A practical design consideration is the relationship between the 1.7 V minimum operating voltage and the selected external components. Signal-generating and signal-consuming devices sharing the MCU supply must use rail-compatible logic levels, and the decoupling strategy should follow the manufacturer recommendations for the selected package. Firmware, peripheral errata, and package-specific pin assignments should also be checked against the final device revision.
This page consolidates manufacturer product information, distributor listing details, procurement data, strict drop-in replacement screening, and engineering-oriented design guidance. It distinguishes verified specifications from unavailable parameters rather than inferring missing electrical or timing values, helping engineers evaluate the STM32G051K8U6 before committing a PCB footprint or production BOM.

일반적인 애플리케이션
STM32G051K8U6 적합 용도: 6 애플리케이션s: Compact Sensor-Control Node, Industrial Serial Interface Module, Consumer Appliance Controller, Communications Auxiliary Controller, Analog Signal Conditioning Controller, Compact Motor or Power-Control Subsystem.
Compact Sensor-Control Node
The STM32G051K8U6 fits compact sensor-control nodes because its 64 MHz Arm Cortex-M0+ core can handle local acquisition, filtering, and control logic while 64 KB of Flash holds application firmware. The integrated ADC reduces the need for a separate analog-to-digital converter, and the two USARTs support sensor or service links. Its 32-pin UFQFPN occupies only 5 x 5 mm, leaving board area for power conversion and sensors. The principal design trade-off is limited memory: 18 KB of SRAM requires careful buffer allocation, and the exact pin assignments and peripheral channels must be confirmed against the package documentation before layout.
추천
Industrial Serial Interface Module
The two USARTs and 64 MHz Cortex-M0+ processing capability make the STM32G051K8U6 suitable for small industrial interface modules that bridge sensors, actuators, or legacy serial equipment. Its 1.7 V to 3.6 V operating range supports compact 3.3 V system architectures, while integrated timers support periodic measurement, timeout, and communication tasks. The 32-pin 5 x 5 mm UFQFPN leaves room for connectors, surge protection, and a regulated supply. Designers should verify baud-rate tolerance, peripheral instance availability, and the exact serial-pin alternate functions because those details are not included in the supplied listing excerpts.
추천
Consumer Appliance Controller
The STM32G051K8U6 can serve as the primary controller in a compact consumer appliance where the control loop is modest but reliable peripheral integration is valuable. Its 64 KB of protected Flash supports product firmware, the 18 KB of SRAM accommodates control state, and the ADC can monitor analog inputs. The DAC can generate a reference or control waveform when the application requires it. The 32-pin UFQFPN supports dense layouts, although developers must budget decoupling capacitors, programming access, boot-control circuitry, and connector clearance. Temperature-grade and EMC requirements should be validated for the specific appliance environment before production.
추천
Communications Auxiliary Controller
The STM32G051K8U6 is appropriate for an auxiliary communications controller handling framing, configuration, status reporting, and protocol supervision around a higher-level communications processor. Its two USARTs can support multiple serial links, while timers and 64 MHz execution speed provide deterministic protocol timing. With 64 KB of Flash and 18 KB of SRAM, it is best suited to bounded protocol stacks rather than memory-heavy gateways. The compact 5 x 5 mm UFQFPN helps minimize module area. Firmware must use the exact peripheral mapping and account for communication-line transceivers, isolation, and termination outside the MCU.
추천
Analog Signal Conditioning Controller
The integrated ADC and DAC allow the STM32G051K8U6 to manage basic analog measurement and output functions in a mixed-signal control design. At up to 64 MHz, the Cortex-M0+ core can execute sampling, calibration, and control algorithms while timers organize periodic events. The 1.7 V to 3.6 V range can simplify integration with 3.3 V analog circuitry, provided the MCU supply and reference arrangement meet the device requirements. Exact resolution, sampling rate, accuracy, DAC format, and analog-pin availability are absent from the supplied data and must be verified before selecting this device for precision analog performance.
추천
Compact Motor or Power-Control Subsystem
The STM32G051K8U6 can supervise compact motor- or power-control subsystems when the required actuator interface is handled by external drivers and the MCU handles sequencing, monitoring, and fault logic. Its timers support periodic control tasks, the ADC can observe analog feedback, and the 32-pin UFQFPN helps reduce controller size. The 18 KB SRAM and 64 KB Flash are sufficient for many supervisory tasks, but exact timer channels, comparator resources, PWM outputs, and pin multiplexing are not provided in the supplied excerpts. Engineers should verify the full peripheral set and use manufacturer guidance for safety-critical shutdown paths.

설계 노트
Do not release the UFQFPN footprint until the complete 32-pin table and exposed-pad treatment have been checked against the manufacturer package drawing. The supplied data confirms a 32-pin UFQFPN measuring 5 x 5 mm but does not identify each signal or the exposed pad's electrical connection. Check pin 1 orientation, exposed-pad dimensions, solder-mask clearance, paste apertures, and whether the thermal pad connects to VSS or VDD. These package-specific details are more important than footprint-name similarity because an incorrect pad definition can prevent assembly.
Plan the 1.7 V to 3.6 V supply range into the power architecture rather than treating the MCU rail as always available at 3.3 V. Place the required local decoupling capacitors close to the device's supply and ground pins, with a compact ground return that avoids switching-current loops. The supplied excerpts do not specify the exact decoupling value or internal regulator topology, so engineers should follow the STM32G051x6/x8 hardware guidelines for capacitor selection. Also verify every external interface's logic-level tolerance when the MCU rail is operated below 3.3 V.
Do not infer a drop-in replacement from the STM32G0 family name alone. The verified cross-reference material identifies STM32G051K8U7 as an equivalent candidate, but package identity does not resolve the meaning of the final orderable suffix. Compare the device marking, temperature range, pin table, clock limits, ADC and DAC behavior, Flash and SRAM organization, peripheral instances, boot configuration, errata, and qualification status. Firmware should be retested even when the footprint matches because changes in peripherals or silicon behavior can alter timing and register-level compatibility.
규정 준수 정보
The supplied verified excerpts identify Flash protection, a securable area, and supported operating-temperature grades, but they do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
