STM32G473CEU6 - 170MHz Cortex-M4 512KB MCU | STMicroelectronics
부품 번호: STM32G473CEU6 ✓ 활성STM32G473CEU6 개요
An Arm Cortex-M4 microcontroller is a 32-bit reduced-instruction-computing core within the broader embedded processor and microcontroller hierarchy. It combines interrupt-driven control, compact embedded software, and integrated peripherals on one package. Compared with a general-purpose processor, an MCU is optimized for responsive real-time control, while the STM32G4 series adds enhanced analog resources and math-acceleration hardware for control-oriented designs.
The STM32G473CEU6 combines three headline attributes: a maximum clock frequency of 170 MHz, 512 KB of programmable Flash, and a 48-UFQFPN package with a 7 mm by 7 mm footprint. The 512 KB Flash provides substantially more room for application code, libraries, configuration data, and update logic than the entry-level variants of the family. Its compact UFQFPN package also supports space-constrained control boards while exposing a high pin count for analog, communications, and control connections.
The STM32G473xB, STM32G473xC, and STM32G473xE devices use the high-performance 32-bit Arm Cortex-M4 RISC core, according to the STMicroelectronics product page. Distributor records additionally identify the STM32G473CEU6 as a mainstream MCU with math-acceleration and high-analog features. These characteristics distinguish it from simpler Cortex-M0 or Cortex-M3 devices when a design benefits from faster numeric execution, more Flash storage, and a broader collection of analog peripherals.
Typical applications include industrial motor controllers, digital power supplies, industrial automation modules, sensor-conditioning systems, communications equipment, and embedded measurement platforms. The combination of 170 MHz processing, 512 KB Flash, math acceleration, and enhanced analog capability is particularly useful where control algorithms must run alongside high-speed sampling, monitoring, and communications. Engineers should still verify individual peripheral assignments, analog performance, and pin multiplexing against the official STM32G473CE datasheet.
For PCB implementation, use the manufacturer's 48-pin UFQFPN land pattern, exposed-pad thermal design, and recommended decoupling arrangement. Validate the PCB stack-up and thermal path before production because the 7 mm by 7 mm package concentrates heat around its exposed pad. Firmware, peripheral configuration, clock planning, and pin assignment should follow STMicroelectronics documentation for the STM32G473xB/xC/xE family.
This page consolidates verified distributor specifications, the official product-page information, strict same-package alternatives, and practical selection guidance. It distinguishes documented facts from parameters that still require confirmation, providing a more useful engineering reference than a distributor title or generic cross-reference listing alone.

Industrial Motor Control
The STM32G473CEU6 fits industrial motor-control platforms that require real-time computation, substantial firmware storage, and mixed analog and digital signal processing. Its 170 MHz Arm Cortex-M4 core provides headroom for current-control loops, fault handling, digital filters, and communications tasks, while 512 KB of Flash can hold control algorithms and field-update logic. The high-analog capability identified by Mouser is useful when the controller must monitor motor voltage, current, and temperature. A typical implementation uses the MCU beside gate drivers, position sensors, and protection circuitry. The verified excerpts do not enumerate the exact timer outputs, ADC specifications, or PWM channels, so those functions must be confirmed in the manufacturer pinout and peripheral tables before schematic assignment.
추천
Digital Power Conversion
STM32G473CEU6 is suitable for digital power-conversion controllers that combine fast control computation with analog feedback and firmware-based regulation. The 170 MHz Cortex-M4 core can execute compensation algorithms and supervisory logic, while the documented math-acceleration feature can accelerate suitable arithmetic workloads. Its 512 KB Flash provides room for compensation tables, communications protocols, calibration data, and event logging. The high-analog feature set is valuable when sensing feedback signals directly within the MCU. A practical design would connect the MCU to power-stage sensing and gate-drive circuitry while using its digital control outputs for regulation. Exact converter timers, DAC functions, comparators, and analog accuracy are not included in the verified excerpts and must be checked against the STM32G473CE datasheet.
추천
Industrial Automation and Condition Monitoring
The STM32G473CEU6 can serve as the central controller in industrial automation and condition-monitoring equipment where a compact package, fast core, and generous Flash simplify a multi-function design. At 170 MHz, the Cortex-M4 MCU can process acquisition data, filter sensor information, manage local logic, and support communication updates. The 512 KB Flash capacity allows embedded analytics and protocol stacks to coexist without relying on external program memory. Its high-analog capability is especially relevant for equipment that monitors transducers or supply rails. Designers should plan decoupling, exposed-pad grounding, and analog layout around the official 48-UFQFPN drawing. Because the verified records do not specify the ADC resolution, timer resources, or operating voltage, those details require direct manufacturer-document confirmation.
추천
Communications and Networked Embedded Modules
STM32G473CEU6 is appropriate for compact communications modules that need more compute and program storage than entry-level Cortex-M devices. The 170 MHz Arm Cortex-M4 core supports protocol processing, packet handling, and multitasking, while 512 KB of Flash can hold network stacks, application firmware, and secure configuration data. The 7 mm by 7 mm 48-pin UFQFPN package helps reduce board size while retaining a comparatively high pin count for communications and status interfaces. The MCU can also service concurrent measurement and control tasks because of its mainline performance and analog capabilities. Specific Ethernet or USB support, peripheral sharing, and pin assignments were not included in the verified excerpts, so the manufacturer datasheet must be consulted before selecting it for a particular network standard.
추천
Precision Measurement and Sensor Interface
STM32G473CEU6 fits precision measurement modules that combine sensor acquisition, digital filtering, calibration, and data formatting in one microcontroller. Its 170 MHz Cortex-M4 core can process measurement sequences and compensation algorithms, while the advertised high-analog capabilities make the family appropriate for signal-chain-adjacent functions. With 512 KB of Flash, the device can retain instrument firmware, calibration coefficients, lookup tables, and communication routines. The compact 48-pin UFQFPN footprint supports portable or embedded instrument designs without requiring a larger plastic package. Designers should use the official exposed-pad and analog-layout guidance, keep sensitive inputs away from fast-switching nodes, and verify ADC resolution, reference accuracy, sampling characteristics, and available analog channels in the manufacturer documentation.
추천
Embedded Audio and Signal Processing
STM32G473CEU6 can support embedded audio or general signal-processing functions where real-time execution and local storage are more important than a low-cost minimal MCU. The 170 MHz Cortex-M4 core provides the instruction throughput required for filters, mixing, modulation, or control loops, while math-acceleration hardware can improve selected numerical workloads. Its 512 KB Flash accommodates firmware, sound tables, configuration, and update logic. The high-analog feature set may assist with input conditioning and monitoring, although the verified excerpts do not confirm audio-specific converters or interfaces. A practical implementation would separate sensitive analog paths from digital activity and use the manufacturer's recommended decoupling and exposed-pad layout. ADC, DAC, timer, clock, and pin-function details must be verified directly before schematic sign-off.

설계 노트
Create the PCB footprint from STMicroelectronics' official 48-UFQFPN package drawing rather than from a generic 48-pin QFN footprint. The verified distributor excerpt confirms the 7 mm by 7 mm body but does not provide the exposed-pad dimensions, lead pitch, or solder-mask details. Verify those dimensions, pin-1 orientation, courtyard, and paste-aperture geometry before releasing the PCB library footprint.
Treat the exposed pad as both an electrical connection and a thermal path. Use the manufacturer's recommended via pattern and connect the pad to the appropriate ground plane unless the selected pin assignment specifies otherwise. Estimate junction temperature using the actual flash activity, clock loading, ambient temperature, and board copper rather than treating the 7 mm by 7 mm package size as proof of adequate cooling.
Separate analog-sensitive routing from high-speed digital and switching nodes, following the official STM32G473CE pin-muxing and analog-layout guidance. Place required decoupling capacitors close to their associated supply pins with short ground returns, and keep exposed-pad vias low impedance. Because the verified excerpts do not identify the complete analog pin set or reference configuration, validate every selected analog connection against the manufacturer pinout.
Do not substitute a same-family ordering suffix without reviewing the manufacturer ordering information. Although STM32G473CEU3, STM32G473CEU3TR, and STM32G473CEU6F appear in the verified cross-reference results, suffix-specific temperature limits, qualification, tape-and-reel format, and product-status conditions are not exposed. Confirm those details and the exact exposed-pad pinout before approving a drop-in substitution.
규정 준수 정보
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because no automotive qualification claim appears in the verified data; this does not exclude a separately qualified suffix.
