STM32G473CET6 - 170MHz Cortex-M4 MCU | STMicroelectronics
料号： STM32G473CET6 ✓ 量产中STM32G473CET6 概述
A microcontroller is a programmable integrated circuit containing a processor core, nonvolatile program memory, volatile data memory, and peripherals such as timers, communication interfaces, and analog converters. In the STM32 hierarchy, the STM32G4 series belongs to the Arm Cortex-M4 MCU class and targets applications requiring more processing performance and analog capability than entry-level Cortex-M devices.
The STM32G473CET6 reaches 170 MHz and provides 512 KB of Flash for firmware storage. Its Cortex-M4 core includes floating-point capability, while the advertised math accelerator supports computationally intensive control and signal-processing workloads. The 48-LQFP 7 x 7 mm package provides a fine-pitch surface-mount option for designs that need many I/O pins without moving to a very large leadless package.
The STM32G4 family is positioned for power electronics, industrial automation, motor control, and embedded analog systems. At 170 MHz, the processor provides substantially greater application-processing headroom than many general-purpose Cortex-M microcontrollers operating below 100 MHz. The combination of 512 KB Flash, math acceleration, and high-performance analog features allows control algorithms, communications protocols, and supervisory logic to coexist in one device.
Typical uses include digital power conversion, motor-control modules, factory automation controllers, data-acquisition systems, communications equipment, and compact embedded control products. The 48-pin package is particularly useful where a board design needs both analog measurement and digital control interfaces while retaining a conventional leaded SMT footprint.
Design planning should begin with the manufacturer's pinout, electrical characteristics, and package drawings because the supplied search data does not expose the complete pin names or absolute timing limits. Designers should also validate peripheral assignments, analog reference requirements, clock-tree configuration, decoupling requirements, and PCB clearances against the official STM32G473CE documentation before release to production.
This page combines the verified 170 MHz, 512 KB Flash, Cortex-M4, and LQFP-48 attributes with package-conscious alternatives, procurement guidance, comparison parameters, and practical application analysis. It distinguishes verified product facts from parameters that require confirmation from the complete manufacturer documentation.

典型应用
STM32G473CET6 适用于 6 应用s: Digital Power Conversion, Industrial Motor Control, Industrial Automation Controller, Precision Data Acquisition, Communications Gateway, Embedded Control and Monitoring.
Digital Power Conversion
The STM32G473CET6 fits digital power-conversion control where a 170 MHz Arm Cortex-M4 core, math acceleration, and high-performance analog capability can improve control-loop responsiveness. Its 512 KB of Flash provides room for compensation algorithms, supervisory logic, communications, and fault handling within one 48-LQFP 7 x 7 mm device. The MCU can execute control calculations while its analog and timer resources manage feedback and power-stage timing. The primary design trade-off is that the available CPU and Flash headroom do not eliminate the need to verify PWM resolution, converter-current capability, thermal margins, and timing against the manufacturer electrical data.
推荐
Industrial Motor Control
The STM32G473CET6 is suitable for compact motor-control modules requiring more computation than a basic 8-bit controller while retaining a 48-pin surface-mount footprint. Its 170 MHz Cortex-M4F processor supports filtering, state estimation, and supervisory functions, and the advertised math accelerator assists control-oriented calculations. The 512 KB Flash capacity can accommodate parameter tables, tuning data, and field-upgrade logic. For servo, BLDC, or stepper applications, engineers must still confirm timer outputs, encoder interfaces, ADC performance, current-sense bandwidth, and motor-control library support in the official documentation.
推荐
Industrial Automation Controller
The STM32G473CET6 can serve as the central controller in a compact factory automation module because it combines 32-bit processing at 170 MHz, 512 KB of embedded Flash, and a broad STM32G4-oriented analog feature set. These resources allow a single MCU to coordinate sensors, actuator logic, communications, and real-time supervisory functions without relying on several low-performance controllers. The LQFP-48 package exposes more pins than a small leadless package while retaining a 7 x 7 mm footprint. Industrial adoption still requires verification of supported field buses, isolated communication limits, operating grade, EMC expectations, and safety requirements.
推荐
Precision Data Acquisition
The STM32G473CET6 is appropriate for embedded measurement systems that need a fast 32-bit control and data-processing path alongside high-performance analog resources. A 170 MHz Cortex-M4F core can process sampled data, apply filtering, run calibration, and format results for a host interface, while 512 KB of Flash holds application code and calibration data. Its 48-LQFP package provides a practical route to external analog, digital I/O, and communications connectivity. The application must be validated against the actual ADC resolution, sampling bandwidth, input impedance, reference stability, and acquisition timing rather than inferred from the 170 MHz CPU frequency.
推荐
Communications Gateway
The STM32G473CET6 can form the processing core of a compact communications gateway when protocol handling, local supervision, and analog monitoring must share one controller. Its 170 MHz Cortex-M4 performance and 512 KB Flash provide substantially more application-code capacity than small communication MCUs, while the 48-LQFP package supports both communications peripherals and external interfaces. The device is particularly relevant to gateways that translate protocols, collect equipment data, and perform local control without a separate processor. Exact UART, USB, CAN, Ethernet, or other interface availability was not present in the supplied data, so protocol and transceiver support must be confirmed before design release.
推荐
Embedded Control and Monitoring
The STM32G473CET6 fits standalone monitoring equipment that must evaluate inputs, execute embedded logic, and manage local outputs in a compact enclosure. The Cortex-M4F core handles floating-point and control calculations at up to 170 MHz, while 512 KB of Flash supports diagnostics, event logging, configuration, and update routines. The 48-LQFP 7 x 7 mm package allows access to numerous external signals without requiring a very large PCB. Before deployment, confirm the operating-temperature grade, ADC performance, watchdog behavior, supply range, and brownout behavior because those specifications were not included in the retrieved search excerpts.

设计说明
Confirm the complete STM32G473CE supply-voltage and decoupling requirements from the manufacturer documentation before schematic release. The verified data establishes a 170 MHz Cortex-M4 MCU with high-performance analog capability, but it does not provide the operating supply range, regulator requirements, or pin-specific analog-supply constraints. Place the required input, output, and analog-reference capacitors at their designated pins, and review power-up, brownout, and analog-reference sequencing rather than inferring them from the CPU frequency.
Use the official 48-LQFP 7 x 7 mm land pattern and verify pin-1 orientation against the manufacturer package drawing. Keep analog inputs, references, and sensitive communications routes away from noisy switching nodes and high-current paths. Because the part combines a 170 MHz digital core with high-performance analog resources, return paths and ground planning should be reviewed as an analog-and-digital mixed-signal layout rather than as a purely digital MCU board.
Validate thermal performance using the manufacturer's electrical characteristics and the final board construction. The available data confirms the MCU and LQFP-48 package but does not provide junction temperature, package thermal resistance, or maximum dissipation values. Ambient temperature, regulator efficiency, nearby heat sources, copper area, and the selected temperature grade can materially affect reliability. Do not assign a thermal limit or estimated junction temperature until those verified inputs and the final PCB are available.
Do not treat the STM32G474 and temperature-grade ordering suffixes as guaranteed drop-in firmware equivalents without review. The listed alternatives retain the LQFP-48 footprint, 170 MHz core, and 512 KB Flash basis, but device-line peripherals, clock details, analog characteristics, and qualified temperature limits may differ. Review the official feature tables, errata, pin definitions, bootloader support, and firmware migration notes before substituting any alternative into production hardware.
合规信息
The supplied product and cross-reference snippets did not provide verified target-part declarations for RoHS, REACH, lead-free status, halogen-free status, conflict minerals, or automotive qualification. The generic comparison page mentions RoHS and REACH, but that does not establish compliance for STM32G473CET6.
