STM32G473VBT6 - 170MHz 128KB Cortex-M4 | STMicroelectronics
料号： STM32G473VBT6 ✓ 量产中STM32G473VBT6 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The STM32G4 family combines the Arm Cortex-M4 processor architecture with embedded control peripherals, analog conversion resources, and dedicated hardware acceleration. Within the broader hierarchy, the STM32G473VBT6 is a 32-bit microcontroller, a member of the STM32G4 series, and a device intended for industrial, instrumentation, and embedded-control applications.
Verified product information identifies three headline capabilities: a maximum clock frequency of 170 MHz, 128 KB of Flash memory, and a math accelerator. The part also provides high analog-level integration and operates across 1.8 V, 2.5 V, and 3.3 V supply configurations identified in the verified listing data. These characteristics make it suitable for designs requiring faster control-loop execution than many general-purpose Cortex-M microcontrollers while retaining the simplicity of a single-chip embedded architecture.
The Arm Cortex-M4 core provides 32-bit instruction processing, while the dedicated math accelerator offloads suitable mathematical operations from the main processor. This division can improve execution efficiency in applications involving digital filters, transforms, and other arithmetic-intensive signal-processing tasks. The 128 KB embedded Flash provides fixed-program storage without requiring an external memory device for typical firmware and configuration data.
Typical uses include industrial motor and power-system control, precision measurement equipment, data-acquisition systems, communications controllers, and mixed-signal embedded products. The combination of 170 MHz processing, math acceleration, and high analog integration can simplify a design by consolidating control and analog functions rather than distributing them across multiple discrete components.
Engineering design should account for the 100-LQFP footprint, verify the exact peripheral assignment against the manufacturer datasheet, and use the manufacturer-recommended decoupling and clock arrangements. Board layout must also provide adequate thermal and signal-return paths for the high-pin-count mixed-signal device.
This product page consolidates verified distributor availability, the 6.4182 USD listed unit price as of 2026-10-29, same-family drop-in alternatives, and practical design guidance. It also distinguishes the STM32G473VBT6 from alternatives that change Flash capacity, analog capability, or temperature grade.

典型应用
STM32G473VBT6 适用于 6 应用s: Industrial Motor Control, Precision Data Acquisition, Digital Signal Conditioning, Power-System Monitoring, Communications Controller, Instrumentation and Test Equipment.
Industrial Motor Control
The STM32G473VBT6 is appropriate for compact industrial motor-control systems that benefit from 170 MHz real-time processing and high analog integration. Its Arm Cortex-M4 core can execute timing-critical control loops, while the dedicated math accelerator supports arithmetic-heavy calculations without relying on an external accelerator. The 128 KB of embedded Flash accommodates firmware, parameter tables, and control logic in one package. A designer should verify whether the exact timers, ADC channels, comparators, and motor-control peripherals required by the drive are present before committing to the device.
推荐
Precision Data Acquisition
The STM32G473VBT6 can serve as the processing center of a precision data-acquisition instrument because it combines a 170 MHz Cortex-M4 core with high analog integration. The verified LCSC listing identifies 12-bit conversion resources, while the 128 KB Flash can hold acquisition firmware and calibration tables. The integrated math accelerator can assist digital filtering and other arithmetic operations after samples are captured. Engineers must confirm the required sample rate, channel count, analog accuracy, reference arrangement, and acquisition-trigger functions in the manufacturer datasheet.
推荐
Digital Signal Conditioning
The STM32G473VBT6 fits digital signal-conditioning designs that need deterministic control and arithmetic performance in one microcontroller. At up to 170 MHz, the Cortex-M4 core can manage sampling schedules, state machines, and communications, while the hardware math accelerator reduces the processing burden associated with suitable filter and transform operations. Its 128 KB Flash provides a fixed repository for signal-processing firmware. Final implementation still requires checking the required sampling rate, numerical format, DMA behavior, and peripheral interaction against the exact STM32G473 documentation.
推荐
Power-System Monitoring
The STM32G473VBT6 is suitable for monitoring and control functions in embedded power systems where a 170 MHz Cortex-M4 core can execute fast measurement and supervisory logic. High analog integration supports mixed-signal designs, and the math accelerator can help implement arithmetic processing after measurements are acquired. The 128 KB Flash supports embedded control code without an external program-memory component in typical designs. Engineers should verify the required ADC performance, comparator resources, timer behavior, operating-voltage limits, and safety margins in the manufacturer datasheet before schematic release.
推荐
Communications Controller
The STM32G473VBT6 can act as the central controller in a communications-oriented embedded product that benefits from 170 MHz processing and extensive pin availability. The 100-LQFP package exposes more connections than compact MCU packages, making it practical to allocate pins to serial interfaces, control signals, indicators, and status monitoring. Its 128 KB Flash is sufficient for many protocol stacks and application firmware, although the exact RAM requirement is not present in the verified data. Designers should confirm UART, USB, CAN, Ethernet support, pin multiplexing, and protocol timing before selecting the part.
推荐
Instrumentation and Test Equipment
The STM32G473VBT6 can serve as the main embedded controller in instrumentation and test equipment requiring a compact mix of control, computation, and analog functionality. Its 170 MHz Cortex-M4 core handles instrument commands and real-time sequencing, while the math accelerator supports arithmetic-intensive measurement algorithms. The 128 KB Flash holds firmware and test definitions, and the high analog integration can reduce external component count. The design must still verify the required conversion performance, external-interface mapping, calibration strategy, reference-noise behavior, and operating-temperature limits before production release.

设计说明
Use the manufacturer's 100-LQFP footprint and land pattern exactly as shown in the package drawing; do not infer it solely from the 14 x 14 mm body size. Reserve short, direct routes for the oscillator, reset, debug, and decoupling pins, and place input and output capacitors close to their associated supply pins. Because this is a high-pin-count mixed-signal MCU, verify every alternate-function assignment against the datasheet before routing. A pinout was not present in the supplied web snippets, so no pin-level routing guidance was fabricated.
The verified product listings identify 1.8 V, 2.5 V, and 3.3 V operating configurations, but they do not provide the full power-supply tolerance, decoupling, or current-budget tables. Select the exact supply rails from the manufacturer recommendations and verify the resulting voltage against all core, analog, and I/O operating ranges. Place bulk and high-frequency decoupling according to the datasheet guidance, and keep analog and digital return currents separated where the reference layout calls for it.
The 170 MHz operating class requires disciplined clock and signal-return design even though the final clock configuration must be confirmed in the datasheet. Use short traces for high-speed nets, provide a continuous ground reference under the device, avoid routing sensitive analog inputs beside fast digital clocks, and follow the manufacturer layout for decoupling and analog guarding. A compact LQFP package does not by itself guarantee low-noise measurement performance; component placement and reference-network design remain critical.
合规信息
The verified results mention RoHS and REACH only as comparison attributes but do not provide their actual status. Compliance must be confirmed from the manufacturer product page or declaration.
