Product details
Overview
STM32G473VCH3TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, 512 KB Flash (ECC-enabled), 170 MHz max CPU frequency (213 DMIPS), and integrated CORDIC/FMAC math accelerators. It features 5×12-bit ADCs (0.25 µs conversion), 7×12-bit DACs (including 3 buffered external channels at 1 MSPS), and 6 operational amplifiers usable in PGA mode - deployed in motor control, digital power conversion, and industrial sensor fusion systems.
For engineers reviewing the STM32G473VCH3TR datasheet, STM32G473VCH3TR pinout, STM32G473VCH3TR application, or STM32G473VCH3TR equivalent, key selection criteria include its dual-bank read-while-write Flash architecture, 32 kHz RTC with alarm and wakeup, FDCAN support for flexible data-rate automotive networks, and UCPD interface for USB Type-C™ power delivery control.
Technical Context
The STM32G473VCH3TR implements a tightly coupled Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals via multiple AHB/APB buses.
It integrates three dedicated advanced motor control timers (TIM1/TIM8/TIM20) with 8-channel PWM, dead-time generation, and emergency stop - alongside 3×FDCAN controllers compliant with ISO 11898-1:2015, supporting bit rates up to 5 Mbps in FD mode and seamless legacy CAN 2.0B interoperability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KBU6 | Same G4 series, but 128 KB Flash, no CORDIC/FMAC, 48-pin UFQFPN - lacks math acceleration and dual-bank RWW capability. | Suitable for cost-sensitive motor gate drivers or basic digital power where complex math is handled externally. | Select when full 512 KB Flash and hardware math acceleration are not required; lower BOM cost and smaller footprint. |
| STM32H743VIT6 | Cortex-M7 core, 1 MByte Flash, 480 MHz, D-cache, TCM RAM - higher performance but larger package (LQFP100), no UCPD or FDCAN FD. | Better for AI inference at edge or high-resolution graphics UI; overqualified for FOC or USB-C PD control alone. | Choose only if application requires >213 DMIPS, dual-core capability, or external SDRAM interface - not a drop-in replacement. |
Compared with STM32G431KBU6, the STM32G473VCH3TR delivers 4× more Flash, deterministic math acceleration, and FDCAN FD - essential for evolving automotive and industrial protocols. Versus STM32H743VIT6, it offers superior analog integration, USB-C PD support, and lower power in compact 48-pin form - making it optimal for embedded power electronics.

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32G473VCH3TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone 2.1). This is achieved with the ART Accelerator enabled and Flash prefetch disabled, ensuring deterministic execution timing for hard real-time control loops without cache-induced jitter.
Does this MCU support USB Type-C™ Power Delivery negotiation?
Yes - the STM32G473VCH3TR integrates a full USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0 specification. It handles physical layer signaling, BMC decoding, and PD message parsing without external transceivers, supporting source/sink roles and vendor-defined messages.
How many analog-to-digital converters does it include, and what are their key specs?
It includes five independent 12-bit ADCs with up to 42 input channels, 0.25 µs conversion time, and hardware oversampling up to 16-bit resolution. Each ADC supports injected/conversion modes, analog watchdogs, and precise synchronization with timers - optimized for multi-axis motor current sampling and power quality monitoring.
What low-power modes are available, and what is the lowest achievable current draw?
The device supports Sleep, Stop, Standby, and Shutdown modes. In Standby mode with RTC running and 32-bit backup registers retained, typical current consumption is 1.3 µA at 25°C. Wakeup latency from Stop mode is <5 µs, enabling rapid response to sensor interrupts while maintaining µA-level average power in duty-cycled applications.
