Product details
Overview
STM32G474VET3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six rail-to-rail op-amps, and a high-resolution timer (HRTIM) with 184 ps resolution-designed for precision motor control and digital power conversion.
For engineers reviewing the STM32G474VET3 datasheet, STM32G474VET3 pinout, STM32G474VET3 application, or STM32G474VET3 equivalent, key selection considerations include HRTIM timing precision, dual-bank Flash read-while-write capability, CORDIC/FMAC hardware accelerators for real-time math, and FDCAN support for automotive-grade communication.
Technical Context
The STM32G474VET3 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and dual-bank Flash architecture supporting seamless firmware updates. Its interconnect matrix routes up to 107 GPIOs-including 5 V-tolerant pins-to multiple peripherals without bus contention.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (FD mode), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated UCPD controller for USB Type-C™ power delivery negotiation-enabling single-chip implementation of programmable power supplies and bidirectional charging systems.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G473VET3 | No FDCAN; 384 KB Flash; no UCPD; same HRTIM/ADC/DAC/peripheral set | Suitable for non-automotive motor control where CAN FD or USB-C PD is not required | Select when cost sensitivity outweighs need for FDCAN/UCPD-retains identical analog performance and timing precision |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz; 2 MB Flash; 1 MB RAM; no HRTIM; dual ADCs only; no CORDIC/FMAC | Better for high-throughput data processing (e.g., vision, AI inference), weaker for ultra-precise PWM timing | Choose for compute-intensive tasks needing higher clock speed and memory bandwidth-not for sub-ns PWM or analog-rich control |
Compared with STM32G473VET3, the STM32G474VET3 adds FDCAN and UCPD for automotive and USB-C power applications; versus STM32H743VIT6, it trades raw CPU throughput for superior analog integration, deterministic timing (HRTIM), and domain-specific accelerators (CORDIC/FMAC).

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32G474VET3 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 zero-wait-state Flash execution. The FPU supports single-precision floating-point operations, and the MPU enforces memory access protection for safety-critical applications.
Does this MCU support true hardware-based USB Type-C™ power delivery negotiation?
Yes-the STM32G474VET3 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It handles BMC physical layer signaling, PD message parsing, policy engine execution, and VCONN switching without external components, enabling compact, certified USB-C power sink/source designs.
How does the HRTIM differ from standard advanced timers in the STM32 family?
The HRTIM delivers 184 ps timing resolution-over 5× finer than standard advanced timers-and features six independent 16-bit counters with fully synchronized PWM outputs, programmable dead time down to 184 ps, fault input mapping, and burst mode for intermittent high-precision operation. It is specifically architected for multi-phase resonant converters and high-fidelity motor control.
What analog features make this MCU suitable for precision measurement applications?
It includes five 12-bit ADCs with up to 42 channels, 0.25 µs conversion time, hardware oversampling up to 16-bit effective resolution, and independent analog supply (VDDA/VSSA) routing. Combined with six rail-to-rail op-amps (configurable as PGAs), internal VREFBUF (2.048 V/2.5 V/2.9 V), and temperature sensor, it supports high-accuracy sensor conditioning and ratiometric measurements without external signal chain components.
