Product details
Overview
STM32G474VET7 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated high-resolution timer (HRTIM) with 184 ps resolution. It integrates CORDIC and FMAC math accelerators, seven 12-bit DACs, five 12-bit ADCs (up to 42 channels), and three FDCAN controllers - deployed in industrial motor control and digital power conversion systems.
For engineers reviewing the STM32G474VET7 datasheet, STM32G474VET7 pinout, STM32G474VET7 application, or STM32G474VET7 equivalent, key selection criteria include HRTIM timing precision for PWM generation, dual-bank Flash read-while-write capability for firmware updates, 5 V-tolerant I/O count (up to 107), analog subsystem integration (OPAMPs, COMP, VREFBUF), and USB Type-C™/PD controller (UCPD) support.
Technical Context
The STM32G474VET7 implements a tightly coupled ART Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) for secure task isolation. Its interconnect matrix routes up to 107 GPIOs across multiple AHB/APB buses, supporting concurrent high-bandwidth peripherals including FDCAN, USB FS, SAI, and QUADSPI.
It features a deterministic real-time analog subsystem: six rail-to-rail op-amps (configurable as PGAs), seven comparators, and a dedicated voltage reference buffer (VREFBUF) with selectable outputs (2.048 V / 2.5 V / 2.9 V). The HRTIM delivers sub-nanosecond PWM timing control with independent dead-time insertion and emergency stop - critical for synchronous rectification and multi-phase motor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G473VET6 | Same package and pinout; lacks UCPD controller and one FDCAN channel; 256 KB Flash | Suitable for cost-sensitive motor control where USB-C PD is not required | Select when UCPD and third FDCAN are unnecessary; lower BOM cost with identical footprint |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz; 2 MB Flash, 1 MB RAM; no HRTIM or CORDIC; dual-core option available | Better for complex GUI, Ethernet, or AI inference; less optimal for nanosecond-precision PWM | Choose for higher throughput applications requiring DSP or multimedia; avoid if HRTIM timing or analog integration is critical |
Compared with STM32G473VET6, the STM32G474VET7 adds USB-C PD control and enhanced analog integration at no pinout penalty; versus STM32H743VIT6, it trades raw CPU speed for deterministic sub-nanosecond timing and hardware math acceleration tailored to real-time power electronics.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G474VET7 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), measured under conditions of zero-wait-state Flash execution enabled by the ART Accelerator. Its FPU supports IEEE 754 single-precision operations, and the MPU allows secure partitioning of memory regions for RTOS-based applications.
Does the device support true hardware-based USB Type-C™ power delivery?
Yes - the STM32G474VET7 integrates a dedicated UCPD (USB-C Power Delivery) controller compliant with USB PD 3.0 specification. It handles physical layer signaling (CC line detection, VCONN switching), SOP′ packet transmission, and policy engine execution without external components, enabling compact, certified USB-C PD designs.
How many analog-to-digital converter channels are available, and what is their effective resolution?
The device includes five independent 12-bit ADCs supporting up to 42 total channels. With hardware oversampling, effective resolution reaches 16 bits at reduced sampling rates (e.g., 12-bit @ 2.4 MSPS or 16-bit @ 153 kSPS). All ADCs share common calibration registers and support simultaneous sampling on up to two converters for motor current reconstruction.
What low-power modes are supported, and what is the typical current draw in Stop mode?
The STM32G474VET7 supports Sleep, Stop, Standby, and Shutdown modes. In Stop mode with RTC running and SRAM retention, typical current consumption is 2.5 µA (at 25 °C, VDD = 3.3 V). Wakeup latency from Stop is ≤5 µs, and the device retains full register and SRAM content except for backup domain registers powered by VBAT.
