Overview
STM32G473VET6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash (ECC-enabled), 128 KB SRAM (96 KB + 32 KB CCM), and 170 MHz max CPU frequency delivering 213 DMIPS. It integrates dual-bank read-while-write Flash, CORDIC/FMAC math accelerators, 5×12-bit ADCs (42-channel, 0.25 µs), 7×DAC channels, 6 operational amplifiers, and 3 FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473VET6TR datasheet, STM32G473VET6TR pinout, STM32G473VET6TR application, or STM32G473VET6TR equivalent, key selection criteria include its 100-pin LQFP package, 170 MHz real-time performance with ART Accelerator, integrated analog front-end (6 OPAMPs, 7 DACs, 5 ADCs), FDCAN FD support, and UCPD USB Type-C™ controller for embedded power delivery systems.
Technical Context
The STM32G473VET6TR implements an Arm Cortex-M4 core with hardware FPU and Memory Protection Unit (MPU), paired with ST's Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix supports concurrent high-bandwidth peripheral access across AHB/APB buses.
It features three independent FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD up to 5 Mbit/s), a dedicated USB Type-C™/Power Delivery (UCPD) controller with VBUS monitoring and role swap, and dual-clock domain RTC with tamper detection - all operating within 1.71–3.6 V supply range and industrial temperature grade (–40°C to +85°C).

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same package and core; adds AES-256/HASH crypto accelerators and no UCPD block. | Better suited for secure firmware updates and encrypted communications; lacks native USB-C PD control. | Select when cryptographic security is prioritized over USB-C power management. |
| STM32H743VIT6 | Higher-tier Cortex-M7 (480 MHz), 2 MB Flash, dual-core option, no CORDIC/FMAC, no UCPD. | Targeted at high-throughput HMI or AI-edge inference; requires external USB-C PD IC for power negotiation. | Select for compute-intensive tasks where math acceleration is handled in software or external FPGA. |
Compared with STM32G473VET6TR, the STM32G474RET6 trades UCPD for cryptographic acceleration-ideal for secure industrial gateways-while the STM32H743VIT6 offers higher clock speed and memory but removes integrated analog math engines and USB-C PD, increasing BOM count and firmware complexity for power delivery systems.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32G473VET6TR achieves 170 MHz maximum CPU frequency using the Adaptive Real-Time (ART) Accelerator, which provides zero-wait-state execution from Flash memory. This is validated across the full industrial temperature range (–40°C to +85°C) with VDD ≥ 2.7 V and confirmed in DS12712 Rev 5 Section 5.3.1. The ART Accelerator includes prefetch and branch cache, eliminating instruction fetch bottlenecks.
Does this MCU support USB Type-C™ Power Delivery negotiation?
Yes - the STM32G473VET6TR integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller (Section 3.35 of DS12712). It handles physical layer signaling, BMC encoding/decoding, SOP packet parsing, and policy engine execution, enabling full source/sink/host/device role negotiation without external PD controller ICs.
How many ADC channels are available and what is their effective resolution?
The device integrates five independent 12-bit ADCs supporting up to 42 total channels. With hardware oversampling (up to ×256), effective resolution reaches 16 bits (DS12712 Section 3.18), verified by ENOB measurements in typical conditions. Each ADC supports simultaneous sampling, injected/conversion modes, and analog watchdogs.
What debug interfaces are supported and are they available in production?
Serial Wire Debug (SWD) and JTAG are fully supported and enabled in production silicon (DS12712 Section 3.39). SWD uses SWCLK/SWDIO pins (PA14/PA13) and is recommended for space-constrained layouts; JTAG uses five pins (TCK/TMS/TDI/TDO/nTRST) and supports boundary scan. Both interfaces operate across full voltage and temperature ranges.
