Overview

STM32G473VCT6TR 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 DAC channels, six rail-to-rail op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G473VCT6TR datasheet, STM32G473VCT6TR pinout, STM32G473VCT6TR application, or STM32G473VCT6TR equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, 5 V-tolerant I/Os (up to 107 pins), FDCAN support for flexible data-rate automotive/industrial networks, UCPD interface for USB Type-C™ power delivery, and hardware-accelerated trigonometric and filtering operations.

Technical Context

The STM32G473VCT6TR implements an Arm Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses, supporting concurrent high-bandwidth transfers for ADC sampling, DAC streaming, and SPI/SAI audio I/O.

It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), a dedicated USB 2.0 full-speed PHY with LPM/BCD, and a USB Type-C™ Power Delivery controller (UCPD) with dead-battery detection - all synchronized via a multi-source clock system including 4–48 MHz HSE, 32 kHz LSE with calibration, and internal RC oscillators.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32G474RET6	Same core, Flash, and peripheral set but includes AES-256/HASH crypto accelerators and TRNG - no UCPD block.	Better suited for secure firmware OTA updates and TLS stack offload; lacks native USB-C PD control.	Select when cryptographic security outweighs USB-C PD integration - requires external PD controller for Type-C designs.
STM32H743VIT6	Higher-performance dual-core (Cortex-M7/M4), 2 MB Flash, 1 MB SRAM, no CORDIC/FMAC, no UCPD - adds Ethernet, DSI, and JPEG codec.	Targets complex HMI and edge AI inference; over-spec'd for motor control or PD adapter use cases.	Choose only if application demands >3000 DMIPS, external memory interface, or display subsystem - increases cost and power by ~3×.

Compared with STM32G473VCT6TR, the STM32G474RET6 trades UCPD for cryptographic acceleration - ideal for secure IoT nodes but unsuitable for USB-C PD endpoints; the STM32H743VIT6 delivers raw performance at the expense of analog integration and power efficiency - best reserved for applications needing display or networking beyond G4 capabilities.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32G473VCT6TR operates at up to 170 MHz with an ART Accelerator enabled, achieving 213 DMIPS (Dhrystone 2.1). This performance is sustained across the full industrial temperature range (–40°C to +85°C) with VDD ≥ 2.7 V, verified per DS12712 Rev 5 Section 5.3.1.

Does this MCU support USB Type-C™ Power Delivery without external components?

Yes - the integrated UCPD controller handles CC line detection, VCONN power switching, PD message parsing, and policy engine execution per USB PD 3.0 specification. No external PD controller IC is required, though external transceivers may be needed depending on port configuration.

How many ADC channels are available, and what is the effective resolution with oversampling?

It features five independent 12-bit ADCs with up to 42 input channels. With hardware oversampling and decimation, resolution extends to 16 bits at reduced sampling rate (e.g., 12-bit @ 2.5 MSPS → 16-bit @ 156 kSPS), as specified in Section 3.18 and Table 18 of DS12712 Rev 5.

Is the LQFP100 package RoHS-compliant and lead-free?

Yes - the STM32G473VCT6TR in LQFP100 (1L package code) is RoHS-compliant, lead-free, and qualified to JEDEC J-STD-020 moisture sensitivity level 3. Full environmental compliance documentation is available in ST's ECOPACK2 database under part number STM32G473VCT6TR.
