STMicroelectronics STM32G473VET6

Overview

STM32G473VET6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, delivering 170 MHz/213 DMIPS performance, 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), seven 12-bit DACs, six operational amplifiers, and three FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G473VET6 datasheet, STM32G473VET6 pinout, STM32G473VET6 application, or STM32G473VET6 equivalent, key selection criteria include its dual-bank Flash with PCROP, CORDIC/FMAC math accelerators, 5 V-tolerant I/Os, ultra-fast comparators, and UCPD interface for USB Type-C™ power delivery implementation.

Technical Context

The STM32G473VET6 implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes 512 KB dual-bank Flash with ECC and read-while-write capability, plus 96 KB SRAM with parity on first 32 KB and 32 KB CCM-SRAM with parity on instruction/data bus.

Analog integration features five independent 12-bit ADCs (up to 42 channels, 0.25 µs conversion), seven 12-bit DACs (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail op-amps configurable as PGAs, and three FDCAN controllers supporting flexible data-rate up to 5 Mbps - all synchronized via a multi-AHB interconnect matrix and 14 timers including three advanced motor-control timers with dead-time generation.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32G473VET6 operates at up to 170 MHz with an ART Accelerator enabling zero-wait-state Flash execution, 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 true hardware random number generation?

Yes - the STM32G473VET6 integrates a certified True Random Number Generator (RNG) compliant with NIST SP800-90B and AIS-31 standards. It delivers entropy at up to 10 Mbit/s and is accessible via the RCC RNG clock enable and RNG_CR/RNG_SR registers, with output validated in Section 3.23 of the datasheet.

How many independent ADC instances does the device provide, and what is their maximum sampling rate?

The device integrates five independent 12-bit ADCs (ADC1–ADC5), each capable of 0.25 µs conversion time (4 MSPS). They support simultaneous sampling across up to 42 channels with hardware oversampling up to 16-bit resolution, as detailed in Sections 3.18 and Table 2 of DS12712 Rev 5.

Is the UCPD peripheral capable of full USB Power Delivery 3.0 compliance?

Yes - the integrated UCPD controller supports USB PD 3.0 specification including structured VDMs, SOP'/SOP" messages, Fast Role Swap, and programmable CC logic. It handles BMC decoding, CRC validation, and policy engine state machine in hardware, eliminating need for external PD controllers per Section 3.35 of the datasheet.
