Product details
Overview
STM32G473VET3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, 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 operational amplifiers, and three FDCAN controllers. It targets motor control, digital power conversion, and industrial sensing systems requiring real-time math acceleration via CORDIC and FMAC.
For engineers reviewing the STM32G473VET3 datasheet, STM32G473VET3 pinout, STM32G473VET3 application, or STM32G473VET3 equivalent, key selection criteria include its 170 MHz Cortex-M4+FPU core, dual-bank Flash with read-while-write capability, 107 fast I/Os (5 V tolerant on selected pins), USB 2.0 FS + UCPD for USB Type-C™ PD, and hardware math accelerators for trigonometric and filtering operations.
Technical Context
The STM32G473VET3 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz, paired with a Memory Protection Unit (MPU) and DSP instruction set for deterministic real-time control. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals without bus contention.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (flexible data-rate), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated USB Type-C™/PD controller (UCPD) with VBUS monitoring and CC line control - all co-located with high-resolution timers (up to 16-bit, 8-channel advanced motor control timers with dead-time generation) for synchronized power stage control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KBU6 | Same G4 series, but 128 KB Flash, 32 KB SRAM, LQFP32 package, no CORDIC/FMAC, single ADC (12-bit, 1.14 MSPS), 2× FDCAN | Suitable for cost-sensitive motor control where math acceleration and dual-bank Flash are not required | Select when BOM cost reduction outweighs need for hardware trigonometric acceleration and firmware update flexibility. |
| STM32H743VIT6 | Higher-tier Cortex-M7 @ 480 MHz, 2 MB Flash, 1 MB SRAM, dual-core option, no CORDIC/FMAC, but includes DWT and L1 cache | Targeted at complex HMI + control fusion, AI inference at edge, or multi-axis CNC motion control | Choose when >200 DMIPS, Ethernet, or dual-core RTOS partitioning is mandatory - not drop-in compatible due to pinout and peripheral differences. |
Compared with STM32G473VET3, the STM32G431KBU6 trades math acceleration and memory density for lower cost and smaller footprint, while the STM32H743VIT6 offers higher throughput and memory bandwidth at the expense of power efficiency and analog integration - making the G473VET3 optimal for analog-rich, real-time deterministic applications within 170 MHz performance envelope.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G473VET3?
The STM32G473VET3 operates at up to 170 MHz with an ART Accelerator enabling zero-wait-state Flash execution. Its performance is rated at 213 DMIPS (Dhrystone 2.1), verified under conditions of 170 MHz clock, 1.71–3.6 V supply, and –40 °C to +85 °C ambient temperature per DS12712 Rev 5 Section 3.1.
Does the STM32G473VET3 support hardware-accelerated mathematical functions, and if so, which ones?
Yes - it includes two dedicated hardware accelerators: CORDIC for trigonometric, hyperbolic, and square-root functions, and FMAC for configurable FIR filtering. Both operate independently of the CPU, with CORDIC delivering results in ≤15 cycles and FMAC supporting up to 32-tap filters with 32-bit MAC operations, as specified in Sections 3.8 and 3.9 of the datasheet.
What are the supported package types and pin counts for the STM32G473VET3?
The STM32G473VET3 is exclusively offered in LQFP100 (14 × 14 mm, 0.5 mm pitch) package with 100 pins. This is confirmed in Table 1 (Device Summary) and Section 6.8 (LQFP100 package information) of DS12712 Rev 5, and distinguishes it from other G473 variants like the VCT6 (LQFP100) or VET6 (LQFP100) - the '3' suffix denotes industrial temperature grade.
How does the STM32G473VET3 handle USB Type-C™ power delivery functionality?
It integrates a dedicated USB Type-C™ and Power Delivery controller (UCPD) with hardware support for CC line monitoring, VBUS sensing/discharge, and PD message parsing. The UCPD operates alongside the USB 2.0 full-speed interface, enabling complete PD sink/source negotiation without external PHY - detailed in Section 3.35 and electrical characteristics Table 29 of DS12712 Rev 5.
