STMicroelectronics STM32G473VCT6

Overview

STM32G473VCT6 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 5×12-bit ADCs (0.25 µs), 7×12-bit DACs, 6 op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G473VCT6 datasheet, STM32G473VCT6 pinout, STM32G473VCT6 application, or STM32G473VCT6 equivalent, key selection criteria include its LQFP100 package with 80 fast I/Os (5 V tolerant), triple FDCAN support for automotive-grade communication, hardware RNG and cryptographic acceleration readiness, and dual-bank Flash with PCROP for secure firmware updates.

Technical Context

The STM32G473VCT6 implements an Arm Cortex-M4 core with floating-point unit and DSP extensions, coupled with ST's Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes 512 KB dual-bank Flash (ECC, PCROP, 1 KB OTP) and 128 KB SRAM (96 KB general + 32 KB CCM with parity).

Analog integration features five independent 12-bit ADCs (up to 42 channels, 0.25 µs conversion), seven 12-bit DAC channels (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail op-amps configurable as PGAs, and dedicated hardware accelerators: CORDIC for trigonometric computation and FMAC for FIR/IIR filtering - all synchronized via a multi-AHB interconnect matrix and 16-channel DMA controller.

Key Specifications

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32G473VCT6 operates at up to 170 MHz with an integer performance of 213 DMIPS, measured using the Dhrystone 2.1 benchmark with ART Accelerator enabled and zero-wait-state Flash execution. This rating assumes full utilization of the Cortex-M4 core with FPU and DSP extensions under typical silicon conditions (25°C, 3.3 V).

Does the device support hardware encryption or secure boot features?

The STM32G473VCT6 does not integrate AES, HASH, or PKA cryptographic accelerators. It supports secure boot via proprietary code readout protection (PCROP) and securable memory areas in Flash, but lacks dedicated crypto engines - unlike the STM32G474 variant. Secure firmware updates rely on software-implemented algorithms or external secure elements.

How many ADC channels can be simultaneously sampled with hardware synchronization?

Up to 16 ADC channels can be simultaneously sampled using hardware synchronization across the five independent 12-bit ADCs, leveraging the common trigger source (e.g., TIM1 TRGO) and shared DMA request. This capability is confirmed in Section 3.18 of DS12712 Rev 5 and enables precise multi-sensor acquisition for motor phase current or power converter monitoring.

What debug interfaces are supported, and is SWD sufficient for full development?

The STM32G473VCT6 supports Serial Wire Debug (SWD) and JTAG via the SWJ-DP interface. SWD is fully sufficient for programming, real-time debugging, and trace (with ETM support), requiring only two pins (SWCLK/SWDIO). No external debugger license or additional hardware is needed beyond standard ST-LINK probes for full development and production programming.
