Overview
STM32G473VCT3TR 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 operational amplifiers, and three FDCAN controllers - deployed in industrial motor control, digital power supplies, and precision sensor signal conditioning.
For engineers reviewing the STM32G473VCT3TR datasheet, STM32G473VCT3TR pinout, STM32G473VCT3TR application, or STM32G473VCT3TR equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, CORDIC/FMAC hardware accelerators for real-time math, 5 V-tolerant GPIOs, UCPD interface for USB Type-C™ PD, and LQFP100 package with 80 fast I/Os supporting timer-encoded PWM and quadrature decoding.
Technical Context
The STM32G473VCT3TR 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 memory subsystem includes 512 KB dual-bank Flash (ECC, PCROP, read-while-write), 96 KB SRAM with parity on first 32 KB, and 32 KB CCM-SRAM with parity on instruction/data bus.
Analog integration comprises five independent 12-bit ADCs (up to 42 channels, 0–3.6 V range, 16-bit oversampling), seven DAC channels (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail op-amps (all terminals accessible, PGA mode supported), and three ultra-fast comparators - all synchronized via shared trigger routing and DMA request multiplexing.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G473VCT3TR operates at up to 170 MHz with 213 DMIPS performance, achieved via the Arm Cortex-M4 core with FPU and ART Accelerator enabling zero-wait-state execution from Flash. This frequency is validated across the full industrial temperature range (–40 °C to +85 °C) under 1.71–3.6 V supply conditions, with sustained performance confirmed by ST's DS12712 Rev 5 characterization data.
Does this MCU support true hardware-based USB Type-C™ Power Delivery?
Yes - the STM32G473VCT3TR integrates a dedicated UCPD (USB-C Power Delivery) controller with hardware support for CC line monitoring, PD message framing, CRC calculation, and VBUS discharge control. It complies with USB PD 3.0 specifications and supports both source and sink roles without external PD controller ICs, as documented in Section 3.35 of DS12712 Rev 5.
How many ADC channels can be simultaneously sampled with hardware synchronization?
Up to five ADCs (ADC1–ADC5) can be triggered synchronously via shared timer events or software start, enabling simultaneous sampling across up to 42 channels. Each ADC supports independent configuration (resolution, sampling time, alignment), and results are DMA-routed to memory with minimal CPU intervention - verified in Section 3.18 and Table 2 of DS12712 Rev 5.
What packaging and RoHS compliance status does the STM32G473VCT3TR have?
The STM32G473VCT3TR uses a RoHS-compliant LQFP100 package (14 × 14 mm, 0.5 mm pitch) with matte tin lead finish, per STMicroelectronics' official ordering information (Section 7, DS12712 Rev 5). It meets JEDEC J-STD-020 moisture sensitivity level MSL3 and is rated for industrial temperature operation (–40 °C to +85 °C).
