Product details
Overview
STM32G473MCT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating 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. It targets motor control, digital power conversion, and industrial sensing systems requiring real-time math acceleration and high-precision analog signal chain integration.
For engineers reviewing the STM32G473MCT6TR datasheet, STM32G473MCT6TR pinout, STM32G473MCT6TR application, or STM32G473MCT6TR equivalent, key selection criteria include its CORDIC/FMAC hardware accelerators for trigonometric and filtering operations, dual-bank Flash with read-while-write capability, 5 V-tolerant I/Os across 107 pins, and UCPD interface for USB Type-C™ power delivery implementation.
Technical Context
The STM32G473MCT6TR implements an Arm Cortex-M4 core with floating-point unit and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes two independent Flash banks supporting concurrent read/write and secure code protection via PCROP and securable memory areas.
Analog integration centers on a multi-channel, time-synchronized signal acquisition architecture: five 12-bit ADCs share common timing and can be triggered synchronously; seven DACs include three buffered external outputs (1 MSPS) and four unbuffered internal outputs (15 MSPS); six op-amps support programmable gain amplifier (PGA) mode with all terminals accessible for external feedback.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G473MCT6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), measured using the ARM Dhrystone benchmark v2.1 under conditions of zero-wait-state Flash execution enabled by the ART Accelerator. This frequency is sustained across the full industrial temperature range (–40°C to +85°C) with VDD ≥ 2.7 V.
Does this MCU support true hardware random number generation?
Yes, the STM32G473MCT6TR integrates a certified True Random Number Generator (RNG) compliant with NIST SP800-90B and AIS-31 standards. It delivers entropy via a dedicated hardware block using analog noise sources and includes built-in health tests and statistical validation logic to ensure cryptographic-grade randomness for key generation and secure boot.
How many ADCs does it have, and what is their synchronization capability?
The device integrates five independent 12-bit ADCs with up to 42 total input channels and 0.25 µs conversion time. All five ADCs support hardware-synchronized start triggers via shared timer events, enabling simultaneous sampling across multiple phases - essential for accurate three-phase motor current reconstruction and multi-sensor acquisition.
Is the UCPD interface capable of full USB Power Delivery 3.0 compliance?
Yes, the integrated USB Type-C™ and Power Delivery (UCPD) controller supports USB PD 3.0 specification, including Programmable Power Supply (PPS), Fast Role Swap (FRS), and extended message support. It handles physical layer signaling on CC lines, PD protocol stack execution, and power role negotiation without requiring external PD controller ICs.
