Product details
Overview
STM32G474QET6TR 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, 96 KB SRAM (including 32 KB CCM-SRAM with parity), and integrated analog peripherals including 5×12-bit ADCs (0.25 µs conversion), 7×12-bit DACs, 6 operational amplifiers, and HRTIM with 184 ps resolution. It targets high-precision motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G474QET6TR datasheet, STM32G474QET6TR pinout, STM32G474QET6TR application, or STM32G474QET6TR equivalent, key selection criteria include HRTIM timing precision for PWM generation, dual-bank Flash for seamless firmware updates, CORDIC/FMAC acceleration for real-time math, and UCPD support for USB Type-C™ power delivery implementations.
Technical Context
The device implements an Adaptive Real-Time Accelerator (ART) enabling zero-wait-state execution from Flash memory, critical for deterministic real-time control loops. 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 (FD mode), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated UCPD controller for USB Type-C™ port negotiation and power role management - all coexisting with high-resolution analog subsystems.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G474QET6TR operates at up to 170 MHz, delivering 213 DMIPS (Dhrystone MIPS) with the ART Accelerator enabled. This performance level is sustained with zero-wait-state execution from Flash memory, verified under standard conditions (VDD = 3.3 V, TA = 25 °C) per DS12288 Rev 6 Section 5.3.1.
Does this MCU support USB Type-C™ Power Delivery negotiation?
Yes-it integrates a dedicated USB Type-C™ / USB Power Delivery (UCPD) controller compliant with USB PD 3.0 specifications. The UCPD block handles BMC physical layer signaling, policy engine execution, VBUS monitoring, and discharge control without external components, as documented in Section 3.35 of the datasheet.
How many analog-to-digital converter channels does it provide, and what is their speed?
The device integrates five independent 12-bit ADCs supporting up to 42 total channels, with a minimum conversion time of 0.25 µs (4 MSPS). Resolution can be extended to 16-bit using hardware oversampling, and the conversion range spans 0 to 3.6 V, per Section 3.18 and Table 5.3.19.
Is the HRTIM module capable of generating complementary PWM outputs with programmable dead time?
Yes-the High-Resolution Timer (HRTIM) provides six 16-bit timers with 184 ps resolution and built-in dead-time insertion logic. It supports complementary PWM output pairs with configurable dead-time (down to 184 ps steps) and emergency shutdown inputs, as specified in Section 3.24.1 and Table 5.3.16.
