STMicroelectronics STM32G474MET6TR

Overview

STM32G474MET6TR 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 DACs, six operational amplifiers, and a high-resolution timer (HRTIM) with 184 ps resolution - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G474MET6TR datasheet, STM32G474MET6TR pinout, STM32G474MET6TR application, or STM32G474MET6TR equivalent, key selection criteria include HRTIM timing precision for PWM dead-time control, dual-bank Flash with read-while-write for firmware updates, CORDIC/FMAC hardware accelerators for real-time trigonometric and filtering math, and FDCAN FD support for automotive/industrial networking.

Technical Context

This MCU implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and dual-bank Flash architecture supporting seamless firmware updates. Its interconnect matrix routes 107 GPIOs, 16-channel DMA, and multiple bus masters (CPU, DMA, FSMC) without contention.

The analog subsystem integrates three buffered external DACs (1 MSPS), four unbuffered internal DACs (15 MSPS), seven rail-to-rail comparators, and six op-amps configurable as programmable-gain amplifiers (PGA) with all terminals accessible - enabling closed-loop control signal conditioning directly on-die.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32G474MET6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS). This is achieved with the ART Accelerator enabled and zero-wait-state Flash execution. The FPU supports single-precision floating-point operations compliant with IEEE 754, and the MPU enforces memory access permissions for robust real-time task isolation.

Does this MCU support true hardware-based USB Type-C Power Delivery?

Yes - the STM32G474MET6TR integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It handles BMC physical layer signaling, PD message parsing, policy engine execution, and VBUS switch control without external components. The UCPD peripheral operates independently of the CPU, enabling low-latency fault response and autonomous renegotiation.

How does the HRTIM differ from standard general-purpose timers in this device?

The HRTIM is a dedicated high-resolution timer subsystem with six independent 16-bit counters, 184 ps timing resolution (vs. ~6 ns for standard timers), and hardware-implemented dead-time insertion, fault protection, and synchronous ADC triggering. Unlike TIM1/TIM8, it supports complex waveform building (e.g., complementary PWM with phase shift, burst mode) and operates autonomously from CPU intervention.

What analog features make this MCU suitable for sensor signal conditioning?

It integrates six fully accessible operational amplifiers configurable as PGAs (gain 1–16), seven rail-to-rail comparators with programmable hysteresis, an internal voltage reference buffer (VREFBUF) with selectable 2.048 V/2.5 V/2.9 V outputs, and five 12-bit ADCs with hardware oversampling up to 16-bit effective resolution - enabling complete front-end signal chain implementation without external op-amp or reference ICs.
