Product details
Overview
STM32G474MET3TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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 5×12-bit ADCs (0.25 µs), 7×12-bit DACs, 6 operational amplifiers, and a 184-ps-resolution HRTIM - deployed in industrial motor control, digital power conversion, and precision sensor processing systems.
For engineers reviewing the STM32G474MET3TR datasheet, STM32G474MET3TR pinout, STM32G474MET3TR application, or STM32G474MET3TR equivalent, key selection considerations include its dual-bank read-while-write Flash architecture, CORDIC/FMAC hardware accelerators for real-time math, FDCAN FD support, UCPD interface for USB Type-C PD, and LQFP80 package with 80-pin 0.5 mm pitch.
Technical Context
The STM32G474MET3TR implements an adaptive real-time memory accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix supports concurrent access by CPU, DMA, and peripherals to multiple bus domains (AHB/APB).
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated USB Type-C™/PD controller (UCPD) with VBUS discharge and CC line monitoring - all coexisting with high-resolution analog subsystems and deterministic timer hierarchies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G473RET6 | Same core/peripherals but 256 KB Flash, no UCPD, no FDCAN FD (only classic CAN) | Suitable for cost-sensitive motor control without USB-C PD or CAN FD requirements | Select when USB-C PD and CAN FD are not required and Flash budget is ≤256 KB. |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB Flash, dual-core option, no HRTIM or CORDIC, higher power envelope | Targeted at high-throughput HMI + control fusion (e.g., PLC + display), not ultra-low-latency analog control | Choose for applications needing >200 MHz compute headroom and large code footprint, accepting larger package and higher static current. |
Compared with STM32G474MET3TR, the STM32G473RET6 reduces feature set to lower cost and power, while the STM32H743VIT6 trades analog precision and sub-ns timing for raw throughput and memory - making the G474 optimal for deterministic, mixed-signal edge control where latency and analog integration outweigh peak MIPS.
