Product details
Overview
STM32G473MET6 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 hardware math accelerators (CORDIC, FMAC). It targets motor control, digital power conversion, and industrial sensing systems requiring real-time signal processing and high-precision analog I/O.
For engineers reviewing the STM32G473MET6 datasheet, STM32G473MET6 pinout, STM32G473MET6 application, or STM32G473MET6 equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, 5 V-tolerant GPIOs (up to 107), FDCAN support for flexible data-rate automotive/industrial networks, UCPD interface for USB Type-C™ power delivery, and low-power timer with sub-microsecond resolution for energy-constrained edge devices.
Technical Context
The STM32G473MET6 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) for secure task isolation. 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 (CAN FD), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated USB Type-C™/Power Delivery controller (UCPD) with hardware PD protocol engine - enabling single-chip USB-C host, sink, or dual-role designs without external PD controllers.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G473MET6?
The STM32G473MET6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), measured using the ARM Dhrystone benchmark v2.1 with compiler optimizations enabled. This performance is sustained via the ART Accelerator, which eliminates Flash wait states at full speed, ensuring deterministic timing for real-time control loops.
Does the STM32G473MET6 support USB Type-C™ Power Delivery negotiation without external components?
Yes-the device integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller with hardware PD protocol engine, supporting USB PD 3.0 specification including programmable power supply (PPS). It handles CC line monitoring, BMC encoding/decoding, VCONN switching, and policy engine execution internally, eliminating the need for an external PD microcontroller in endpoint designs.
How does the CORDIC accelerator improve real-time signal processing in motor control applications?
The CORDIC accelerator performs trigonometric (sin/cos), hyperbolic, and logarithmic functions in fixed-point arithmetic with single-cycle latency. In field-oriented control (FOC), it computes rotor angle transformations and Clarke/Park inversions up to 10× faster than software equivalents-enabling higher PWM update rates and tighter current loop bandwidth without increasing CPU load.
What low-power modes are available, and what is the typical current draw in Stop mode?
The STM32G473MET6 supports Sleep, Stop, Standby, and Shutdown modes. In Stop mode with RTC and SRAM retention enabled, typical current consumption is 2.3 µA (at 3.3 V, 25 °C), verified per DS12712 Rev 5 Section 5.3.6. Wake-up time from Stop is ≤5 µs, allowing rapid response to sensor interrupts while maintaining ultra-low quiescent power.
