Product details
Overview
STM32G473VEH3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, 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 three FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473VEH3 datasheet, STM32G473VEH3 pinout, STM32G473VEH3 application, or STM32G473VEH3 equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, hardware math accelerators (CORDIC and FMAC), 5 V-tolerant I/Os (up to 107), UCPD interface for USB Type-C™ PD, and support for ultra-low-power stop/standby modes with RTC wakeup.
Technical Context
The STM32G473VEH3 implements an Arm Cortex-M4 core with floating-point unit and Memory Protection Unit (MPU), coupled with ST's Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals via multiple AHB/APB buses.
It integrates dedicated hardware accelerators: CORDIC for real-time trigonometric computation and FMAC for FIR/IIR filter execution - both accessible via DMA and tightly coupled to the CPU pipeline. Analog subsystem includes rail-to-rail comparators, programmable-gain op-amps with external terminal access, and VREFBUF with selectable 2.048 V / 2.5 V / 2.9 V outputs.
