STMicroelectronics STM32G474VET6TR

Overview

STM32G474VET6TR 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, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including six operational amplifiers, seven 12-bit DACs, five 12-bit ADCs (0.25 µs conversion), and a 184 ps resolution HRTIM - deployed in industrial motor control, digital power supplies, and precision sensor signal conditioning.

For engineers reviewing the STM32G474VET6TR datasheet, STM32G474VET6TR pinout, STM32G474VET6TR application, or STM32G474VET6TR equivalent, key selection criteria include HRTIM timing resolution for PWM dead-time control, dual-bank Flash with PCROP for secure firmware updates, CORDIC/FMAC acceleration for real-time math, and 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

This MCU implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz, alongside a Memory Protection Unit (MPU) and securable memory regions including 1 KB OTP and PCROP. Its interconnect matrix supports concurrent high-bandwidth peripheral access without arbitration bottlenecks.

The analog subsystem integrates three buffered 1 MSPS DAC outputs, four unbuffered 15 MSPS internal DACs, six rail-to-rail op-amps configurable in PGA mode, and a dedicated voltage reference buffer (VREFBUF) with selectable 2.048 V / 2.5 V / 2.9 V outputs - all calibrated and specified across the full −40 °C to +85 °C industrial temperature range.

FAQ

What is the maximum operating temperature range for STM32G474VET6TR?

The STM32G474VET6TR is qualified for industrial temperature operation from −40 °C to +85 °C. All electrical characteristics - including ADC/DAC accuracy, timer resolution, and Flash write endurance - are guaranteed across this full range per ST's DS12288 Rev 6 specification.

Does STM32G474VET6TR support secure firmware updates?

Yes. It features dual-bank Flash with read-while-write capability, Proprietary Code Read-Out Protection (PCROP), and a securable memory area. These allow atomic firmware swaps and protection against unauthorized code extraction - essential for certified industrial and medical devices.

Can the HRTIM generate complementary PWM signals with programmable dead time?

Yes. The HRTIM provides 12 independent PWM outputs with hardware-configurable dead-time insertion (down to 184 ps steps), fault input mapping for emergency shutdown, and synchronization across all 6 timers - enabling robust gate driving for 3-phase inverters.

Is the USB interface compatible with USB Battery Charging (BC) 1.2 specification?

Yes. The integrated USB 2.0 full-speed interface supports USB Battery Charging (BC) 1.2 detection, including SDP/CDP/DCP enumeration, enabling automatic charger type identification and optimal current draw in portable power applications.
