STMicroelectronics STM32G474VET6

Overview

STM32G474VET6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 96 KB SRAM (including 32 KB CCM with parity), and integrated HRTIM with 184 ps resolution for precision motor control. It integrates CORDIC and FMAC hardware accelerators, dual-bank read-while-write Flash, and supports USB Full-Speed, FDCAN, and UCPD for USB Type-C™ power delivery.

For engineers reviewing the STM32G474VET6 datasheet, STM32G474VET6 pinout, STM32G474VET6 application, or STM32G474VET6 equivalent, key selection criteria include HRTIM timing resolution, analog subsystem density (5× ADCs, 7× DACs, 6× op-amps), Flash ECC and PCROP security features, and FDCAN/Flexible Data Rate support for automotive and industrial networking.

Technical Context

The STM32G474VET6 implements a tightly coupled ART Accelerator enabling zero-wait-state execution from Flash at 170 MHz, paired with a Memory Protection Unit (MPU) and securable memory areas including PCROP and 1 KB OTP. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses for concurrent peripheral access without contention.

Its analog subsystem combines seven 12-bit DACs (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), five 12-bit ADCs (0.25 µs conversion, up to 42 channels, 16-bit oversampling), six rail-to-rail op-amps configurable in PGA mode, and a programmable VREFBUF (2.048 V / 2.5 V / 2.9 V).

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32G474VET6 achieves 170 MHz maximum CPU frequency using its Adaptive Real-Time Accelerator (ART Accelerator), which provides zero-wait-state execution from Flash memory. This eliminates instruction fetch bottlenecks, enabling sustained 213 DMIPS performance without external RAM or cache reliance-verified across temperature and voltage ranges per DS12288 Rev 6 Section 5.3.1.

Does STM32G474VET6 support USB Power Delivery natively?

Yes-it integrates a full USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. The on-die UCPD block handles CC line detection, BMC decoding/encoding, VCONN switching, VBUS discharge, and policy engine execution without external ICs, as confirmed in Section 3.35 and Table 2 of DS12288 Rev 6.

How many independent ADCs does it have, and what is their simultaneous sampling capability?

The device integrates five independent 12-bit ADCs, each with up to 16-channel input multiplexing. All five support hardware-synchronized start triggers, enabling true simultaneous sampling across ≥20 analog inputs-critical for FOC motor control and multi-sensor acquisition, as detailed in Sections 3.18 and Table 2 of the datasheet.

Is the HRTIM module capable of generating complementary PWM with programmable dead time?

Yes-the HRTIM includes six 16-bit timers with dedicated dead-time insertion units and emergency stop inputs. Each timer supports complementary PWM pairs with fully programmable dead time down to 184 ps resolution, validated in electrical characteristics Section 5.3.16 and functional overview Section 3.24.1 of DS12288 Rev 6.
