Product details

Overview

STM32G474VCT3TR 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, 96 KB SRAM (32 KB with hardware parity), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six operational amplifiers, and a high-resolution timer (HRTIM) with 184 ps resolution - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G474VCT3TR datasheet, STM32G474VCT3TR pinout, STM32G474VCT3TR application, or STM32G474VCT3TR equivalent, key selection criteria include HRTIM timing precision for PWM-based power stages, CORDIC/FMAC acceleration for real-time control math, dual-bank Flash with PCROP for secure firmware updates, and FDCAN support for automotive-grade communication.

Technical Context

The STM32G474VCT3TR implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and DSP instruction set for deterministic real-time control. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses to sustain concurrent analog acquisition, timer-triggered PWM generation, and communication stack processing.

It integrates three FDCAN controllers supporting flexible data-rate (CAN FD), USB 2.0 full-speed with LPM/BCD, and UCPD for USB Type-C™ power delivery negotiation - all synchronized via a multi-source clock system including 4–48 MHz crystal oscillator, 32 kHz RTC calibratable oscillator, and ±1% internal 16 MHz RC with PLL.

Use Scenario: Isolated AC/DC and DC/DC converters with adaptive voltage regulation and protection sequencing.

IC Role / Device Role / Timing Role: Digital power controller managing PWM generation, voltage/current loop compensation, fault detection, and PMBus communication.

Use Value: CORDIC computes sine/cosine for space-vector modulation; FMAC implements 2nd-order digital compensators with <1 µs latency per iteration.

Battery Management System (BMS)

Industrial Sensor Hub

Use Scenario: Cell monitoring, balancing, and safety management in 12–24S Li-ion packs for energy storage and e-mobility.

IC Role / Device Role / Timing Role: Central BMS MCU acquiring cell voltages/temperatures via integrated ADCs, running SOC/SOH algorithms, and communicating via FDCAN to master controller.

Use Value: Five independent 12-bit ADCs sample up to 42 channels simultaneously with 0.25 µs conversion - supports full-stack monitoring in <10 ms.

Use Scenario: Multi-sensor aggregation (temperature, pressure, vibration) with edge preprocessing and wireless gateway interface.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance mixed-signal microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32G474RET6	LQFP64 package (64-pin), 512 KB Flash, 96 KB SRAM - same core/peripherals but fewer GPIOs and no UCPD or SAI.	Suitable for cost-constrained motor drives where USB-C PD and audio interfaces are unnecessary.	Select when board space and BOM count are prioritized over USB-C power negotiation and advanced analog channel density.
STM32H743VIT6	Cortex-M7 core (480 MHz), 2 MB Flash, 1 MB SRAM, dual-core option, no HRTIM - adds DSI, Ethernet, and crypto accelerators.	Targeted at high-throughput HMI, vision, or gateway applications requiring Linux-capable performance, not ultra-precise PWM timing.	Choose only if application demands >200 MHz CPU throughput or peripheral sets beyond G4 scope - not a drop-in replacement for HRTIM-dependent designs.

Compared with STM32G474VCT3TR, the STM32G474RET6 trades pin count and UCPD capability for compactness, while the STM32H743VIT6 shifts focus from nanosecond-precision timing to raw compute and connectivity - making the G474VCT3TR uniquely balanced for digital power and motor control where HRTIM and analog integration are non-negotiable.

FAQ

What is the maximum operating frequency and associated performance metric of the STM32G474VCT3TR?

The STM32G474VCT3TR operates at up to 170 MHz with 213 DMIPS (Dhrystone MIPS) performance, achieved using the ART Accelerator for zero-wait-state Flash execution and the Cortex-M4 core with FPU and DSP extensions. This enables deterministic real-time response in control loops with sub-microsecond ISR latency.

Does the STM32G474VCT3TR support hardware encryption or secure boot features?

While it lacks dedicated cryptographic accelerators (AES/RSA), the STM32G474VCT3TR provides secure firmware update capability via proprietary code readout protection (PCROP), securable memory areas, and 1 KB one-time-programmable (OTP) memory for keys or certificates - meeting IEC 62443-3-3 SL2 requirements for basic secure boot implementation.

How many analog-to-digital converter (ADC) channels does the STM32G474VCT3TR support, and what is their effective resolution?

The device integrates five independent 12-bit ADCs supporting up to 42 total channels, with hardware oversampling enabling up to 16-bit effective resolution. Conversion time is 0.25 µs at 12-bit, and the ADCs support simultaneous sampling triggered by HRTIM or timers - essential for three-phase current reconstruction in motor control.

Is the STM32G474VCT3TR pin-compatible with other members of the STM32G4 family?

No - the STM32G474VCT3TR uses the LQFP100 package, whereas other G474 variants (e.g., G474CB, G474RE) use LQFP48, LQFP64, or WLCSP packages. Pin mapping differs significantly across packages; migration requires PCB redesign and signal reassignment, though firmware is largely compatible within the same G474 subfamily.
