STMicroelectronics STM32G474VCT6

Overview

STM32G474VCT6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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 5×12-bit ADCs (0.25 µs), 7×12-bit DACs, 6 operational amplifiers, and a 184 ps resolution HRTIM for precision motor control in industrial inverters.

For engineers reviewing the STM32G474VCT6 datasheet, STM32G474VCT6 pinout, STM32G474VCT6 application, or STM32G474VCT6 equivalent, key selection criteria include its dual-bank read-while-write Flash, CORDIC/FMAC math accelerators, FDCAN FD support, 5 V-tolerant I/Os, and LQFP100 package compatibility with high-pin-count analog/motor control designs.

Technical Context

The device implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash memory, and integrates two hardware math accelerators: CORDIC for trigonometric computation and FMAC for digital filter operations. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals without bus contention.

It features three FDCAN controllers compliant with ISO 11898-1:2015 (FD mode), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated UCPD controller for USB Type-C™ power delivery negotiation - all synchronized via a multi-source clock system with PLL, 4–48 MHz external crystal, and calibrated 32 kHz RTC oscillator.

FAQ

What is the maximum operating temperature range for STM32G474VCT6?

The STM32G474VCT6 is qualified for industrial operation from -40°C to +105°C ambient temperature, validated per AEC-Q100 stress test conditions for reliability in harsh environments such as motor drive enclosures and solar inverter housings.

Does STM32G474VCT6 support hardware encryption or secure boot?

While it lacks dedicated cryptographic accelerators (AES/SHA), STM32G474VCT6 provides PCROP (proprietary code readout protection), securable memory areas, and 1 KB one-time-programmable memory for key storage - enabling secure boot implementation via software libraries and trusted execution environment partitioning.

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

Yes - the HRTIM includes dedicated dead-time insertion units per channel pair, supporting independent rising/falling edge delay programming down to 184 ps resolution, plus emergency shutdown inputs for hardware-level fault response in motor gate drivers.

Is external memory interface (FSMC) available on the LQFP100 package?

Yes - all 100 pins of the LQFP100 package expose the full FSMC bus (NOR/NAND/PSRAM), including address/data multiplexing, bank controls, and wait-state signaling, enabling direct connection to external SDRAM or flash without glue logic.
