STMicroelectronics STM32G484QET6

Overview

STM32G484QET6 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 parity + 32 KB CCM SRAM), 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 STM32G484QET6 datasheet, STM32G484QET6 pinout, STM32G484QET6 application, or STM32G484QET6 equivalent, key selection criteria include HRTIM timing precision for PWM generation, dual-bank Flash read-while-write capability for firmware updates, hardware math accelerators (CORDIC/FMAC), FDCAN FD support for automotive/industrial networks, and UCPD interface for USB Type-C™ power delivery control.

Technical Context

The STM32G484QET6 implements an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash memory at 170 MHz. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals via multiple AHB/APB buses, ensuring deterministic latency for time-critical control loops.

It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), supporting flexible data-rate up to 5 Mbit/s, alongside a dedicated USB Type-C™/USB Power Delivery controller (UCPD) with VBUS monitoring, CC line control, and PD protocol engine - enabling single-chip USB-C port management without external PHY.

FAQ

What is the maximum operating temperature range for STM32G484QET6?

The STM32G484QET6 is qualified for industrial temperature range: –40°C to +85°C ambient. It features internal temperature sensor calibration data stored in system memory and supports thermal shutdown via programmable voltage detector (PVD) thresholds - enabling robust operation in enclosed enclosures or high-ambient environments like factory floors.

Does STM32G484QET6 support hardware cryptographic acceleration beyond AES?

Yes - in addition to AES-128/256, the STM32G484QET6 includes a true random number generator (RNG) compliant with NIST SP800-90B and a CRC calculation unit supporting multiple polynomials (CRC-32, CRC-16, etc.). It does not integrate SHA or RSA accelerators; those functions require software implementation or external co-processors.

Can the HRTIM module generate complementary PWM outputs with programmable dead time?

Yes - the HRTIM includes dedicated dead-time insertion logic per output channel, configurable down to 184 ps resolution. It supports emergency stop inputs, fault protection blanking, and synchronous update of duty cycle and dead time across all six timers - essential for half-bridge and three-phase inverter gate driving with SiC/GaN devices.

Is the UCPD peripheral capable of full USB Power Delivery 3.0 compliance?

Yes - the integrated UCPD controller implements the complete USB PD 3.0 physical layer (PHY) and protocol engine, including BMC encoding/decoding, VBUS monitoring, CC line state machine, VCONN sourcing, and PD message parsing - certified per USB-IF compliance test plan Rev 2.0, eliminating need for external PD controllers like the FUSB302.
