STMicroelectronics STM32G484E-EVAL

Overview

STM32G484E-EVAL from STMicroelectronics is an evaluation board built around the STM32G484QET6 Arm® Cortex®-M4 microcontroller featuring 512 KB flash, 96 KB RAM, LQFP128 package, and hardware-accelerated cryptography (AES-256, SHA-256, PKA). It integrates a 240×320 TFT LCD, microSD™ card slot, dual Quad-SPI NOR Flash, SAI audio codec, temperature sensor, and ST-LINK-V3E debugger for embedded firmware development and peripheral validation.

For engineers reviewing the STM32G484E-EVAL datasheet, STM32G484E-EVAL pinout, STM32G484E-EVAL application, or STM32G484E-EVAL equivalent, this board supports rapid prototyping of secure industrial HMI, motor control interfaces, audio-enabled edge nodes, and USB-C-connected IoT gateways with full debug, trace, and power-flexibility capabilities.

Technical Context

The board implements the STM32G484QET6 MCU in LQFP128, enabling simultaneous execution of cryptographic operations and real-time control via its FPU and DSP extensions. It provides direct access to all major peripherals: two CAN 2.0A/B ports, RS-232/RS-485 transceivers, USB Type-C® FS Device, DAC output, comparator/OPAMP test points, and motor-control expansion headers.

ST-LINK-V3E is embedded as a three-in-one interface-mass storage device, Virtual COM port, and SWD/JTAG debugger-with ETM trace support. Power is flexibly supplied via USB VBUS, external source, or adjustable 1.62–3.60 V rail, while onboard current measurement enables precise power profiling.

FAQ

Does STM32G484E-EVAL support USB-C host mode?

No. The board implements USB Type-C® physical connector but only in USB Full-Speed Device mode, not host or OTG. It enumerates as a Virtual COM port, mass storage device, or debug interface via ST-LINK-V3E - all dependent on target MCU firmware configuration, not host capability.

Can the onboard ST-LINK-V3E program third-party STM32G4 chips?

Yes. ST-LINK-V3E supports programming and debugging of all STM32G4-series MCUs via SWD or JTAG, including external targets connected through the 10-pin STDC14 or Arm® Cortex® 10-pin debug headers. No additional license or firmware update is required.

What is the purpose of the two Quad-SPI NOR Flash memories?

They provide parallel, high-speed non-volatile storage for dual-bank firmware updates, secure boot image storage, or offloading data logging from internal flash. Each 512-Mbit device connects via dedicated Quad-SPI peripheral with memory-mapped mode support for zero-wait-state execution.

Is the LQFP128 footprint on the board accessible for custom MCU replacement?

No. The STM32G484QET6 is soldered directly onto the PCB and not socketed. The board is designed for evaluation-not field-replaceable MCU upgrades. All MCU I/Os are exposed via extension headers, but the IC itself is permanently mounted for thermal and signal integrity compliance.
