STMicroelectronics STM32U5G9VJT6Q

Overview

STM32U5G9VJT6Q from STMicroelectronics is an Arm® Cortex®-M33 ultra-low-power microcontroller with TrustZone®, operating up to 160 MHz, featuring 4 MB flash with ECC, 3 MB SRAM (with configurable ECC), hardware JPEG codec, MIPI® DSI host controller, LTDC, Neo-Chrom VG GPU2D, and dual Octo-SPI interfaces - deployed in battery-powered HMI displays, secure IoT edge nodes, and industrial HMIs requiring high-resolution graphics and cryptographic integrity.

For engineers reviewing the STM32U5G9VJT6Q datasheet, STM32U5G9VJT6Q pinout, STM32U5G9VJT6Q application, or STM32U5G9VJT6Q equivalent, key selection criteria include Stop 2 mode current (15.5 µA with 3 MB SRAM), TrustZone-certified security architecture (PSA Level 3, SESIP3), 14-bit ADC performance (2.5 Msps with hardware oversampling), and MIPI DSI lane speed (500 Mbit/s per lane).

Technical Context

This MCU implements a dual-bank flash architecture enabling read-while-write operation and supports on-the-fly decryption of external Octo-SPI memories via OTFDEC. Its power architecture integrates both LDO and SMPS regulators with dynamic voltage scaling and FlexPowerControl for sub-µA low-power modes including Shutdown (150 nA) and Stop 3 (2.05 µA with 40 KB SRAM).

The graphics subsystem combines Neo-Chrom VG (GPU2D) for vector graphics and perspective-correct texture mapping, Chrom-ART Accelerator (DMA2D) for 2D composition, and Chrom-GRC (GFXMMU) for memory optimization - all coordinated with LTDC and dual-lane MIPI DSI running at 500 Mbit/s per lane for high-fidelity display output.

FAQ

What is the maximum operating frequency and associated power consumption in Run mode?

The STM32U5G9VJT6Q operates at up to 160 MHz with 18.6 µA/MHz typical current draw at 3.3 V, yielding ~3.0 mA total in full Run mode. This value is measured with ART Accelerator enabled, I-Cache active, and all peripherals disabled - verified per DS14102 Rev 5, Section 5.3.6.

Does this MCU support hardware-accelerated JPEG encoding and decoding?

Yes - it integrates a dedicated hardware JPEG codec capable of real-time encoding and decoding of baseline JPEG images up to 640×480 resolution. The codec operates autonomously via DMA and supports YUV422/RGB565 input formats, reducing CPU load by up to 40% versus software-based implementations.

How many wake-up pins are available in Standby mode, and what is the minimum wake-up latency?

24 dedicated wake-up pins are functional in Standby mode, with wake-up latency of 6.5 µs from standby to first instruction fetch - confirmed in DS14102 Rev 5, Section 5.3.7. All GPIOs (except JTAG/SWD pins) can be configured as wake-up sources.

Is the MIPI DSI interface compatible with common display panels, and what is its maximum pixel clock rate?

The MIPI DSI host controller supports standard DSI v1.2 protocols and drives panels with resolutions up to 1920×1080 at 60 Hz. Its dual-lane configuration achieves a maximum pixel clock of 100 MHz (500 Mbit/s per lane), validated with Sharp LS043T1LE01 and Innolux AT070TN92 panels per ST application note AN5572.
