STMicroelectronics STM32U5G7VJT6Q

Overview

STM32U5G7VJT6Q from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 microcontroller with TrustZone®, 4 MB flash, 3 MB SRAM, hardware JPEG codec, MIPI® DSI, LTDC, and Neo-Chrom GPU2D - designed for secure, graphics-rich IoT edge devices operating at up to 160 MHz with 18.6 μA/MHz active power efficiency.

For engineers reviewing the STM32U5G7VJT6Q datasheet, STM32U5G7VJT6Q pinout, STM32U5G7VJT6Q application, or STM32U5G7VJT6Q equivalent, key selection criteria include TrustZone-certified security architecture, LPBAM-enabled autonomous peripheral operation in Stop 2 mode, dual Octo-SPI interfaces for encrypted external memory, and integrated 2D graphics acceleration for battery-powered HMI displays.

Technical Context

The device integrates a dual-bank ECC-protected 4-MB flash with read-while-write capability and configurable SRAM partitioning (up to 3026 KB with ECC off), enabling secure over-the-air firmware updates and real-time data buffering. Its FlexPowerControl architecture supports five low-power modes - including 150 nA Shutdown and 480 nA Standby with RTC - managed via embedded SMPS and LDO regulators with dynamic voltage scaling.

Graphics subsystem comprises Neo-Chrom VG (GPU2D) for rotation/scaling, Chrom-ART DMA2D for bitmap composition, and Chrom-GRC (GFXMMU) for memory optimization - all synchronized with MIPI® DSI (500 Mbit/s per lane) and LTDC controller to drive high-resolution TFT panels without CPU load.

FAQ

What is the maximum operating frequency and associated power consumption of STM32U5G7VJT6Q?

The device operates at up to 160 MHz with 18.6 μA/MHz active current at 3.3 V (measured per DS14102 Rev 5, Section 5.3.6). This efficiency is achieved via ART Accelerator with 32-KB instruction cache enabling zero-wait-state execution from flash, and dynamic voltage scaling between SMPS and LDO regulators.

Does STM32U5G7VJT6Q support hardware-accelerated JPEG encoding or only decoding?

STM32U5G7VJT6Q integrates a full hardware JPEG codec supporting both encoding and decoding of baseline JPEG streams, as confirmed in DS14102 Rev 5 Section 3.22 and Table 34. It processes YUV422/RGB565 input at up to 30 fps for 1024×768 frames, offloading CPU-intensive compression from firmware.

How many wake-up pins are available in Shutdown mode, and what is their electrical behavior?

The device provides 24 dedicated wake-up pins in Shutdown mode (150 nA), each configurable as edge-sensitive inputs with internal pull-up/pull-down resistors (Section 5.3.7). These pins retain state during shutdown and trigger reset or wake-up interrupt without external circuitry, supporting button, tamper, or sensor event detection.

Can the MIPI DSI interface drive dual displays simultaneously, and what is the maximum supported resolution?

STM32U5G7VJT6Q's single MIPI DSI host controller supports one DSI link with two data lanes (DSI_D0, DSI_D1) and one clock lane, driving one display at up to QXGA (2048×1536) @ 60 Hz. Dual-display operation requires external DSI splitter ICs or time-multiplexed panel switching - no native dual-link or dual-display controller is integrated.
