STMicroelectronics STM32U5G7VJT6

Overview

STM32U5G7VJT6 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 in 1.71–3.6 V supply range.

For engineers reviewing the STM32U5G7VJT6 datasheet, STM32U5G7VJT6 pinout, STM32U5G7VJT6 application, or STM32U5G7VJT6 equivalent, key selection considerations include LPBAM-enabled autonomous peripheral operation in Stop 2 mode, 15.5 μA Stop 2 current with full 3-MB SRAM retention, PSA Level 3/SESIP3 security certification, and dual Octo-SPI interfaces supporting on-the-fly external memory decryption.

Technical Context

The STM32U5G7VJT6 integrates a dual-bank 4-MB flash with ECC and read-while-write capability, plus configurable SRAM (2962 KB with ECC enabled), enabling secure firmware updates and real-time code/data separation. Its FlexPowerControl architecture supports five low-power modes - including 195 nA Standby and 2.05 μA Stop 3 with 40-KB SRAM - managed via embedded LDO and SMPS with dynamic voltage scaling.

Graphics acceleration is implemented through three dedicated IP blocks: Neo-Chrom VG (GPU2D) for vector rendering and perspective-correct texture mapping, Chrom-ART DMA2D for bitmap composition, and Chrom-GRC (GFXMMU) for memory-efficient resource allocation - all coordinated via the LTDC and dual-lane MIPI DSI host controller running at 500 Mbit/s per lane.

FAQ

What is the maximum operating frequency and supported voltage range for STM32U5G7VJT6?

The STM32U5G7VJT6 operates at up to 160 MHz using its Arm Cortex-M33 core. It supports a single-supply voltage range of 1.71 V to 3.6 V across VDD, with separate VDDA (analog) and VDDIO2 (I/O) rails allowing mixed-voltage operation down to 1.08 V for select pins. This range enables direct interfacing with diverse sensors and peripherals while maintaining ultra-low-power operation.

Does STM32U5G7VJT6 support hardware-accelerated graphics rendering?

Yes - it integrates three complementary graphics accelerators: Neo-Chrom VG (GPU2D) for vector graphics and texture mapping, Chrom-ART (DMA2D) for bitmap composition, and Chrom-GRC (GFXMMU) for memory optimization. These work with the LTDC and dual-lane MIPI DSI controller to drive high-resolution displays with minimal CPU load and deterministic frame timing.

How does the security architecture of STM32U5G7VJT6 meet industrial certification requirements?

The device is certified to PSA Level 3 and SESIP3 Assurance Target standards. It implements Arm TrustZone for hardware-enforced secure/non-secure world separation, includes a Root Secure Services (RSS) engine for secure boot, supports on-the-fly external memory decryption (OTFDEC), and provides DPA-resistant AES/PKA accelerators - fulfilling requirements for secure firmware installation, runtime integrity, and cryptographic key protection in industrial deployments.

What low-power modes are available and what is the lowest achievable current draw?

Five low-power modes are supported: Shutdown (150 nA), Standby (195 nA), Standby with RTC (480 nA), Stop 3 (2.05 μA with 40-KB SRAM), and Stop 2 (15.5 μA with full 3-MB SRAM). All retain critical state and support 24 wake-up pins. The 150 nA Shutdown mode disables all clocks and regulators except VBAT domain - ideal for long-term storage or emergency wake-on-event scenarios.
