Product overview

Key Benefits

Support for the NeoChrom VG GPU

New processing unit optimizes rendering of vector graphics and animations such as flips, spins, scaling and more, vastly increasing the number of frames per second - fully integrated in X-CUBE-TOUCHGFX.


The STM32U5G9J-DK2 Discovery kit is a complete demonstration and development platform for the STM32U5G9ZJT6Q microcontroller, featuring an Arm® Cortex®‑M33 core with Arm® TrustZone®.

Leveraging the innovative ultra-low power-oriented features, 3 Mbytes of embedded SRAM, 4 Mbytes of embedded flash memory, and rich graphics features, the STM32U5G9J-DK2 Discovery kit enables users to prototype applications with state-of-the-art energy efficiency, as well as providing stunning and optimized graphics rendering with the support of a 2.5D Neo-Chrom accelerator, Chrom-ART Accelerator, and Chrom-GRC™ MMU.

The STM32U5G9J-DK2 Discovery kit integrates a full range of hardware features that help the user evaluate all the peripherals, such as a 5" RGB 800x480 pixels TFT colored LCD module with a 24‑bit RGB interface and capacitive touch panel, USB Type-C® HS, Octo‑SPI flash memory device, ARDUINO®, and STLINK-V3EC (USART console).

The STM32U5G9J-DK2 Discovery kit integrates an STLINK-V3EC embedded in-circuit debugger and programmer for the STM32 microcontroller with a USB Virtual COM port bridge and comes with the STM32CubeU5 MCU Package, which provides an STM32 comprehensive software HAL library as well as various software examples.
