ST UM2967

Introduction
The STM32U5A9J-DK Discovery kit is a complete demonstration and development platform for the STM32U5A9NJH6Q
microcontroller, featuring an Arm
®
Cortex
®
‑M33 core with Arm
®
TrustZone
®
.
Leveraging the innovative ultra-low‑power oriented features, 2.5 Mbytes of embedded SRAM, 4 Mbytes of embedded flash
memory, and rich graphics features, the STM32U5A9J-DK Discovery kit enables users to easily prototype applications with
state-of-the-art energy efficiency, as well as providing stunning and optimized graphics rendering with the support of the 2.5D
NeoChrom Accelerator, Chrom-ART Accelerator, and Chrom-GRC
™
MMU.
The full range of hardware features available on the board helps users to enhance their application development by an
evaluation of all the peripherals such as a 2.47‑inch RGB 480×480 pixels TFT round LCD module with MIPI DSI
®
interface and
capacitive touch panel, USB Type-C
®
HS, Octo‑SPI flash memory device, Hexadeca‑SPI PSRAM memory device, eMMC flash
memory device, Time-of-Flight and gesture detection sensor, temperature sensor, and two 2.54 mm pitch double-row flexible
expansion connectors for easy prototyping with daughterboards for specific applications (USART, LPUART, two SPIs, SAI,
three I
2
C, SDMMC, ADCs, timers, and GPIOs).
The STM32U5A9J-DK Discovery kit integrates an STLINK-V3E 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.
