VisionSOM-RT-ETH Datasheet and Pinout

---

General description

The VisionSOM-RT-ETH family is a SODIMM-sized SoM based on the NXP i.MX RT application processor which features an advanced implementation of a single ARM Cortex-M7 core (at speeds up to 600MHz).

The VisionSOM-RT-ETH is a low power highly integrated SoM (System-on-Module) featuring Ethernet PHY on-board, high computation performance, real-time functionality and MCU usability. High security enabled by AES-128, HAB and On-the-fly QSPI Flash Decryption together with 2D graphical acceleration make an ideally suited solution for home and industrial control systems, wireless application, communication solutions and real-time systems.

The system supports industrial grade targeting embedded application.

SoMLabs also provides a complete hardware and software development board for the SoM in the form of a carrier board and optional TFT display and touch panel.

Notes:
1. Excluding external load connected to +3.3VOUT lines and with Ethernet PHY in stand-by mode.
2. Applying the maximum voltage 3.6V results in shorten lifetime. Recommended value is smaller than 3.5V.

Pinout

Important notes:
1. LCD_DATAxx pins can be used for boot sequence configuration. In such case we recommend to use LCD_DATAxx lines as outputs or using eFuse boot configuration. Currently produced modules are configured using eFuse and LCD_DATAxx pins can be used without restrictions.
2. Internal peripherals and pin functions depends on i.MX-RT version (i.a. in RT1052 there is just one Ethernet channel). Description in table fits to RT1052 MCU.
3. The VisionSOM-RT-ETH module is equipped with hardware system watchdog that is controlled by GPIO_AD_B1_10 line (pin L13).
