Introduction

This document is intended for hardware engineers that are willing to integrate the CN9130 SOM from SolidRun ltd, into their own design.

The document provides details with regards CN9130 SOM rev 1.0.

The CN9130 SOM is pin and size compatible to the A388 SOM by SolidRun and can be used as an upgrade for the existing ClearFog Base and ClearFog Pro

Overview

CN9130 System On Module is a highly integrated SOM modulק based on Marvell’s CN9130 SoC.

The SoC highlights are up to 2.2GHz with 4 Cortex A72 Arm cores, DDR4 controller and 6 high speed SERDESs.

The module integrates the following features –

CN9130 SoC (up to 2.2GHz).
On board 64bit DDR4 bus suppoting up to 16GB at 2400MT/s without ECC
Single 12V or 5V DC-input is required.

Simplified Schematics

CN9130 SOM simplified schematics is intended for the following audience –

Software and firmware engineers that enables them to understand the IO and signal connectivity of the SOM design.
Hardware engineers that are willing to use the SOM and build their own development board. This document completes the CN9130 SOM reference manual from description of signal and implementation wise.

Power Consumption

TBD

CN9130 SOM extensions

The CN9130 has two busses of high performance, low latency and low power Marvell® MoChi interfaces (MCi). Each bus is comprised from 4x high speed differential lanes and a dedicated LVDS clock. Both busses are exposed through the SOM connectors and enables to connect 1 or 2 additional 88F8215 comprising the kits of CN9131 and CN9132 on the carrier board.
