Introduction

This document is intended for hardware engineers that are willing to integrate CN913x COM express type 7 module from SolidRun ltd.

The document provides details with regards CN913x module rev 1.1.

Overview

CN9132 COM Express type 7 is a highly integrated COM modules based on Marvell’s CN913x SoC.
The SoC highlights are up to 2.2GHz with 4 Cortex A72 Arm cores, DDR4 controller and 18 high speed SERDESs.

The module integrates the following features –

CN9130 SoC (up to 2.2GHz).
SO-DIMM DDR4 connected to the DDR controller. The SO-DIMM supports up to 16GByte SO-DIMM DDR4 2400Mtps memory with and without ECC, registered or non-registered.
Single 12V DC-input is required.

Simplified Schematics

CN9130 COM express type 7 simplified schematics is intended for the following audience –

Software and firmware engineers that enables them to understand the IO and signal connectivity of the COM express design.
Hardware engineers that are willing to use the COM express and build their own development board. This document completes the CEx7 CN9130 reference manual from description of signal and implementation wise.

Power Consumption

TBD

High Speed port configuration

The CN9130 Com Express Type 7 family includes 3 variations:

CN9130 is comprised from a single CN9130.
CN9131 is comprised from a single CN9130 with one additional 88F8215. This includes a CP with 6 shared high speed SERDES interfaces, for a total of 12 lanes.
CN9132 is comprised from a single CN9130 with two additional 88F8215. Each one of them has a CP with 6 shared high speed SERDES interfaces, for a total of 18 lanes.

Common Questions and Answers

Q: Are the I2C signals 3.3v?

A: Per the COM express specifications, all GPIO and control signals are in the 3.3v domain. Please refer to the AB and CD header description on the pull-up values of those signals.

Q: Can the SERDES lanes be configured differently than the COM express standard?

A: Yes.
