Overview

Description

The 89EBPES4T4 Evaluation Board (also referred to as EB4T4) provides an evaluation platform for the PES4T4 switch and the PES3T3 switch. It is also a cost effective way to add a PCIe downstream port (x1) to an existing system with a limited number of PCIe downstream ports. The EB4T4 evaluation board is designed to function as an add-on card to be plugged into a x1 PCIe slot available on a motherboard hosting an appropriate root complex, microprocessor(s), and three downstream ports. The EB4T4 is a vehicle to test and evaluate the functionality of the PES4T4 chip. Customers can use this board to get a head start on software development prior to the arrival of their own hardware. The EB4T4 is also used by Renesas to reproduce system-level hardware or software issues reported by customers.
