The 89EBPES12T3G2 Evaluation Board (also referred to as EB12T3G2) provides an evaluation platform for the PES12T3G2 switch. It is also a cost effective way to add a PCIe downstream port (x4) to an existing system with a limited number of PCIe downstream ports. The EB12T3G2 eval board is designed to function as an add-on card to be plugged into a x4 PCIe slot available on a motherboard hosting an appropriate root complex, microprocessor(s), and two downstream ports. The EB12T3G2 is a vehicle to test and evaluate the functionality of the PES12T3G2 chip. Customers can use this board to get a headstart on software development prior to the arrival of their own hardware. The EB12T3G2 is also used by Renesas to reproduce system-level hardware or software issues reported by customers.
