89HPES3T3ZBBCI8

Specialized Overview

The 89HPES3T3ZBBCI8 is a PCI Express switch manufactured by Renesas Electronics, belonging to the 89HPES series. It provides high-performance I/O expansion and switching functions between a PCIe upstream port and two downstream ports or peer-to-peer switching between downstream ports. The device features three PCIe Gen1 lanes and three switch ports. It supports root-to-peripheral (upstream-to-downstream) and peer-to-peer (downstream-to-downstream) data transfers. The architecture includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.
