Microchip KSZ9567STXI

以太网开关I²C，SPI1.8V，2.5V，3.3V

Overview

The KSZ9567STXI is a fully integrated layer 2, managed,seven-port gigabit Ethernet switch with numerousadvanced features. Five of the seven ports incorporate10/100/1000 Mbps PHYs. The other two ports haveinterfaces that can be configured as SGMII, RGMII, MII or RMII.Either of these may connect directly to a host processor orto an external PHY.  The SGMII port may interface to a fiber optic transceiver.

I/O pin strapping facility to set certain register bits from I/O pins at reset time
