KSZ8895MQ is one of KSZ8895 family. KSZ8895MQ contains two MII interfaces for MAC 5 and PHY 5 of the port 5. KSZ8895RQ is one of KSZ8895 family. KSZ8895RQ contains two RMII interfaces for MAC 5 and PHY 5 of port 5. The device had been designed with cost sensitive systems in mind but still offers a multitude of features such as switch management;...
KSZ8895 Evaluation Board User’s Guide 4.0 Hardware Description The KSZ8895 evaluation board is in a compact form factor and can sit on a bench near a computer with USB connector. There are four options for configuration: strap in mode; EEPROM mode, SMI mode and SPI mode.
Strap in configuration mode is the quickest and easiest way to get started. In this mode, the KSZ8895 acts as a stand-alone 5 port switch. The user has to simply set the board’s configuration jumpers to the desired settings and apply power to the board. The user can also change jumper settings while power is applied to the board and press the convenient manual reset button for the new settings to take effect.
4.1.1 Feature Setting Jumpers The evaluation board provides jumpers to allow the user to easily set strap in configurations for the KSZ8895. Table 1 describes the jumpers and their function in the open or closed state. Table 1 Feature Setting Jumpers...
The evaluation board has an EEPROM to allow the user to explore more extensive capabilities of the KSZ8895. The user can conveniently program the EEPROM on board using the USB port from any computer with a WIN 2000/XP environment and the Micrel provided software. This makes it easy for the user to evaluate features like “broadcast storm protection”...
KSZ8895 Evaluation Board User’s Guide 4.3 SPI Mode From SPI interface to the KSZ8895, use a USB to SPI converter that allows accessing all of the KSZ8895 features and registers. The user can easily access the SPI interface using a computer connected to the evaluation board’s USB port interface.
KSZ8895, and we refer to it as the port 5 Switch SW5-MII/RMII port. The second MII port connects to the fifth PHY in the KSZ8895. We refer to this as the PHY5 P5-MII/RMII port. Both the Switch MII/RMII port and the PHY5 MII/RMII port configuration are set on the board by using the MII Enable bit (register 2, bit 3) in conjunction with JP10 and JP11 as shown in Table 6.
KSZ8895 Evaluation Board User’s Guide This mode is usually used to connect the KSZ8895 to a CPU with MAC. In MAC mode, the Switch MII/RMII port will transmit and receive signals on J7 of the board’s female MII connector. This interface is normally used to connect the KS8895 to an external PHY.

5 VDC power source from the USB port when JP47 pin 2-3 is closed. 10. The KSZ8895 will power up initial default configuration with the start switch in register 1 bit 0 = ‘0’ which means the switch is “off”. You can set the bit 0 =’1’ to start switch in SMI mode.
3. In folder of Window SPI_I2C_MIIM Tools, there is a MicrelSwitchPhyTools_1.xx.msi file which is clicked to create two application files in the default folder of Micrel (or you selected folder) and two icons on desktop, they need window drivers supported first, see 5.2 section for detail.
