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 mode configuration is easily done with on board jumper options.
EEPROM mode, SMI mode and SPI mode are accomplished through a built in USB port interface.
Using Micrel EEPROM software and your PC, you can program the EEPROM on board by the
USB port. Using Micrel SPI software and your PC, you can access the KSZ8895’s full feature set
registers by the USB to SPI interface. Or using Micrel MDC/MDIO software and SMI software
with your PC, you can access the KSZ8895’s MIIM PHY registers by generic MDC/MDIO
interface and full feature set registers by the SMI mode of MDC/MDIO interface. The board also
features the MII connectors for the Switch MII/RMII interface. These are to facilitate connections
from the switch to an external MAC or PHY. There is also an additional MII connector for the
PHY5 MII/RMII interface to an external MAC. This is used to recover use of the fifth PHY unit in
broadband gateway applications or others.
The KSZ8895 evaluation board is easy to use. There are programmable LED indicators for link and
activity on all ports and a power LED. A manual reset button allows the user to reset the board
without removing the power plug. A standard 5VDC power supply can be used by the power jack so
that the user can supply power from any 110-240 Volt AC wall or bench socket, and the power also
can be provided by USB port when close pin 2-3 of the JP47 jumper.

4.1 Strap in 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. Note that even if there is no external strap in values are set, internal pull
up and pull down resistors will set the KSZ8895 default configuration. Section 4.1.1 covers each
jumper on the board and describes its function.
To start in strap in configuration mode, make sure that JP1 and JP2 are closed and JP3, JP4, JP8 and
JP9 are open. In this mode, pins (PS1,PS0)=(0,0), the chip will start automatically, after trying to

read the external EEPROM, if EEPROM does not exist, the chip will use the default values and the
strap option setting for all internal registers.
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.

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. Micrel provides a Windows 2000/XP based
program for the user to evaluate the KSZ8895’s full feature set. In addition to all the control
registers available via EEPROM programming, a host CPU connected to the KSZ8895’s SPI
interface will be able to access all static MAC table, the VLAN table, dynamic MAC address table
and the MIB counters.
To prepare the KSZ8895 evaluation board for SPI mode configuration follow these steps:
1. Copy the Micrel provided SPI interface software on your computer.
2. Set JP9 as specified in Table 4 for SPI mode configuration.

4.5 LED indicators
Ethernet Port LEDs
There are five columns of LED indicators on the board, one column for each of the five ports. The
LED indicators are programmable to two different modes. You can program the LED mode through
a strap in option on JP23 or in register 11, bit 1. The mode definitions are shown in Table 5. There
are three LEDs per port. The naming convention is “LEDx_y”, where “x” is the port number, and
“y” is the number of the LED for that port.

LED3_y are assigned to Port3.
LED4_y are assigned to Port4.
LED5_y are assigned to Port5.
Power LED
The board also has a power LED D3 for the 3.3V power supply. D3 LED indicates 3.3V Power on
and off.
Interrupt LED
The board also has an Interrupt LED D2 for the Link status change when set the interrupt mask
register 125. D2 LED is turn on to indicate the interrupt to be asserted.
4.6 MII/RMII Ports Configuration
There are two MII/RMII ports on the KSZ8895. One port connects to the fifth MAC in the
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.
The Switch MII/RMII port can be set to PHY mode, MAC mode or SNI mode. In PHY mode, the
Switch MII/RMII port will transmit and receive signals on J6 of the board’s male MII connector.
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
Micrel Inc.

KSZ8895 Evaluation Board User’s Guide
interface is normally used to connect the KS8895 to an external PHY. We also have provisions on
the board to support the SNI 7 wire interface. In SNI mode, the Switch MII port will transmit and
receive signals on header pins. The connections between the header pins and the SNI signals are
shown in the Table 7.
The PHY5 MII/RMII port is used to connect to an external MAC or CPU. This port is only in PHY
mode.

4.7 MDC/MDIO Interface for MIIM Registers and SMI mode
From MDC/MDIO interface to the KSZ8895, use a USB to MDC/MDIO converter that allows
accessing all of PHY related registers and all of the KSZ8895 registers. The user can easily access
the MDC/MDIO interface using a computer connected to the evaluation board’s USB port interface.
Micrel provides Windows based programs for the user to evaluate for both MIIM and SMI. For the
MIIM software to be used all of PHY related registers, please use the software tool in the folder of
MDC_MDIO MIIM of the software directory. For the SMI software to be used all of registers,
please use the software tool in the folder of MDC_MDIO SMI of the software directory.
To prepare the KSZ8895 evaluation board for MDC/MDIO configuration, please follow these
steps:
1. Copy the Micrel provided software on your computer.
2. Set JP2, JP3 and JP4 as specified in Table 8 for MDC/MDIO configuration.

8. Connect the computer’s USB port to the KSZ8895 board with a USB port cable.
9. There are two ways to power up the evaluation board:
a). Connect the 5 VDC power supply to the KSZ8895 when JP47 pin1-2 is closed.
b). 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.
11. Open the Windows and navigate to the directory where the Window MDC/MDIO files are
stored. Click its icon to invoke the software.
12. Program the desired settings using the Micrel MDC/MDIO software. See the software
