4.0 Hardware Description
The KSZ8895MLU/MLUB 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
KSZ8895MLU/MLUB’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
KSZ8895MLU/MLUB’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 interface. These are to facilitate connections from the switch to an external MAC
or PHY.
The KSZ8895MLU/MLUB 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 is included 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
KSZ8895MLU/MLUB acts as a standalone 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 KSZ8895MLU/MLUB 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 open and JP3 and JP9 are
closed. 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.
