4.0 Hardware Description
The KSZ8895ML 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 KSZ8895ML’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 KSZ8895ML’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 KSZ8895ML 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.
