KSZ8864 Evaluation Board User’s Guide 1.0 Introduction The KSZ8864 is Micrel Operations’ new generation integrated 4-port switch with a 64-pin small package. The KSZ8864 device consists of two PHYs and four MACs. Two of MACs support either MII or RMII interfaces for dual processor/DSP data transfer. Higher speed SPI and MDC/MDIO interfaces can fully manage the 4-port switch by the processor.
KSZ8864 Evaluation Board User’s Guide 4.0 Hardware Description The KSZ8864 evaluation board is in a compact form factor and can sit on a bench near a computer/laptop. There are three options for configuration: strap in mode; EEPROM mode; and SPI mode. Strap in mode configuration is easily done with on board jumper options. EEPROM mode and SPI mode are accomplished through a built in USB port interface. Using Micrel EEPROM software and your PC, you can reprogram the EEPROM on board by the USB port.

In this mode, the KSZ8864 acts as a standalone unmanaged 4-port switch.
KSZ8864 Evaluation Board User’s Guide 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 KSZ8864. Table 1 describes the jumpers and their function in the open or closed state.

Connect the computer’s USB port to the KSZ8864 board with a USB port cable. There are two way to power up the evaluation board: a). Connect the 5 VDC power supply to the KSZ8864 when JP47 pin1-2 is closed. b). 5 VDC power source from the USB port when JP47 pin 2-3 is closed. 5. The KSZ8864 will power up in its default configuration if there is no information in the EEPROM. 6.

Program the desired settings using the Micrel SPI interface software. See the software operation description section 5.7 for details. 4.4 10/100 Ethernet Ports There are two 10/100 Ethernet ports on the KSZ8864 evaluation board.
KSZ8864 Evaluation Board User’s Guide connects to the port 3 MAC3 in the KSZ8864, and we refer to this as the port 3 Switch SW3-MII/RMII port. Both the SW4-MII and the SW3-MII are default available as PHY modes. SW4-MII can be configured to MAC mode by setting pin [47, 48] =11 and SW3-MII can be configured to MAC mode by setting bit 6 = ‘1’ in the register 223.
