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. The device had been designed with
cost sensitive systems in mind but still offers a multitude of features such as switch management;
port and tag based VLAN; 1/2/4-queue QoS priority; a dual MII/RMII option data interfaces and
CPU control interfaces of SPI, MDC/MDIO with MIIM/SMI. MIIM is the standard IEEE 802.3
MII Management Interface. SMI is non-standard Serial Management Interface that can access all
registers by the Management Data Input/output MDIO interface. The KSZ8864 is an excellent
choice in current complex Ethernet applications with single processor or dual processors, industrial
automatic, automotive, etc. fields and as a standalone 4-port switch.
The KSZ8864 evaluation board is designed to allow the user to experience first-hand the rich
feature set of these existing 4-port switches of KSZ8864CNX/RMNUB. The evaluation board is
highly configurable and easy to use.

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. Or
using Micrel SPI software and your PC, you can access the KSZ8864’s full feature set registers by
the USB to SPI interface. The board also features the MII connectors for the Switch MII/RMII
interface on port 3 and port 4. These are to facilitate connections from the switch to an external
MAC or PHY with MII/RMII interface.
The KSZ8864 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
KSZ8864 acts as a standalone unmanaged 4-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 KSZ8864 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

KSZ8864 Evaluation Board User’s Guide
Micrel Inc. Page 7 5/9/2014
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.

4.3 SPI Mode
From SPI interface to the KSZ8864, use a USB to SPI converter that allows accessing all of the
KSZ8864 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 KSZ8864’s full feature set. In addition to all the control
registers available via EEPROM programming, a host CPU connected to the KSZ8864’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 KSZ8864 evaluation board for SPI mode configuration follow these steps:
1. Copy the Micrel provided SPI interface software on your computer.
2. Set JP3, JP4, JP5 and JP9 as specified in Table 4 for SPI mode configuration.

4.4 10/100 Ethernet Ports
There are two 10/100 Ethernet ports on the KSZ8864 evaluation board. The ports J1 and J2 can be
connected to a traffic generator/analyzer or a SmartBit via standard RJ45 connectors using CAT-5
cables. Each port can be used as either an uplink or downlink. All ports support auto MDI/MDIX so
there is no need for cross over cables.
J1 = RJ45 connector for port 1
J2 = RJ45 connector for port 2
4.5 LED indicators
Ethernet Port LEDs
There are two columns of LED indicators, one column for each of the two 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.
Table 5 LED Modes
Mode 0 Mode1
PxLED1 = Link/Act PxLED1 = 100Link/Act
PxLED0 = Speed PxLED0 = Full Duplex
P1LEDy are assigned to Port1
P2LEDy are assigned to Port2
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 turns on to indicate the interrupt to be asserted.
4.6 MII/RMII Port Configuration
There are two MII/RMII ports on the KSZ8864. One port connects to the port 4 MAC4 in the
KSZ8864, and we refer to it as the port 4 Switch SW4-MII/RMII port. The second MII/RMII port

KSZ8864 Evaluation Board User’s Guide
Micrel Inc. Page 11 5/9/2014
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. Both MAC4 and MAC3 also can
be configured to RMII interfaces mode for SW4-RMII and SW3-RMII by the strap pins P1LED0
and P2LED0, P1LED0 is pulled down (JP39 closed) for SW4-RMII mode, P2LED0 is pulled down
(JP42 closed) for SW3-RMII mode.
The Switch MII port can be set to PHY mode, MAC mode. In PHY mode of the SW4-MII, the
Switch MII port will transmit and receive signals on J6 of the board’s male MII connector. This
mode is usually used to connect the KSZ8864 to a CPU. In MAC mode of the SW4-MII, the Switch
MII port will transmit and receive signals on J7 of the board’s female MII connector. This interface
is normally used to connect the KSZ8864 to an external PHY. In PHY mode of the SW3-MII, the
Switch MII port will transmit and receive signals on J8 of the board’s male MII connector. This
mode is usually used to connect the KSZ8864 to an external MAC. In MAC mode of the SW3-MII,
the Switch MII port will transmit and receive signals on J9 of the board’s female MII connector.
This interface is normally used to connect the KSZ8864 to an external PHY.
