1Introduction
The KSZ886X-16 MQL Demo Board is intended to provide a convenient way to evaluate
or demonstrate the functionality and performance of these new Ethernet products from
Micrel. There are two different chips with non-PCI 16-bit bus:
•KSZ8861-16 MQL is a single either copper or fiber dual function port Ethernet MAC
controller.
•KSZ8862-16 MQL is a single copper and fiber port Ethernet Switch.
These Ethernet chips interface with the M16C processor from Renesas to use the 16-bit
generic bus on the demo board.
Micrel provides a basic software driver based on the 16-bit bus solution with which to
evaluate the KSZ886X-16MQL functionality and feature. The software includes a
configuration utility to allow quick and easy device setup.
2Hardware Features
•KSZ8861-16 MQL demo board supports the single either fiber or copper
port Ethernet MAC controller and 16-bit bus interface to M16C
microcomputer.
•KSZ8862-16 MQL demo board supports one copper port and one fiber
port Ethernet Switch and 16-bit bus interface to M16C microcomputer.
•One 64K X 16 1-Mbit SRAM for further software code development.
•UART DB-9 connector as a console serial port.
•ICD connector for In-circuit debugger and programmer.
•One LCD module to display status of the software running and demonstration
information.
•Using the demo board can demonstrate WOL (Wake-on-LAN) functionality for
KSZ8861-16 MQL.
•Management two ports switch or MAC controller.
•Power LED and status LED’s.

L Demo Board User’s Manual
4.1 Host Computer Requirements
The minimum PC requirement for running the software and the Demo Board is an USB
port, serial RS232 port and Microsoft Windows 98, ME, 2000, or XP.
4.2 Demo Board
The Demo Board provides an evaluation and development environment for KSZ886X-16
MQL Ethernet switch or MAC controller with a 16-bit host bus interface. It has push
button switches, LED’s and LCD for user interfaces. One 10/100Base-TX fast Ethernet
port and one 10Base-FL/100Base-SX port are available for different modes of Ethernet
connection.
4.3 ICD In-Circuit Debugger (RTA-FoUSB-MON)
Micrel has programmed the OpenTCP device driver into the Demo Board for
demonstration purposes, so the user can use the Demo Board to run demo software
“TCP_GUI” or “LinkMD” on the Demo Board.
If you want to use the Demo Board as a development platform and program the flash in
the M16C Microcomputer, you need to order the part RTA-FoUSB-MON from Renesas
or its distributors. The part can perform debugging and programming of the Demo Board
by using the host computer’s Universal Serial Bus (USB). The Demo Board will provide
power to the RTA-FoUSB-MON. When connecting the ICD to the Demo Board ensures
that the power source switch on the RTA-FoUSB-MON is in the “TARGET” position. If
the switch is left at “USB” Powered Mode, some MCU pins may be driver to undesirable
levels.
4.4 Software Development Tools
For details of the software development tools and programs, please refer to “Micrel
KSZ886X 16-Bit BSP User’s Manual”.

4.5 Other Connectivity
4.5.1 Power Supply
A single +7.5V DC power supply is used only from this demo kit and plugs into the
power jack J3 on the Demo Board.
4.5.2 Serial Port Cable Connection
A serial female to male cable is used in the demo kit. The cable is connected between the
RS-232 port of the PC and the serial port of the Demo Board. From the console port in
the PC, the user can read/write to registers, send packets and display MIB counters, etc.
4.5.3 Console Port Speed Setting
The serial port data transfer is set the speed at 38400 Bits/Second for normal display in
either a Hyper Terminal or other tools. Figure 2 shows all parameters setting on the
Hyper Terminal.

6.1 Power on the Demo Board
If user needs to update the OpenTCP driver, they can read the Chapter 7 to download the
update driver, otherwise user just connects the RS-232 serial cable between the PC and
the Demo Board. On the PC, open the Hyper Terminal and configure the speed to 38400
Bits/Second as shown in Figure 2, then plug in the 7.5V DC jack to power on the Demo
Board. Normally the Hyper Terminal window will display as shown in Figure 5.

7.2 Board Reset
The KSZ8862-16 MQL Demo Board generates a reset signal from the reset circuitry
during power up. It also provides a push button S4 reset circuit to reset the whole Demo
Board. At power up, the board is automatically reset. User can also press reset button S4
on the board for a manual reset. After any reset, the LED1 and LED2 flash to indicate the
power on self-test, also the LCD module shows the HW/SW board status and system set
up result.
7.3 Clock Scheme
The Ethernet chip reference clock is provided from external 25 MHz crystal (Y1). The
crystal is connected to the X1 and X2 pins on the KSZ8862-16 MQL. This 25 MHz clock
is specified as +3.3V tolerant, +/- 50 ppm. If an oscillator is used, X1 connects to a 3.3V
tolerant oscillator and X2 is no connection.
The M16C microcomputer receives two references clocks, one is the 12 MHz crystal,
connected to Xout/Xin pins, the other is the 32 KHz crystal, connected to XCout/XCin
pins. Both clocks are specified as +5.0V tolerant, +/- 100 ppm.
7.4 POT1 and POT2
Adjust POT1 to change the contrast of the LCD display module.
Adjust POT2 to change the UDP receive value when streaming from Demo Board to PC
