CAUTIONARY NOTES
1) Electrostatic Discharge (ESD) prevention measures should be used when handling this
product. ESD damage is not a warranty repair item.
2) Axiom Manufacturing does not assume any liability arising out of the application or use of
any product or circuit described herein; neither does it convey any license under patent
rights or the rights of others.
3) EMC Information on the M52259DEMOCOM board:
a) This device complies with FCC Rules, Part 15. Operation is subject to the following
conditions:
i) This device may not cause harmful interference, and
ii) This device must accept any interference received, including interference that may
cause undesired operation.
b) This product, as shipped from the factory with associated power supplies and cables,
has been verified to meet with FCC requirements as a CLASS A product.
c) This product is designed and intended for use as a development platform for hardware
or software in an educational or professional laboratory.
d) In a domestic environment, this product may cause radio interference in which case the
user may be required to take adequate prevention measures.
e) Attaching additional wiring to this product or modifying the product operation from the
factory default as shipped may effect its performance and cause interference with other
apparatus in the immediate vicinity. If such interference is detected, suitable mitigating
measures should be taken.
TERMINOLOGY
This development board uses option selection jumpers. A jumper is a plastic shunt that con-
nects 2 terminals electrically. Terminology for application of the option jumpers is as follows:
Jumper on, in, or installed - jumper is installed such that 2 pins are connected together.
Jumper off, out, or idle - jumper is installed on 1 pin only.
Cut-Trace – a circuit trace connection between component pads. The circuit trace may be cut
using a knife to break the default connection. To reconnect the circuit, simply install a suitably
sized 0-ohm resistor or attach a wire across the pads.
Signal names document followed by an asterisk (*) denote active-low signals.

OVERVIEW
The M522259DEMO consists of the M52259DEMOMCU and the M52259DEMOCOM boards
connected via 0.5mm stack connectors. The M52259DEMO allows the user to easily add
functionality by simply matching the stack connector pin-out.
The M52259DEMOMCU board features the MCF52259 ColdFire microcontroller. An, open-
source, USB-BDM has been integrated to simplify application development and debug. A
USB port with mini-AB USB connector is also provided. Four user LEDs and 2 user push but-
tons complete the M52259DEMOCOM board features. Additional MCU features are available
at the stack connector.
The M52259DEMOCOM board expands the M52259DEMO feature set. The
M52259DEMOCOM supports 10/100 Ethernet, high-speed CAN, and RS-232 functionality.
Please refer to the M52259DEMOCOM User Guide for details.
GETTING STARTED
To get started quickly, please refer to the M52259DEMO Quick Start Guide. This quick start
will illustrate connecting the board to a PC, installing the correct version of CodeWarrior De-
velopment Studio, and running a simple application.
POWER
Power for the M52259DEMOCOM board is provided through the stack connectors from the
M52259DEMOMCU board.
RESET
Reset to the Ethernet PHY is provided through the stack connectors from the
M52259DEMOMCU board.

CONNECTORS
J3
An Ethernet connector at J3 supports 10/100 Ethernet network connectivity. The connector is
arranged tab-down and includes integrated magnetics. The Ethernet Port applies a Micrel
KZS8041 10/100 Ethernet PHY configured for MII operation only. The PHY connects to the
Fast Ethernet Controller (FEC) signals from the MCF52259 MCU on the M52259DEMOMCU
board.
Two, green, status indicators are provided to indicate network traffic connection status
Figure 1: Ethernet Status Indicators
SPD ON – 100BaseT connection, OFF – 10BaseT connection
LNK_ACT ON – indicates network traffic activity
UART0
A right angle, 9-pin Dsub connector supports serial communications to the target MCU on the
M52259DEMOMCU boards. The RS-232 PHY is connected to UART 0 on the target MCU. A
ferrite bead on shield ground provides conducted immunity protection. Handshaking signals
RTS and CTS are also routed to the target MCU. RTS is biased for handshaking during 2-wire
operation.

CAN_PORT
A 3-pos connector at CAN_PORT provides CAN port access for the M52259DEMOCOM. A
TJA1050 device provides the CAN PHY interface. This device is capable of communicating up
to 1 Mbaud.
Differential CAN signal termination is applied. A 120-ohm termination resistor with option
jumper allows termination to be applied or removed. The CANT_EN option jumper applies or
removes the CAN termination.
