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 DEMOAC board:

a) 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.

b) This product is designed and intended for use as a development platform for hardware

or software in an educational or professional laboratory.

c) In a domestic environment, this product may cause radio interference in which case the

user may be required to take adequate prevention measures.

d) 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 applies option selection jumpers. Terminology for application of the
option jumpers is as follows:

Jumper on, in, or installed = jumper is a plastic shunt that fits across 2 pins and the shunt is
installed so that the 2 pins are connected with the shunt.

Jumper off, out, or idle = jumper or shunt is installed so that only 1 pin holds the shunt, no 2
pins are connected, or jumper is removed. It is recommended that the jumpers be placed
idle by installing on 1 pin so they will not be lost.

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 followed by an asterisk (*) denote active-low signals.

FEATURES

The DEMOAC provides a platform supporting a line of Freescale microcontrollers which are
part of the Flexis Continuum. Target microcontrollers mount on plug-in modules to support
quickly changing the target MCU. Available microcontrollers for the DEMOAC include; the
ColdFire V1 MCF51AC256, and the MC9S08AC128/60/16. Application development on the
DEMOAC is quick and easy with the integrated USB-BDM, sample software tools, and exam­ples. An optional BDM_PORT port is also provided to allow use of an external BDM cable. An
80-pin MCU_PORT connector provides access to all IO signals on the target MCU. An ex­panded feature set, including an E-Field sensor, is provided on the DEMOACEX board. The
DEMOACEX connects to the DEMOAC through the 80-pin MCU_PORT connector.
