1.6 Getting Started

To get started quickly, please refer to the DEMO9S08AC60E Quick Start

Guide. This guide will walk you through connecting your DEMO9S08AC60E

to your PC, running a test program, and installing CodeWarrior Development

Studio.

1.7 Memory Map

The table below shows the MC9S08AC60 memory map. Accessing reserved

memory locations will produce unpredictable results. Accessing

unimplemented locations will produce an illegal-address reset.

$1800 - $185F High Page Registers 96 Bytes

$1860 - $FFFF Flash 59,296 Bytes

1.8 Development Support

Application development and debug for the MC9S08AC60 is supported

through the on-board USB - BDM interface (J33). There is also a 6 pin stand

alone BDM interface available (J32). This header is non-populated in the

default configuration and can be installed by the user if needed.

DEMO9S08AC60E User’ s Guide, Rev. 0.1

Freescale Semiconductor 13

1.8.1 Integrated BDM

The DEMO9S08AC60E features an integrated USB-BDM debugger from P&E

Microcomputer Systems. All necessary signals are provided via the integrated

debugger. A USB type B connector (J33) provides the connection between the

DEMO9S08AC60E and your host PC.

The integrated debugger provides the DEMO9S08AC60E with power

eliminating the need to power the board externally. Power is derived from the

USB bus, therefore total current consumption should not exceed 500mA.

Excessive current drain will violate the USB spec and damage to your Host

PC’s USB hub or the DEMO9S08AC60E could occur.

1.8.2 BDM Header

J32 is the stand alone BDM header. Use of this port requires the user to solder

a 2 x 6 100 mil center header on the board. The pinout is as follows:

1.8.3 Socketed MCU

The MC9S08AC60 silicon is socketed on the DEMO9S08AC60E board. This

socket is an open top, spring actuated, 0.8mm pitch socket. It is made by Wells

Electronics, part number 7314-064-0-08. Before connecting power to the demo

board the silicon should be installed in this socket. Using your thumb and index

finger, press down on the socket until it is fully actuated. Place the silicon in the

socket with a vacuum pen or other chip lifting device. Pin 1 of the silicon

(denoted by an indented dot) should be in the bottom left hand corner, towards

the USB connector J33. Release the socket. The MC9S08AC60 silicon should

be centered within the socket and firmly held in place.

1.9 Power

The DEMO9S08AC60E allows the user to power the board in several different

ways.

1.9.1 USB-BDM Interface

The default power option is to power the board through the integrated

USB-BDM interface. To power the board in this manner, simply connect the

supplied USB cable from the USB connector on the DEMO9S08AC60E (J33)

to a USB port on your host computer. LED D1 will light green to let you know

that power has been correctly applied to the board. When powering the board

through the USB-BDM interface, jumpers W1, W2, and W3 should be in their

default position as described below

Table 1-3 Jumper Settings in USB Power Mode

Jumper Default

Position Setting Description

W1 2-3 5V Sets the board for 5V

W2 2-3 USB Sets the board to be

W3 1-2 P_IO_5V

Outputs 5V on pin 1 of

the I/O connector, J35.

This jumper should be

removed if you do not

want to output 5V on

this pin.

1.9.2 External Power Jack

The DEMO9S08AC60E can also be powered externally through the barrel

connector J1. This connector is a 2.1 mm, center positive connector. Voltage

supplied through this connector should be between positive 7 volts and positive

12 volts DC. To power the board through the external power jack, jumper W2

should be moved to the 1-2, EXT position. LED D1 will light green to let you

know that power has been correctly applied to the board. Jumper settings are

detailed below

W3 1-2 P_IO_5V

This jumper should be

removed if you do not

want to output 5V on

this pin.

DEMO9S08AC60E User’ s Guide, Rev. 0.1

Freescale Semiconductor 15

1.9.3 I/O Connector

The DEMO9S08AC60E can also be powered through pin 1 of the I/O connector

J35. To power the board in this manner the jumper on W2 should be removed

and positive 5V DC should be applied on pin 1 of J35. This voltage input is not

regulated on the board so care should be taken to provide a clean 5V signal.

LED D1 will light green to let you know that power has been correctly applied

to the board. Jumper settings are detailed below

16 Freescale S emiconductor

1.9.4 3 Volt Operation

The DEMO9S08AC60E can be run with VDD set to either 5 volts or 3 volts. To

run the board at 3V when using any of the three power options, move jumper

W1 to the 1-2, 3V position.

1.10 Reset Switch

The reset switch (SW6) provides a way to apply a reset to the MCU. The reset

switch is connected directly to the RESET_B signal of the MCU. A 10K pull up

resistor to VDD on the RESET_B signal allows for normal operation. When the

reset switch is pressed the RESET_B signal is grounded and the MCU

recognizes a reset.

1.11 Clock Source

An on-board 4MHz crystal (Y1) is connected between the XTAL and EXTAL

pins of the MCU. There is also an option for the user to add a canned oscillator

to the board. To add an oscillator, the zero ohm resistors R18 and R20 should

be removed and an oscillator should be installed in the J2 footprint. This

footprint accepts either 14 pin or 8 pin oscillators. To go back to the crystal

option, the oscillator should be removed from J2 and zero ohm resistors should

be reinstalled in the R18 and R20 footprints.

1.12 RS-232

An RS-232 translator provides RS-232 communication on com connector J34.

This connector is a 9 pin Dsub right angle connector. TXD and RXD signals are

routed from the MCU to the RS-232 transceiver.

1.13 User Options

The DEMO9S08AC60E includes various user input and output devices to assist

in application development and silicon evaluation. These devices include four

pushbutton switches, a 10 LED light bar, 8 rocker switches, an accelerometer,

a light sensor, and a potentiometer.

1.13.1 Pushbutton Switches

Four pushbutton switches provide momentary active low input for user

applications. MCU port pins can be disconnected from these pushbutton

1.13.2 Light Bar

A 10 red LED light bar (LED1) is provided to assist users during code

development. The LEDs are active low and are illuminated when a logic low

signal is driven from the MCU port pin. Eight of the LEDs on the light bar are

connected to port F. The other two are spare and are user assignable. They are

connected to test pads on the board that a user can solder to a desired port pin

or other signal. Port F pins can be disconnected from the light bar by removing

the appropriate jumper. The light bar is connected as described below

1.13.3 Rocker Switches

Eight rocker switches (SW5) are provided for user application development.

These switches are active low and input a logic low when set to the closed

position. There are no external pullups on these switches so the internal pullups

should be enabled on the MCU port pins to ensure proper operation. Port A pins

can be disconnected from the rocker switches by removing the appropriate

jumper. The rocker switches are connected as described below

1.13.4 Accelerometer

A Freescale MMA6270QT accelerometer (U5) is provided to assist users in

developing accelerometer based application code. The MMA6270QT provides

output data in the X and Y direction and has a sleep mode. The MMA6270QT

is a 3.3V part and is connected to the MC9S08AC60 through the use of a level

translator. The X and Y outputs are connected back to the MCU both directly

from the accelerometer (3.3V signals) and amplified to 5V through the use of

op-amps. The sleep mode is an active low input to the accelerometer. When a

logic low is applied to the sleepmode pin the device outputs are turned off,

providing significant reduction of operating current (low to 3 uA typically). The

MCU port pins can be disconnected from the accelerometer by removing the

appropriate jumper. The accelerometer is connected as described below

1.13.5 Light Sensor

A photo detect IC (U4) combines a photodiode and a current amplifier on a

single IC to provide variable current. The light sensor is connected to the MCU

on PTD1. PTD1 can be disconnected from the light sensor by removing jumper

J4.

1.13.6 Potentiometer

A 10 Kohm thumb-wheel potentiometer (VR1) provides variable resistor for

users to assist them in application development. The potentiometer is connected

to the MCU on PTD0. PTD0 can be disconnected from the potentiometer by

removing jumper J3. The voltage seen on PTD0 is the result of a voltage divider

that changes as the potentiometer is turned.

1.13.7 I/O Connector

A 40-pin I/O connector (J35) is available for user expansion. This connector is

located on the bottom of the board and has holes so that pins of a connecting
