1.1 About this

Manual This user guide serves as a reference manual for the Atmel AVR®ICE 200™in-circuit

emulator. The AVR ICE 200 User Guide is an easy introduction on how to use the ICE

200, and a detailed reference for advanced users. Throughout the manual, many refer-

ences to the AVR microcontrollers are made in short form, i.e. AT90S2313 is referred to

as S2313 and so on.

The user should install the latest version of the AVR Studio available on the Atmel

web site.

1.2 Helpful

Information This manual contains helpful information to improve the reliability, performance, and

longevity of the ICE 200 and the target system.

NOTICE

This is a Notice...

Please follow the instructions in a NOTICE carefully.

1.3 Tips Some sections contain useful tips for using the ICE 200. All the tips are emphasized as

shown in the example below.

©Tip! This is a tip!

1.4 Checklists When the detailed descriptions in the

Connecting to the Target Application

and in the

Configuration

sections have been used and you are beginning to feel comfortable with

the use of the ICE 200, you can use the checklists at the end of these sections for fast

setup of a new project. The checklists are of great help for getting the debugging system

online without problems. However, novice users should also check that the operating

conditions of the target system are compliant to the requirements of ICE 200. This is

described in the

Using the ICE 200

section.

1.5 Related

Documentation The Atmel CD-ROM contains various documentation relating to the use of AVR micro-

controllers and of the debugging tools including AVR Studio User Guide, AVR

Assembler User Guide and complete microcontroller datasheets.

Introduction

The ICE 200 in-circuit emulator provides an easy way of debugging embedded systems

that utilizes the Atmel AVR microcontroller. It emulates 11 different devices of the AVR

and the Tiny AVR families.

The philosophy of the ICE 200 is to provide an easy-to-use debugging platform, with a

minimum of differences between the emulator and the actual processor it is emulating.

The AVR emulator chip used by the ICE 200, is produced in the same process technol-

ogy as the microcontroller it is emulating. This provides identical electrical

characteristics. On-board debugging resources ensure non-intrusive software emula-

tion. The ICE 200 hardware also includes an automatic configuration system that makes

the process of connecting the target to the emulator an easy task.

Figure 2-1.

The ICE 200 Components

When used with the AVR Studio debugging environment, the ICE 200 gives the user full

run time control, unlimited number of breakpoints, symbolic debugging and full memory

and register visibility. Multiple ICE 200 emulators can be used by AVR Studio at the

same time, only limited by the number of serial ports available, giving a high degree of

flexibility.
