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 refer ence for adva nced users . Throughout the manual, many references to the AVR microcontrollers are made in short form, i.e. AT90S2313 is referred to
as S2313 and so on.
The user shoul d install th e latest ver sion of the AV R Studio ava ilable 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.

1.4 Checklists When the detailed descrip tions in the
Connecting to the Target Applicatio n
and in the
Configurat ion
sections have been used and you are beginning to feel comfortable with
the use of the ICE 20 0, you can use the c heckli sts at th e end of the se secti ons for fa st
setup of a new project. The checklists are of great help for getting the debugging system
online without pro blems. Ho wever, novi ce user s should also ch eck that the opera ting
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 microcontrollers 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 produ ced in the same proce ss techno logy as the microcontroller it is emulating. This provides identical electrical
characteristics . On- board d ebugging reso urces ensur e non-intr usiv e softwa re emulation. 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, un limited n umber of break points, symbo lic d ebuggi ng and full memo ry
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.

General Description
3-2 AVR ICE 200 User Guide
The main board (Figure 3-2) contains the program memory (overlay memory) which
holds the application code that is being emulated. The main board also contains logic for
communicating with the host PC, and the breakpoint lo gic. The level converters allow
the target to operate at a different supply voltage fr om that of the emulator. The level
converters also protect the emulator and the target from being damaged if only one of
them is powered. Due to this feature, a strict power-up sequence is not required.
