Introduction

The AT90ICEPRO is a real time In-Circuit Emulator (ICE) for all AT90S1200, -S2313,

-S2323, -S2333, -S2343, -S4414, -S4433, -S4434, -S8515 and -S8535 devices. It can

be upgraded to support future AVR®parts. It is controlled by AVR Studio, which is a pro-

fessional front-end for both high-level and assembly level debugging. AVR Studio is

described in Section 1 in the Development Tools User Guide and must be studied care-

fully in order to take full advantage of this product.

The AVR AT90ICEPRO ICE system consist of the following elements:

■AVR ICE Unit

■Pod card AT90ADCPOD

■Pod Cable

■AT90S1200/-2313 probe with cable (DIL20)

AVR AT90ICEPRO with AT90ADCPOD

The AVR ICE unit is the main part of the AVR AT90ICEPRO system. AVR Studio, which

runs on a host PC, controls the ICE unit. The AVR ICE unit must be connected to an

available RS-232 port on the host PC with the supplied RS-232 cable. AVR Studio auto-

matically detects if there is an emulator present on one of the PC’s serial ports. Note

that if no ICE is found,

AVR

Studio will show “Simulator” in the lower right corner of the

main window. If the ICE is found, “AVR Emulator” will be indicated and your connections

are correct. AVR Studio will issue a warning if a program previously run in emulator

mode is started in simulator mode.

AT90ADCPOD

AT90ADCPOD is the pod card used for the processors, AT90S1200, -S2313, -S2323, -

S2333, -S2343, -S4414, -S4433, -S4434, -S8515, and -S8535. The pod contains the

analog comparator, the analog to digital converter, a clock circuit for handling of XTAL

and TOSC signals from the target application, a reset button and a voltage conversion

circuit. 11 different jumpers and one switch can be set on the pod card to select between

the different functions.

The pod card is connected to the AVR ICE unit using the pod cable (the wide cable),

and to the user application using the 8-pin, 20-pin, 28-pin, or 40-pin probe.

Note:

It is extremely important that the probe cable is correctly connected to the user

application. The colored wire of the probe cable indicates pin 1 of the AVR

device.

Preparing the

AVR

AT90ICEPRO

System for Use

Complete the following procedure in order to start using the AVR ICE.

Before connecting the probe cable to the user application:

■Connect the pod card to the AVR ICE unit with the pod cable.

■Connect the appropriate probe to the pod.

■Connect the RS-232 cable between the AVR ICE unit and an available serial port on

the host PC.

■Connect power supply (9 - 15 VDC) to the AVR ICE unit.

■Turn the power on and check that the red LED marked “POWER” is lit.

■After a short time (≤10 sec.), the green LED marked “READY” will be lit and the

AVR

ICEPRO system is ready.

■Turn off the power.

Plug the probe into the application, paying attention to connect it correctly. If it is not

connected correctly, the AVR AT90ICEPRO system may be damaged. The colored wire

of the probe cable indicates pin 1 of the AVR device.

■When the probe is correctly connected to the application, check the jumper marked

“EXT. POWER” on the probe circuit board. If the application is powered from the AVR

ICE unit, the jumper must be mounted. If the application is going to use its own power

supply, the jumper must be removed.

■Make sure that all other jumpers and switches (clock, timer, analog comparator and

device) are set according to your application. Details on these jumper settings are

located in Section 4.

■When all jumpers are set correctly, turn on the power. When the green LED is lit, the

AVR AT90ICEPRO system is ready for use. Start AVR Studio, and begin your AVR

emulation session.

Section 3

Select Between

Different AVR Devices

The selection between different AVR devices must be done both in AVR Studio and on

the pod card. In AVR Studio, choose the device you want to emulate in the Device menu

in Emulator Options. On the pod card, make sure to use the appropriate probe cable (20

pins for 20 pin device and so on) and connect your application to the connector labeled

with the correct part number. Please note that it may damage your AT90ICEPRO if you

plug the probe cable into the wrong connector.

To use AT90S2323 ar AT90S2343, the jumpers on the connectors labeled PB3 and

PB4 must be set. Table 3-1 below shows how to set these jumpers.

For other devices these jumpers are not used.

To use AT90S2333, AT90S4433, AT90S4434 or AT90S8535, the 10 lead cable on the

pod must be mounted. Table 3-2 below shows where to connect this cable.

For other devices this cable is not used.

Section 4

The AVR AT90ICEPRO

Power System

The AVR AT90ICEPRO system has an internal power regulator that can deliver 15W of

power at 5V. The AVR ICE itself uses about 10W, so if the user application is powered

from the AVR AT90ICEPRO system, it can not use more then 5 W (i.e. 5V/1A). If this

value is exceeded, the AVR AT90ICEPRO system may be damaged or not work prop-

erly.

The power supply delivered with your AT90ICEPRO is dimensioned to meet the require-

ments of the emulator. If another power supply is used, it should supply a voltage

between 9 and 15 VDC, and minimum 20W. The battery eliminator connector on the AVR

AT90ICEPRO system is a standard type with 2.1 mm center tap. Ground should be con-

nected to the center tap.

If the target application needs to be powered from the emulator, the jumper labeled

“EXT.POWER” should be mounted. Jumpers labeled “PW2”, “PW1”, and “PW0” can all

be removed when external power is selected.

If the target application runs on a supply voltage other than 5V, and you want to emulate

your system at that voltage, the jumper named “EXT.POWER” must be removed. The

pod card must also be set to convert voltages to the required voltage. Use Figure 13-2

to find what the settings on the jumpers named “PW2”, “PW1”, and “PW0” should be.

Figure 4-1.
