iC5500 On-Chip Analyzer is a universal on-chip emulation platform, which allows debugging and testing

embedded platforms based on various microcontroller architectures.. To connect to the target microcontroller,

based on a specific architecture, a connecting 40-pin flat cable (which also comes with the iC5500), a target

specific debug cable adapter and architecture specific license are required. Note that in some configurations,

multiple licenses are required (e.g. debug, trace and multicore license) and earlier mentioned 40-pin flat cable is

not required when the necessary connection cables come with the debug cable adapter (e.g. IC50152, IC50115,

IC50163) already.

Typically, the IC5500 already comes assembled and preprogrammed with all purchased licenses except for

winIDEA license, which is not required for 28 days (evaluation period) from the day of the first use. It remains

to the user only to connect a specific cable adapter and connecting the debug and test tool to the embedded

target.

iC5500 Base Unit

iC5500 Base Unit is a base platform connecting to the PC via the TCP/IP or the USB 3.0 port. The iC5500 USB

3.0 port is backward compatible with the USB 2.0 ports on the PC side.

Make sure that the USB 3.0 cable delivered along the iC5500 is being used for the USB 3.0 connection. It has

been confirmed that many USB 3.0 specified cables don’t work reliably. When using a cable of your own

selection, test it well in conjunction with the iC5500 before use.

TCP/IP communication can be used to access the iC5500 from a distant PC or when a single iC5500 unit is

shared between multiple PCs or users.

USB 3.0 communication should be used to get the most out of the iC5500 in terms of capturing trace information

from the microcontroller.

iC5500 Base Unit features 1GB analyzer storage buffer, which in conjunction with the USB 3.0 communication

to the PC, can provide infinite or at least very long trace captures.

There are three status LEDs on the iC5500 Base Unit. The LEDs inform the user of the current status of the

iC5500. Their meaning is:

–When lit, the unit is turned on

R –When lit, the target application being controlled is running

F –When lit, the unit is free for communication, i.e. winIDEA can connect to it.

Valid input voltage range for all debug signals is between 1.8 - 5.5V

All debug signals have a 47E series termination/protection resistors and ESD protection devices. All inputs have

10K pull-up resistor, except TDO input which has a 10K pull-down. Bidirectional debug signals have pull-up

resistors: TMS and TDI have 10K, RESET has a 1K. The latter is buffer-driven to prevent current flow into the

unpowered iC5500 from a powered target board.

Debug signals are additionally protected with 100mA resettable fuses.

The TAR_VREF (target reference voltage) pin has a 100K input impedance.

Connecting debug cable adapter to the DTM

Debug cable adapters, which come without any cable attached are used in conjunction with a connecting 25 cm

long 40-pin flat cable (which comes delivered with the iC5500) and connect always to DTM #1 connector

located on top of the iC5500.

Example of the debug cable adapter for Cortex architecture without the attached cable

25 cm 40-pin flat cable

Connecting guidelines for debug cable adapters delivered without pre-attached flat cable:

Be gentle when connecting one connector to the other! Do not use any excessive force, observe the

orientation key and connector notches!

First, connect the 25 cm 40-pin flat cable to the iC5500 DTM #1 connector.

The cable should be facing away from the iC5500 Base Unit with the red (edge) wire on the side of the

DTM #1 marking.

Align the orientation key/notch of the cable connector with the notch on the iC5500 40-pin connector

marked with #1.

Press the cable connector carefully straight down until the latches lock. Do not press only on one side of

the connector as this can (in worst case) bend the corner pins of the DTM #1 connector.

Next, connect the debug cable adapter to the other side of the 25 cm 40-pin flat cable.

Align the orientation key/notch on the 40-pin debug cable adapter connector with the connector on the

40-pin flat cable.

Press the cable carefully straight down until the latches lock. Do not press only on one side of the

connector as this can (in worst case) bend the corner pins of the adapter’s connector.

Finally, connect the debug cable adapter to the target.

Connecting flat cable to the iC5500 Base Unit (DTM #1 and #2 connectors)

When default 25 cm 40-pin flat cable is not suitable for some reason (e.g. too short to reach the target or too long

for the trace to work at maximum microcontroller frequency), additional cables can be ordered separately:

- IC50020-10 (10cm)

- IC50020-25 (25cm) e.g. in case if the original cable gets damaged.

- IC50020-40 (40cm) *might not work at full speed

- IC50020-60 (60cm) * might not work at full speed

With all lengths longer than default 25 cm, it’s up to the user to determine working debug tool settings

and to test and confirm a working operation of the whole setup. Note that iSYSTEM provides no

guarantee for working operation for these lengths.

Certain debug cable adapters (for example 16-bit Nexus (IC50152), 16-bit ETM (IC50115) and 10-pin Infineon

DAP (IC50163)) come delivered with two, 30-pin and 40-pin flat cable pre-attached. With these, 25 cm 40-pin

flat cable, which comes with the iC5500, is not needed.

Example of Infineon DAP debug cable adapter with two flat cables pre-attached

Connecting guidelines for debug cable adapters with two flat cables:

Be gentle when connecting one connector to the other! Do not use any excessive force, observe the

orientation key and connector notches!

First, connect the 30-pin flat cable to the iC5500 DTM #2 connector.

The cable should be facing away from the iC5500 Base Unit with the red (edge) wire on the side of the

DTM #2 marking..

Align the orientation key/notch of the cable connector with the notch on the iC5500 30-pin connector

marked with #2.

iSYSTEM, March 2017 5/66

Press the cable connector carefully straight down until the latches lock. Do not press the connector only

on one side as this can (in worst case) bend the corner pins of the DTM #2 connector.

Next connect the 40-pin flat cable to the iC5500 DTM #1 connector.

The cable should be facing away from the iC5500 Base Unit with the red (edge) wire on the side of the

DTM #1 marking..

Align the orientation key/notch of the cable connector with the notch on the iC5500 40-pin connector

marked with #1.

Press the cable connector carefully straight down until the latches lock. Do not press the connector only

on one side as this can (in worst case) bend the corner pins of the DTM #1 connector.

Finally connect the debug cable adapter to the target.

Disconnecting guidelines:

In order to disconnect the flat cables from the iC5500 DTM #1 or #2 connector, squeeze the two metal latches

on the cable connector from the side and pull the cable from the iC5500 DTM #1 respectively #2 connector.

iC5500 I/O Module (optional)

Through this module the iC5500 development and test system can connect to the analog and digital world around

the microcontroller. It also allows building up a so called Hardware-In-the-Loop (HIL) test environment.

Analog and/or digital signals from the target can be measured, observed and traced along the program execution

flow. At the same time, the iC5500 I/O module can generate analog and/or digital stimulus towards the target.

Module is optional and can be added to the iC5500 system at any time.

Power Supply

A round 3-pin power connector is located on the rear of the iC5500 base unit.

Power connector pinout, view from the rear of the Emulator

The iC5500 unit accepts a wide input voltage range from 10V to 24V DC, thus enabling the Emulator to work

also with a 12V or 24V car battery. Power consumption is up to 15W (iC5500 without optional I/O module).

The necessary power supply (IC30000-PS) comes along the iC5500 unit.

IC30000-PS

An optional 12V power supply for Car (cigarette lighter) plug can be ordered under the IC30000-PS-CAR12V

ordering code.

IC30000-PS-CAR12V

Note: Use only original iSYSTEM accessories for powering the iC5500. If you wish to use a power supply

different from the delivered one, please consult with iSYSTEM first.

iC5500 System Power On / Power Off Sequence

In general, the iC5500 Analyzer and the target must be in the same power state. Both must be on, or both off.

Level translators on the DTM module go high-Z when either emulator or target (TAR_VREF) supply is off.

Therefore, it is recommended to use ‘Vref’setting for the ‘Debug I/O levels’ in winIDEA ‘Hardware/Emulation

options/Hardware’ tab. Note, this is not applicable when using Hot Attach operation.

iSYSTEM, March 2017 9/66

In practice, typically the iC5500 and the target cannot be powered simultaneously. To prevent hardware damage

due to the incorrect power on or power off sequence of the system, follow the next rule: When powering the

system, switch ON the iC5500 before the target; when shutting down the system, switch OFF the target

before the iC5500!

If emulator is switched off but target is left on, forcing 5V through protection diodes on the DTM I/O pins could

activate level-translation buffers in improper way. They in turn could drive excessive current through 47E

resistors that would eventually be overheated and completely blown. The same can happen in reversed power

state and emulator is set for internal 5V source, for example.

iSYSTEM, March 2017 10/66

Grounding Wire Use

In case of the on-chip emulation, it has been proven that a development tool can be damaged at the moment

when the emulator's debug connector is plugged into the target system when neither the target nor the emulator

are powered up yet. At this point in time, there could be ground potential difference between the emulator and

the target way over 1000V. Such voltage difference is then discharged over the emulator and the target, which

can destroy electronic components of the emulator and/or the target.

The voltage difference can be introduced by:

power supply (target, emulator), which does not have the power outlet ground connected with the power

supply ground.

power outlets which have different ground potentials

PC, when the iC5500 connects to the PC through the USB port

Connecting a dedicated grounding wire, which is shipped with the iC5500 unit, between the iC5500 system and

the target before the target debug cable adapter is connected to the target, makes the complete development

system even more robust and resistant to the mentioned electrical discharge problem - despite the fact the iC5500

development system features already a high quality protection on all connecting signals by default.
