20-pin ARM pinout
When connecting the BlueBox to the new embedded target for the first time, double
check that the debug adapter pinout matches with the target debug connector. Note
that a mismatch can result in a hardware failure.
The debug adapter features resettable fuses on all pins except for pin 11 and 19. These fuses
protect debug signals against overcurrent and cycle back to a conductive state after the
excessive current fades away.
The debug adapter connects to the target via a 20-pin 2.54 mm connector, for example
Yamaichi FAS-2001-2101-2-0BF. A target should feature a matching part, for example WÜRTH
ELEKTRONIK 61202021621.

An adapter connecting at the end of the Mictor 38-pin ARM ETM 16-bit Debug Adapter is
available for Texas Instruments 60-pin MIPI pinout and must be ordered separately under the
IAMIC38MIPI60TMS570 ordering code.
Ordering code
IAMIC38MIPI60TMS570
The iC5000 and the iC5700 can trace up to 16 trace data lines. The target
microcontroller has to be configured for 16-bit trace port operation if the target
features 60-pin MIPI connector with 32 data trace lines connected.
Note that signal naming in iSYSTEM documentation uses target signal names and not
the ones from the MIPI standard. Refer to ‘MIPI Alliance Recommendation for Debug
and Trace Connectors’ and ‘ARM Target Interface Connections’ documentation for more
information about signal names and their functions.
The debug adapter connects to the target via a 60-pin MIPI connector, for example Samtec
QTH-030-01-L-D-A. A target should feature a matching part, for example Samtec QSH-030-01-L-

10-pin Cortex-M pinout
10-pin 1.27mm Cortex-M Debug Adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10.
These fuses protect debug signals against overcurrent and cycle back to a conductive state
after the excessive current fades away.
The debug adapter connects to the target through one of the two 10-pin 1.27mm connectors.
Note that only one is to be connected to the target!
The one at the end of the cable is with a so called “strain relief” option (Samtec FFSD-05-01-N-
SR) and is the robust type when it comes to connecting and disconnecting it from the target
very often. This is the recommended connection connector to be used. However, the
connector is a bit wider and therefore the target must have a matching part populated.
Matching part on the target side is e.g. Samtec ESHF-105-01-L-D (full frame connector) or
Samtec FTSH-105-01-F-DV-K (connector without the frame at the side).
The second connector is 1cm away from the first one toward the blue box and is a “standard”
type (Samtec FFSD-05-01-N). It’s much less robust and is prone to fail if the cable is not handled
cautiously or just connected/disconnected too many times. This connector should be used
when the target doesn’t provide the matching target connector for the “strain relief” type

12
connector. Matching part on the target is Samtec SHF-105-01-L-D or Samtec FTSH-105-01-F-
DV-K (connector without the frame at the side).
Recommendation for the target side connector is the FTSH-105-01-F-DV-K connector, which
matches the connector with and without the strain relief option.

prone to fail

If the 10-pin 1.27 mm pitch ribbon cable gets damaged, it can be ordered as a spare part under
the ordering code IA10PIN10PIN127.
IC50116-2 with detached 10-pin 1.27mm pitch ribbon cable
Optionally, a longer ribbon cable can be ordered under the ordering code IA10PIN10PIN127-
CUST. A cable length must be specified at the order. Note that the optional length should be
reasonable (e.g. 10 cm) since the quality of electrical signals degrades with prolonging the
cable. iSYSTEM gives no assurance for BlueBox operation with this cable. The cable is meant to
be used only for boundary cases where BlueBox cannot be connected to the target hardware
through the standard debug adapter, for example due to the physical obstacles of the target
system. In such cases, operating the BlueBox at lower JTAG scan speeds and not using the trace
functionality at all, might be still an acceptable compromise. It’s up to the user to thoroughly
test and qualify the BlueBox operation using custom length ribbon cable and to determine
working winIDEATM settings for his system.

10-pin 1.27mm Custom Cortex D. Adapter
Ordering code
IC50116-CUST2
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to the Cortex-M
based target. It’s used to connect to the embedded target featuring a 20-pin 1.27mm target
debug connector with the custom Cortex-M pinout. Optionally connecting the RTCK or the
JTAG TRST to pin 7 (KEY pin otherwise) makes this debug adapter distinct from the IC50116-2
debug adapter.
The debug adapter connects to the 25cm 40-pin ribbon cable coming from the BlueBox and to
the target debug connector on the other side. Refer to the BlueBox User Manual for more
details on connecting the debug adapter.

10-pin custom Cortex-M pinout
This debug adapter features custom Cortex-M pinout. When connecting the BlueBox to
the new embedded target for the first time, double check that the debug adapter
pinout matches with the target debug connector. Note that a mismatch can result in a
hardware failure.

10-pin 1.27mm Cortex-M debug adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10.
These fuses protect debug signals against overcurrent and cycle back to a conductive state
after the excessive current fades away.
The debug adapter connects to the target via a 10-pin 1.27mm connector, for example SAMTEC
FFSD-05-01-N. A target should feature a matching part, for example SAMTEC: SHF-105-01-L-D-
TH.

20-pin Cortex-M pinout
Blue colored signals are parallel trace signals.
When connecting the BlueBox to the new embedded target for the first time, double
check that the debug adapter pinout matches with the target debug connector. Note
that a mismatch can result in a hardware failure.

20-pin 1.27mm Cortex-M Debug Adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10.
These protect debug signals against overcurrent and cycle back to a conductive state after the
excessive current fades away. Signals on pins 12, 14, 16, 18 and 20 are protected via 100 ohm
serial resistors.
The debug adapter connects to the target through one of the two 20-pin 1.27mm connectors.
Note that only one is to be connected to the target!
The one at the end of the cable is with a so called “strain relief” option (Samtec FFSD-10-01-N-
SR) and is the robust type when it comes to connecting and disconnecting it from the target
very often. This is the recommended debug tool connector to be used. However the connector
is a bit wider and therefore the target must have a matching part populated. Matching part on
the target side is e.g. Samtec ESHF-110-01-L-D (full frame connector) or Samtec FTSH-110-01-F-
DV-K (connector without the frame at the side).
The second connector is 1cm away from the first one toward the blue box and is a “standard”
type (Samtec FFSD-10-01-N). It’s much less robust and is prone to fail if the cable is not handled
cautiously or just connected/disconnected too many times. This connector should be used
when the target doesn’t provide the matching target connector for the “strain relief” type
connector. Matching part on the target is Samtec SHF-110-01-L-D or Samtec FTSH-110-01-F-
DV-K (connector without the frame at the side).
Recommendation for the target side connector is the FTSH-110-01-F-DV-K connector since it
matches with the connector with and without the strain relief option.
