MPC5xxx/SPC5 14-pin 2.54mm Galvanic Isolation
Adapter
Galvanic isolation is used where two electric circuits must communicate, but their grounds
may be at different potentials. It is an effective method of breaking ground loops between the
two circuits. Galvanic isolation is also used for safety, preventing accidental current from
reaching ground through a person's body.
iSYSTEM Galvanic Isolation Adapters provide a basic isolation that withstands high voltages.
To prevent injury to personnel when dealing with potentially hazardous voltages it is
mandatory to have a second protection measure in place, in case the first insulation barrier
fails. This is termed double or, reinforced isolation. How should a double isolation be
implemented depends on the use-case or application setup.
It is your responsibility to check the local safety directives applicable to your company
and country to ensure that all requirements are met.
MPC5xxx / SPC5 14-pin 2.54 mm Galvanic Isolation Adapter is used to electrically isolate:
· iSYSTEM iC5700 BlueBox in conjunction with
o14-pin 2.54 mm MPC5xxx Debug Adapter (Ordering code IC50150) or
oMPC5x/SPC5x Aurora Active Probe MPC5x/SPC5x Aurora Active Probe (Ordering code
IC57150) + 14-pin 2.54 mm JTAG Converter (Ordering code IASAM34MPCPIN14)
from the embedded target.

VIORM is defined as the maximum repetitive peak voltage that the isolator can
withstand.
Make sure that the target side provides a reference voltage (VREF) for the adapter to
work properly.

Device overview
The top face of the Galvanic Isolation Adapter features:
A – DEBUG TOOL connector.
B – TARGET connector.
C– LED lights indicate power supply status.
If LEDs on the GI Adapter are OFF, immediately turn everything OFF!
The side face of the Galvanic Isolation Adapter features:
D – USB-C Power supply socket (PWR).
Use only original iSYSTEM USB-C Power supply for powering and connecting with the GI
Adapter, otherwise the primary functionality of the GI Adapter would be counteracted.

Connecting procedure
Do not use a Grounding wire between the BlueBox and the embedded target since it
would counteract the primary functionality of the Galvanic Isolation (GI) Adapter!
1. Make sure your hardware is powered OFF.
· Embedded Target
· BlueBox
· GI Adapter
2. Connect a Debug Adapter to the BlueBox. Refer to the BlueBox User Manual for more details
on connecting the Debug Adapter.
3. Connect the Debug Adapter to the GI Adapter.
4. Connect 1:1 Ribbon cable which is delivered along this package to the GI Adapter.
5. Connect 1:1 Ribbon cable to the embedded target.
6. Connect BlueBox, GI Adapter and Target to the power supply.
Use only original iSYSTEM USB-C Power supply for powering and connecting with the GI
Adapter, otherwise the primary functionality of the GI Adapter would be counteracted.
7. Power ON the hardware in the following order:
· BlueBox
· GI Adapter
· Target
If LEDs on the GI Adapter are OFF, immediately turn everything OFF!
