20-pin 2.54mm Renesas V850/RH850 D. Adapter
Ordering code
IC50171
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas RH850
based target featuring a 20-pin 2.54 mm pitch target debug connector with the V850/RH850
pinout.
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.
The following pinout is valid on the target side:

20-pin V850/RH850 target 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.
20-pin 2.54mm V850/RH850 Debug Adapter features resettable fuses on all pins except for pin
16. These fuses protect debug signals against overcurrent and cycle back to a conductive state
after the excessive current fades away. A signal on pin 16 is protected via 100 ohm serial
resistor.
The debug adapter connects to the target via a 20-pin 2.54 mm connector, Yamaichi FAS-2001-
2101-2-OBF. A target should feature a matching part, for example WÜRTH ELEKTRONIK
61202021621.
