 20-pin 2.54mm Renesas V850/RH850 Cable Adapter
Ordering code
IC50171
This adapter is used to connect the iC5000 / iC5500 / iC6000 development system to Renesas V850/RH850
based target. It connects to Debug/Trace module on one side and to the target debug connector on the other side.
It can be used for targets featuring 20-pin 2.54 pitch target debug connector with V850/RH850 pinout.
The following pinout is valid on the target side:

20-pin Renesas V850/RH850 target pinout
Note: 20-pin 2.54mm V850/RH850 Cable 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 adapter connects to the target via a 20-pin 2.54 mm connector (for example Yamaichi: FAS-2001-2101-2-
OBF). A target should feature a matching part (for example WÜRTH ELEKTRONIK: 612 020 216 21).
