14-pin Renesas RH850 (2.54mm) Debug Adapter
|
This debug adapter is used to connect the BlueBox to Renesas RH850 based target featuring a 14-pin 2.54 mm pitch target debug connector with the RH850 pinout.
The debug adapter connects to the 25 cm 40-pin ribbon cable coming from the BlueBox and to the target debug connector on the other side.
The following pinout is valid on the target side:

14-pin RH850 pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
14-pin 2.54mm RH850 Debug Adapter features resettable fuses on all pins except for pin 11. These fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away.
A signal on pin 11 is protected via 22 ohm serial resistor.
The debug adapter connects to the target via a 14-pin 2.54 mm connector, Yamaichi FAS-1401-2101-2-OBF. A target should feature a matching part, for example WÜRTH ELEKTRONIK 61201421621.
|
Make sure this adapter fits on your target connector - check Cross Table. |
