10-pin 2.54mm Renesas 78K0 Debug Adapter
Ordering code
IC50174
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas 78K0
based target featuring 10-pin 2.54mm pitch target debug connector with the 78K0 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:

Signal Direction is described from the BlueBox perspective.
When connecting the BlueBox to a target for the first time, double check that the debug
adapter pinout matches the Target connector. A mismatch can result in a hardware
failure.
If the ‘Supply 5V to the target’ option is checked in the ‘Hardware/Emulation Options/CPU
Setup/Advanced’ tab, the debugger supplies 5V at the ‘5V OUT’ pin (pin 10) on the target debug
connector, which can be used to power the target. Maximum target current consumption should
not exceed 50mA.
If ‘RESET IN’ (target reset detection) from the microcontroller is not connected to the target
debug connector pin 1, 10k ohm pull-up must be connected to this pin or the debugger may
exhibit unpredictable behavior.
10-pin 2.54mm Renesas 78K0R Debug Adapter features resettable fuses on all connected pins.
These 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 2.54 mm connector, for example
Yamaichi FAS-1001-2101-2-OBF. A target should feature a matching part, for example WÜRTH
ELEKTRONIK 61201021621.
