14-pin 2.54mm Renesas RL78 Debug Adapter
Ordering code
IC50175
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas RL78
based target featuring 14-pin 2.54mm pitch target debug connector with the RL78 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:

14-pin RL78 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.
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 ‘VDD’ pin (pin 8) on the target debug
connector, which can be used to power the target. Maximum target current consumption
should not exceed 50mA.
Some RL78 devices may have two power supply pins (EVDD and VDD). Both must be connected
to the target debug connector, when the power is provided by the BlueBox.
The EVDD voltage from the pin 9 is used as a target reference voltage when ‘Vref’ option under
the ‘Debug I/O levels’ setting is checked in the ‘Hardware/Emulation Options/Hardware’ tab.
