16-pin 2.54mm Renesas 78K0R
|
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas 78K0R based target featuring 16-pin 2.54mm pitch target debug connector with the 78K0R 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:

When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential 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 ‘Vcc’ pin (pin 4) 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 15, 10k ohm pull-up must be connected to this pin or the debugger may exhibit unpredictable behavior.
16-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 16-pin 2.54 mm connector, for example Yamaichi FAS-1601-2101-2-OBF. A target should feature a matching part, for example WÜRTH ELEKTRONIK 61201621621.
