20-Pin 2.54Mm Renesas V850 Debug Adapter - TASKING iSYSTEM IC50130 User Manual

20-pin 2.54mm Renesas V850 Debug Adapter

This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas (former
NEC) V850 based target featuring a 20-pin 2.54 mm pitch target debug connector with the
V850 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:

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.
20-pin 2.54mm V850 Debug 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 debug adapter connects to the target via a 20-pin 2.54 mm adapter, Yamaichi FAS-2001-
2101-2-OBF. A target should feature a matching part, for example WÜRTH ELEKTRONIK
61202021621.
