Ordering code

IC50177

This debug and trace adapter is used to connect the iC5000 and the iC5700 BlueBox to Renesas RH850 based target featuring a 38-pin Mictor target connector with the RH850/F1H and RH850/F1KM-S4 Nexus pinout.

The debug adapter connects to the BlueBox through the two ribbon cables and to the target debug connector on the other side.

 

Warning_orange

When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure.

 

 

Jumper J1

The jumper J1 on the debug adapter is used to isolate (jumper removed) the target microcontroller EVTI input pin from the debugger, which can optionally control it.

 

Mictor 38-pin Renesas RH850 Nexus 16-bit Debug Adapter features resettable fuses on pins 9, 11, 12, 15, 17, 19, 21, 37. Fuse on pin 33 is not assembled. The fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away. All other signals are protected via 47 ohm serial resistor.

 

The debug adapter connects to the target via a 38-pin Mictor adapter, Tyco Electronics 5767055-1. A target should feature a matching part, for example Tyco Electronics 5767081-1 in SMT technology.

 

The following pinout is valid on the target side:
