Ordering code

IAMIC38SAM50MPC

Some targets based on NXP MPC5xxx / ST SPC5 family can feature a 50-pin Samtec ERF8 connector for the Nexus debug interface instead of the popular 38-pin Mictor connector. In this case use and connect the converter to the target first and then connect the 38-pin Mictor MPC5xxx Nexus 16-bit Debug Adapter to the converter.

 

Warning_orange

It has been noticed that the 50-pin Samtec ERF8 target connector may not always provide good mechanical stability in a vertical direction which can in worst case yield an unreliable debug connection. Special care must be taken when connecting this debug adapter to the target to prevent potential connection problems.

 

Warning_orange

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

 

The converter connects to the target via a 50-pin Samtec ERM8 connector, Samtec ERM8-025-01-L-D-EM2-TR. A target should feature a matching part, for example Samtec ERF8-025-05.0-L-DV.
