7 Debug Options available
The MPC5746R production device (PD) supports a standard 14-pin JTAG connector. A development 
solution is provided by the 292BGA emulation device (ED). The ED supports a high-speed serial Nexus 
trace port that utilizes a Xilinx Aurora interface as the transport mechanism. The ED is mounted to a Trace 
Adapter that allows the customer to install it on production hardware for development support. This ED 
solution may be ordered through your NXP representative. 
NOTE
It is possible that “keep-out” areas may be required by some debug tools. 
Consult the preferred debug tool vendor to determine any area that must 
remain clear around the debug connector. Also note that the ED solution 
may require a small keep out area on the customer PCB to accommodate the 
adapter and device. Refer to the drawings provided with the MPC5746R ED 
system.
7.1 MPC5746R JTAG connector
Figure 16 shows the pin-out of the recommended JTAG connector to support MPC5746R device. The 
recommended connector for the target system is Tyco part number 2514-6002UB.

7.2 MPC5746R high-speed Nexus serial trace connector
For high speed Nexus Aurora trace applications, the Samtec™ ERF8 Series connector is recommended in 
the IEEE-ISTO 5001™-2012 standard. For the MPC57xx family, the 17 position (34 pins) connector is 
recommended. The part number of the Samtec connectors are shown in the following table.
