How to design PCB board

[hjhjhj]

Hi Daniel,

     Recently,my team is going to design a PCB board ,the MCU of which is MPC5643L. In order to use RAppID_bootloader in the simulink,I plan to design as follows.Firstly,adding a reset swicth in the PCB board.Secondly,FAB,ABS0 and ABS2 should be configurable because the Boot Mode is SCI when FAB is one and both ABS0 and ABS2 are zero,according to  the file" MPC5643LRM". Finally,configuring Pin B[2] and Pin B[2] for Serial Communication.

     Is there any question in my scheme?Can you give me some suggestions?

Thanks!

Hi hjhjhj‌,

The only suggestion i can make is to follow up the design rules from the Reference Board Schematics for this processor. You can find the motherboard design boards here: MPC564xL|32-bit MCU|Chassis-Safety|NXP 

You can find various schematics on NXP web site: e.g.: http://www.nxp.com/docs/en/user-guide/MPC5643LDMCBUG.pdf 

Best regards,
Daniel
