Hello all,
I have a huge problem, with MPU-9250 chip.
Datasheet V1.0 (2015) states that for pins
2 -- 6, 14 -- 17 -> NC -> Not internally connected. May be used for PCB trace routing.
Datasheet V1.1 (2016) states the same:
2 -- 6, 14 -- 17 -> NC -> Not internally connected. May be used for PCB trace routing.
I have used pins 2 -- 6 to route the +3V3 power trace because I really need all the space I can get.
I have connected the center PAD to GND (as is custom to do so).
It turns out that pin 2, 5, 14 and 17 are connected to the center PAD!!!!! They are internally connected!!!!!
Now I have a short circuit on my PCB between +3V3 and GND.
How is this possible?
Am I the first to ever use the NC pins to route a trace?
Is this a production error? Or a hidden feature?
Any help or insight is greatly appreciated.
Thanks and regards,
Robert.
