MPU-9250 exposed pad and NC pins are connected

By timurkristof , 24 March 2017

Hey guys,

I've designed a PCB that has an MPU-9250. The datasheet (section 4.1) says that pins 2-6 and 14-17 are: "Not internally connected. May be used for PCB trace routing." So I used them for PCB routing. However I have discovered a nasty surprise.

It turns out that pins 2, 5, 14, 17 and the exposed pad are connected together internally in the chip. (I verified this using a multimeter.) This is not documented anywhere, so I'm wondering, is this a documentation error or do I have a faulty MPU-9250 chip?

Thanks in advance for your answer!
Best regards,
Timur
