Note:

The MEMSIC logo’s arrow indicates the -X sensing

direction of the device.

The +Y sensing direction is rotated 90° away from the

+X direction.

Small circle indicates pin one (1).

ESD Compliance:

The MXR7900A/C/D sensor is in compliance with the following

ESD standards:

Human Body and 2500V per AEC-Q100-002 Rev. E

Machine Model and 250V per AEC-Q100-003 Rev. E

Mounting Orientation:

The package orientation of the MXR7900A/C/D does not affect

the performance of the sensor. The specifications as stated in page

2 remain the same.

Thus, if the sensor is installed with one of its axis of sensitivity in

the vertical plane, it detects accelerations in the Z-axis.
