Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or
left floating. Please make sure that GND is the first pad to be bonded. Pick-and-place and all component
assembly are recommended to be performed in ESD protected area.
Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The
coordinates may vary depending on sawing width and location, however, distances between pads are accurate.
