DESCRIPTION

NAME

WQFN

NO.

DSBGA

NO.

VIO

PWR

IO supply voltage (1.7 V to 5.5 V). This pin sets the I/O operating voltage for the serial

interface.

Thermal Pad

–

The thermal pad is located on the bottom-side of the WQFN package. The thermal pad

should be connected to any internal PCB ground plane using multiple vias for good

thermal performance.

(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
