INT
Output
Interrupt. Open-drain output; connect to GND
if not used
5
SCL
Input
I²C Serial Clock
6
SDA
I/O
I²C Serial Data
7
VDD
Supply
Chip Supply voltage (3 V); add a capacitor
GRM155R70J104KA01 (0402 X7R 0.1 µF
6.3 V) to GND
8
GND
Ground
Chip Ground; connect all ground pins
together
9
EN
Input
Enable input active high; setting to low forces
the device into shutdown and all memory
content is lost; connect to VDD if not used

GPIO1
I/O
General purpose input/output; default output
low; leave open if not used
11
GNDV
Ground
VCSEL Ground; connect all ground pins
together
12
VDDV
Supply
VCSEL Supply voltage (3 V); add a capacitor
GRM155R70J104KA01 (0402 X7R 0.1 µF
6.3 V) to GND
(1) SDA, SCL, INT and EN have no diode to any VDD supply. Therefore even with VDD=0 V they do not block the interrupt
line or I²C bus.
(2) GPIO0 and GPIO1 are push/pull output and have a diode to VDD; therefore if VDD is not powered, GPIO0 and GPIO1
should not be driven from outside.
