GND
Ground.
20
A1
RST
Hardware Reset (Active Low). This pin resets the device to the power default conditions. The reset
pin must be driven low for a minimum of 50 μs to be valid and to prevent false resets due to ESD
glitches or noise in the system. If not used, RST must be tied high with a pull-up resistor.
21
B1
VCC
Supply Voltage, 1.65 V to 3.6 V.
22
C1
SDA
I2C Serial Data. The open drain requires an external pull-up resistor.
23
D1
SCL
I2C Clock.
24
E1
INT
Processor Interrupt, Active Low, Open Drain. This pin can be pulled up to 2.7 V or 1.8 V for selection
flexibility in the processor GPIO supply group.
EP
N/A
EPAD
Exposed Pad. The exposed pad must be connected to ground.
