Pin descriptions

2.2.1

A0, A1, A2

A2, A1, and A0 are selectable address pins for the 3 LSBs of the I2C interface address.

They can be set to VDD or GND to provide 8 unique address selections. These pins are

internally connected to the E2, E1, E0 (chip selects) of EEPROM.

2.2.2

VSS (ground)

This is the reference for the power supply. It must be connected to system ground.

2.2.3

SDA (open drain)

This is the Serial Data input/output pin.

2.2.4

SCL

This is the Serial Clock input pin.

2.2.5

EVENT (open drain)

This output pin is open drain and active-low, and functions as an Alert interrupt.

2.2.6

VDD (power)

This is the supply voltage pin, and ranges from +2.7 V to +3.6 V.
