Pin Functions

PIN DESCRIPTION
NO. NAME
1 A0 Address input 0. Connect directly to VCC or ground.
2 A1 Address input 1. Connect directly to VCC or ground.
3 RESET Active-low reset input. Connect to VCC or VDPUM(1) through a pull-up resistor, if not used.
4 INT0 Active-low interrupt input 0. Connect to VDPU0(1) through a pull-up resistor.
5 SD0 Serial data 0. Connect to VDPU0(1) through a pull-up resistor.
6 SC0 Serial clock 0. Connect to VDPU0(1) through a pull-up resistor.
7 GND Ground
8 INT1 Active-low interrupt input 1. Connect to VDPU1(1) through a pull-up resistor.
9 SD1 Serial data 1. Connect to VDPU1(1) through a pull-up resistor.
10 SC1 Serial clock 1. Connect to VDPU1(1) through a pull-up resistor.
11 INT Active-low interrupt output. Connect to VDPUM(1) through a pull-up resistor.
12 SCL Serial clock line. Connect to VDPUM(1) through a pull-up resistor.
13 SDA Serial data line. Connect to VDPUM(1) through a pull-up resistor.
14 VCC Supply power
(1) VDPUX is the pull-up reference voltage for the associated data line. VDPUM is the master I2C reference voltage while VDPU0 and VDPU1 are the slave channel reference voltages.
