DESCRIPTION
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.
