PIN DESCRIPTION
NAME NO.
A0 1 Address input 0. Connect directly to VCC or ground.
A1 2 Address input 1. Connect directly to VCC or ground.
RESET 3 Active low reset input. Connect to VCC or VDPUM(1) through a pull-up resistor, if not used.
SD0 4 Serial data 0. Connect to VDPU0(1) through a pull-up resistor.
SC0 5 Serial clock 0. Connect to VDPU0(1) through a pull-up resistor.
SD1 6 Serial data 1. Connect to VDPU1(1) through a pull-up resistor.
SC1 7 Serial clock 1. Connect to VDPU1(1) through a pull-up resistor.
GND 8 Ground
SD2 9 Serial data 2. Connect to VDPU2(1) through a pull-up resistor.
SC2 10 Serial clock 2. Connect to VDPU2(1) through a pull-up resistor.
SD3 11 Serial data 3. Connect to VDPU3(1) through a pull-up resistor.
SC3 12 Serial clock 3. Connect to VDPU3(1) through a pull-up resistor.
A2 13 Address input 2. Connect directly to VCC or ground.
SCL 14 Serial clock line. Connect to VDPUM(1) through a pull-up resistor.
SDA 15 Serial data line. Connect to VDPUM(1) through a pull-up resistor.
VCC 16 Supply power
(1) VDPUX is the pull-up reference voltage for the associated data line. VDPUM is the master I2C master reference voltage and VDPU0-VDPU3 are the slave channel reference voltages.
