address to 1010000b, A₀ = 1 sets the slave address to 1010001b.
2
SDA
Serial Data Input/Output. Bidirectional I²C data pin.
3
SCL
Serial Clock Input. I²C clock input.
4
V_CC
Power Input
5
GND
Ground
6
I/O3
Input/Output 3. I²C accessible bidirectional I/O pin.
7
I/O2
Input/Output 2. I²C accessible bidirectional I/O pin.
8
I/O1
Input/Output 1. I²C accessible bidirectional I/O pin.
9
I/O0
Input/Output 0. I²C accessible bidirectional I/O pin.
10
RST
Active-Low Reset Output. Open-drain CPU supervisor reset output.
