Description
Serial clock input
Data is latched on the rising edge of SCL and transferred the falling edge of SCL.
Serial input/output
This pin must be pulled up with a resistor because it is configured as an N-ch
open-drain pin for output.
Write protection input
A high on this input disables writing. A low on this input enables writing.
Address input
This pin is used to configure the slave address.
No connection (not connected internally)
1.8 to 5.5 V (for reading)
2.3 to 5.5 V (for writing)
0 V (GND)
