„ Pin Functions
1. SDA (serial data input/output) pin
The SDA pin is used for bidirectional transfer of serial data. It consists of a signal input pin and an Nch
open-drain transistor output pin. Usually pull up the SDA line to V_CC via a resistor, and use it with other
open-drain or open-collector output devices connected in a wired-OR configuration.
2. SCL (serial clock input) pin
The SCL pin is used for serial clock input. It is capable of processing signals at the rising and falling
edges of the SCL clock input signal. Make sure the rise time and fall time conform to the specifications.
3. WP pin
The WP pin is used for write protection. When there is no need for write protection, connect the pin to
GND; when there is a need for write protection, connect the pin to V_CC.
