„ Pin Functions
1. A2 (TEST) Pin
The slave address cannot be assigned in the S-24CS16A since the addressing function is removed.
The A2 pin should be connected to the GND.
2. SDA (Serial Data Input / Output) Pin
The SDA pin is used for bi-directional transmission of serial data. It consists of a signal input pin and an Nch open-
drain output pin.
The SDA line is usually pulled up to the V_CC, and OR-wired with other open-drain or open-collector output devices.
3. SCL (Serial Clock Input) Pin
The SCL pin is used for serial clock input. Since signals are processed at the rising or falling edge of the SCL clock
input signal, attention should be paid to the rising time and falling time to conform to the specifications.
4. WP (Write Protection Input) Pin
The write protection is enabled by connecting the WP pin to the V_CC. When there is no need for write protection,
connect the pin to the GND.
