Pin Functions
The slave address is assigned by connecting pins A0, A1 and A2 to the GND or to the V
One of the eight different slave address can be assigned to the S-24CS01A/02A by the combination of pins
A0, A1 and A2.
The slave address is assigned by connecting pins A1 and A2 to the GND or to the V
the four different slave address can be assigned to the S-24CS04A by the combination of pins A1 and A2.
The slave address is assigned by connecting the A2 pin to the GND or to the V
different slave address can be assigned to the S-24CS08A by A2 pin.
The given slave address, which is compared with the slave address transmitted from the master device, is
used to select the one among the multiple devices connected to the bus. The address input pin should be
connected to the GND or to the V
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
devices.
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.
The write protection is enabled by connecting the WP pin to the V
protection, connect the pin to the GND.
