Pin Functions

1. Address input pins (A0, A1 and A2)

The slave address is assigned by connecting pins A0, A1 and A2 to the GND or to the VCC respectively. 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 VCC respectively. One of the four

different slave address can be assigned to the S-24CS04A by the combination of pins A1 and A2.

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 VCC.

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 VCC, 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 protect input) pin

The write protect is enabled by connecting the WP pin to the VCC. When there is no need for write protect, connect the

pin to the GND.



Initial Delivery State

Initial delivery state of all addresses is "FFh".
