Pin Functions
1. Address Input Pins (A0, A1, and A2)
Connect pins A0, A1, and A2 to the GND or the VCC, respectively, to assign slave addresses. There are
8 different ways to assign slave addresses in the S-24C01A and S-24C02A through a combination of
pins A0, A1, and A2, and 4 ways to assign them in the S-24C04A through a combination of pins A1 and
A2. When the input slave address coincides with the slave address transmitted from the master device,
1 device can be selected from among multiple devices connected to the bus. Always connect the
address input pin to GND or VCC and leave it unchanged.
2. SDA (Serial Data Input/Output) Pin
The SDA pin is used for bilateral transmission of serial data. It consists of a signal input pin and an Nch
open-drain transistor output pin.
Usually pull up the SDA line via resistance to the VCC, and use it with other open-drain or open-collector
output devices connected in a wired OR configuration.
3. 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 rising time and falling time conform to the
specifications.
4. TEST/WP Pin
The S-24C01A is not provided with a write protection (WP) function. The pin serves as the TEST pin.
So, always connect the pin to the GND.
In the S-24C02A and S-24C04A, this pin is used for write protection. When there is no need for write
protection, connect the pin to the GND; when there is a need for write protection, connect the pin to the
Vcc.
