I found out that it have 3 pins A0,A1,A2 which as specified in the datasheet are chip address input. The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations. The next 3 bits of the control byte are the device select bits A2, A1, A0. They are used by the master device to select which of eight devices are to be accessed. These bits are in effect the 3 least significant bits of the slave address.

Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line. Basically, if you de1621 several DS devices, you can set the hardware address for each and exclusively read up to 8 devices. The one below is set to have address A little addition to Andy aka ‘s answer. Your device uses I 2 Cor often called 2-wire serial communication.
In this communication protocol the master selects a slave by sending its address to the bus, and the specific slave identifies itself by this address. As you can see there is a Slave Address field which is 7 bit long.

Can somebody explain to me further the interest of having those pins? Null 4, 10 22 ChiPlusPlus 1 1 Here’s what the data sheet says: Andy aka k 10 Here is a picture of I 2 C ‘s message frame.
