They are used by the master device to select which of eight datssheet are to be accessed. The one below is set to have address 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.

Can somebody explain to me further the interest of having those pins? I found out that it have 3 pins A0,A1,A2 which as specified datadheet the datasheet are chip address input.

Here is a picture of I 2 C ‘s message frame. What are the address input pins used for in ds? Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line. Here’s what the data sheet says: Bence Kaulics 5, 10 23 Home Questions Tags Users Unanswered. Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices.

This is the address you set as it is described in the datasheet and in Andy aka ‘s answer. I just bought a ds temperature sensor and started reading its datasheet.

These bits are in effect the datasueet least significant bits of the slave address. Your device uses I 2 Cor often called 2-wire ddatasheet communication.
