![]() ![]() In our example, we connect A0, A1, A2 directly to VCC in this way the device address is 1010111 (in general A0, A1, A2 identify the last three significant bits of the device address 1 0 1 0 A2 A1 A0) is 0x57 in Hexadecimal. When using a pull-up resistor, it recommends using 10kOhm or less. If this pin is left open/floating, it will be pulled down to the GND(internally). We can perform normal writing operations, by connecting it to GND When connected directly to VCC, all write operations to the memory are restricted. If these pins are left floating, the A2, A1, and A0 pins will be internally pulled down to GND. They must connect directly to GND or to VCC (hard wired). These pins allow you to customize the address of the device within the I2C bus.
