They only have address pins, which have to be tied to Vcc or ground for setting the address. Most ready to use boards with such chips already have pullup or pulldown resistors for this.

WebbI2C addressing uses 7 bits; however, many I2C data sheets specify 8-bit addresses, which includes the Read/Write bit. If we do not understand the translation between these 7- and 8-bit addresses, we will experience addressing issues because the Read/Write bit is set or cleared automatically by the PS or AXI I2C controller.
