... IS24C32A/B IS24C64A/B DEVICE OPERATION IS24CXX features serial communication and supports a bi- directional 2-wire bus transmission protocol called I 2-WIRE BUS The two-wire bus is defined as a Serial Data line (SDA), and a Serial Clock line (SCL). The protocol defines any device that sends data onto the SDA bus as a transmitter, and the receiving devices as receivers ...

... IS24C32A/B IS24C64A/B DEVICE ADDRESSING The Master begins a transmission by sending a Start condition. The Master then sends the address of the particular Slave devices it is requesting. The Slave device (Fig. 5) address is 8 bits. The four most significant bits of the Slave address are fixed as 1010 for the IS24CXX. ...
