7.1 Byte Write
The AT24CM02 supports the writing of a single 8-bit byte. Selecting a data word in the AT24CM02 requires 18-bit word address.
Upon receipt of the proper device address and the word address bytes, the EEPROM will send an Acknowledge. The device will then be ready to receive the 8-bit data word. Following receipt of the 8‑bit data word, the EEPROM will respond with an ACK. The addressing device, such as a bus host, must then terminate the write operation with a Stop condition. At that time, the EEPROM will enter an internally self-timed write cycle, which will be completed within tWR, while the data word is being programmed into the nonvolatile EEPROM. All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete.
