7 / 17 page ACE24AC02A1 Two-wire Serial EEPROM VER 1.4 7 (C) Random Read Random read is a two-steps process. The first step is to initialize the internal address counter with a target read address using a “dummy write” instruction. The second step is a current address read. To initialize the internal address counter with a target read address, the micro-controller issues a start bit first, follows by a valid device address with the read/write bit (8 th ) set to “0”. The EEPROM will then acknowledge. The micro-controller will then send the address word. Again the EEPROM will acknowledge. Instead of sending a valid written data to the EEPROM, the micro-controller performs a current address read instruction to read the data. Note that once a start bit is issued, the EEPROM will reset the internal programming process and continue to execute the new instruction which is to read the current address.
