FT24C02A
(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.
