7.2Random Read
Random read is a mode used when the data is read from arbitrary memory addresses.
To load a memory address into the address counter inside the EEPROM, first perform a dummy write according
to the following procedures:
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code “0”,
following the start condition signal, it outputs the acknowledgment signal.
Next, the EEPROM receives an 8-bit length word address and outputs the acknowledgment signal. Last, the
memory address is loaded into the address counter of the EEPROM.
the EEPROM receives the write data during byte or page writing. However, data reception is not performed
during dummy write.
The memory address is loaded into the memory address counter inside the EEPROM during dummy write. After
that, the master device can read the data starting from the arbitrary memory address by transmitting a new start
condition signal and performing the same operation as that in the “Current Read”.
That is, when the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code “1”,
following the start condition signal, it outputs the acknowledgment signal.
Next, 8-bit length data is output from the EEPROM, in synchronization with the SCL clock. The master device
does not output an acknowledgment signal and transmits the stop condition signal to finish reading.
