24LC08
8K-Bit Serial EEPROM
SEQUENTIAL READ OPERATION
Sequential read operations can be performed in two ways: as a series of current address reads or as random
address reads. The first data is sent in the same way as the previous read mode used on the bus. The next time,
however, the master responds with an ACK, indicating that it requires additional data. The 24LC08 continues
to output data for each ACK it receives. To stop the sequential read operation, the master does not respond
with an ACK, but instead issues a Stop condition.
Using this method, data is output sequentially with the data from address “n” followed by the data from “n+1”. The
word address pointer for read operations increments all word addresses, allowing the entire EEPROM to be read
sequentially in a single operation. After the entire EEPROM is read, the word address pointer “rolls over” and the
24LC08 continues to transmit data for each ACK it receives from the master (see Figure 3-14).
