24LLC16
16K-Bit-Serial EEPROM
SEQUENTIAL READ OPERATION
Sequential read operations can be performed in two ways: current address sequential read operation, and
random address sequential read operation. The first data is sent in either of the two ways, current address byte
read operation or random address byte read operation described earlier. If the master responds with an ACK, the
24LLC16 continues transmitting data. If the master does not issue an ACK, generating a stop condition, the
slave stops transmission, ending the sequential read operation.
Using this method, data is output sequentially from address “n” followed by address “n+1”. The word address
pointer for read operations increments to 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 24LLC16
continues to transmit data for each ACK it receives from the master (see Figure 5-14).
