(for each clock signal transition to high, the master checks for a high level on sda.) standby mode power consumption is reduced in standby mode. the is24c02a/04a/08a/16a will enter standby mode: a) at power-up, and remain in it until scl or sda toggles; b) following the stop signal if a no write operation is initiated; or c) following any internal write operation.

(refer to figure 8. current address read diagram.) random address read selective read operations allow the master device to select at random any memory location for a read operation. the master device first performs a 'dummy' write operation by sending the start condition, slave address and byte address of the location it wishes to read. after the is24c02a/04a/08a/16a acknowledges the byte address, the master device resends the start condition and the slave address, this time with the r/ w bit set to one. the eeprom then responds with its ack and sends the data requested. the master device does not send an ack but will generate a stop condition. (refer to figure 9. random address read diagram.) sequential read sequential reads can be initiated as either a current address read or random address read. after the is24c02a/04a/08a/16a sends initial byte sequence, the master device now responds with an ack indicating it requires additional data from the is24c02a/04a/08a/ 16a. the eeprom continues to output data for each ack received. the master device terminates the sequential read operation by pulling sda high (no ack) indicating the last data word to be read, followed by a stop condition. the data output is sequential, with the data from address n followed by the data from address n+1,n+2 ... etc. the address counter increments by one automatically, allowing the entire memory contents to be serially read during sequential read operation. when the memory address boundary of 255, 511, 1023, or 2047 (depending on the device) is reached, the address counter ?rolls over? to address 0, and the device continues to output data. (refer to figure 10. sequential read diagram).
