HT24LC02 Rev. 1.70 6 May 6, 2010 · Random read A random read requires a dummy byte write sequence to load in the data word address which is then clocked in and acknowledged by the EEPROM. The microcontroller must then generate another start con- dition. The microcontroller now initiates a current ad- dress read by sending a device address with the read/write select bit high. The EEPROM acknowl- edges the device address and serially clocks out the data word. The microcontroller should respond with a ²no ACK² signal (high) followed by a stop condition. (refer to Random read timing). · Sequential read Sequential reads are initiated by either a current ad- dress read or a random address read. After the microcontroller receives a data word, it responds with an acknowledgment. As long as the EEPROM receives an acknowledgment, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word address will roll over and the sequential read continues. The sequential read operation is terminated when the microcontroller responds with a ²no ACK² sig- nal (high) followed by a stop condition.
