... Low-voltage design permits operation down to 1.8 volts with standby and active currents of only 3 A and 1 mA, respectively. The 24AA01 and 24AA02 also have page- write capability for bytes of data. The 24AA01 and 24AA02 are available in the standard 8-pin DIP and 8-pin surface mount SOIC packages. ...

... FUNCTIONAL DESCRIPTION The 24AA01/02 supports a bi directional 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, and a device receiving data as receiver. The bus has to be controlled by a master device which generates the serial clock ...

... Page Write R/W The write control byte, word address and the first data 1 byte are transmitted to the 24AA01/02 in the same way byte write. But instead of generating a stop con- dition the master transmits up to eight data bytes to the 24AA01/02 which are temporarily stored in the on-chip page buffer and will be written into the memory after the master has transmitted a stop condition ...

... Then the master issues the control byte again but with the R/W bit set to a one. The 24AA01/02 will then issue an acknowledge and transmits the eight bit data word. The master will not acknowledge the transfer but does generate a stop condition and the 24AA01/02 dis- continues transmission (Figure 7-2) ...
