... Low voltage design permits operation down to 1.8 volts with standby and active cur- rents of only 3 A and 1 mA respectively. The 24AA04/ 08 also has a page-write capability for bytes of data. The 24AA04/08 is available in the standard 8-pin DIP and both 8-lead and 14-lead surface mount SOIC packages ...

... The bus has to be controlled by a master device which generates the serial clock (SCL), controls the bus access, and generates the START and STOP conditions, while the 24AA04/08 works as slave. Both master and slave can operate as transmitter or receiver, but the master device deter- mines which mode is activated ...

... The next three bits of the control byte are the block select bits (B2, B1, B0 don't care for both the 24AA04 and 24AA08 don't care for the 24AA04. They are used by the master device to select which of the two or four 256 word blocks of memory are to be accessed. These bits are in effect the most signifi ...

... Then the master issues the control byte again but with the R/W bit set to a one. The 24AA04/08 will then issue an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer but does generate a stop condition and the 24AA04/08 dis- continues transmission (Figure 7-2) ...
