... Low voltage design permits operation down to 2.5 volts with typical standby and active currents of only 5 A and 1 mA respectively. The 24LC04B/08B also has a page-write capability for bytes of data. The 24LC04B/08B is available in the standard 8-pin DIP and both 8-lead and 14-lead surface mount SOIC packages trademark of Philips Corporation ...

... 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 24LC04B/08B works as slave. Both, master and slave can operate as transmitter or receiver but the master device deter- mines which mode is activated ...

... Following the start condition, the 24LC04B/08B moni- tors the SDA bus checking the device type identifier being transmitted, upon a 1010 code the slave device outputs an acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24LC04B/ 08B will select a read or write operation. Control Operation ...

... Then the master issues the control byte again but with the R/W bit set to a one. The 24LC04B/ 08B 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 24LC04B/08B discontinues transmission (Figure 7-2) ...

... If tied WRITE operations are inhibited. The CC entire memory will be write-protected. Read operations are not affected. This feature allows the user to use the 24LC04B/08B as a serial ROM when WP is enabled (tied to V 8.4 A0, A1, A2 These pins are not used by the 24LC04B/08B. They may be left fl ...
