... A and 1 mA respectively. The 24AA164 also has a page-write capability for bytes of data. The 24AA164 is available in the standard 8-pin DIP and 8-lead surface mount SOIC packages. The three select pins, A0, A1, and A2, function as chip select inputs and allow up to eight devices to share a common bus, for up to 128K bits total system EEPROM ...

... During reads, a master must signal an end of data to the slave by not generating an acknowledge bit on the last byte that has been clocked out of the slave. In this case, the slave (24AA164) will leave the data line HIGH to enable the master to generate the STOP con- dition. ...

... When set to one a read operation is selected, when set to zero a write operation is selected. Following the start condition, the 24AA164 looks for the slave address for the device selected. Depending on the state of the R/W bit, the 24AA164 will select a read or write operation. Operation Control Code ...

... Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, first the word address must be set. This is done by sending the word address to the 24AA164 as part of a write operation. After the word address is sent, the master generates a start condition following the acknowledge ...
