X24645 DEVICE OPERATION The X24645 supports a bidirectional bus oriented pro- tocol. The protocol defines any device that sends data onto the bus as a transmitter, and the receiving device as the receiver. The device controlling the transfer is a ...

X24645 Stop Condition All communications must be terminated by a stop condition, which is a LOW to HIGH transition of SDA when SCL is HIGH. The stop condition is also used to place the device into the standby power mode ...

X24645 DEVICE ADDRESSING Following a start condition the master must output the address of the slave it is accessing (see Figure 4). The next two bits are the device select bits. A system could have up to four X24645’s on ...

X24645 Page Write The X24645 is capable of a 32-byte page write operation initiated in the same manner as the byte write operation, but instead of terminating the write cycle after the first data word is transferred, the ...

X24645 READ OPERATIONS Read operations are initiated in the same manner as write operations with the exception that the R/W bit of the slave address is set HIGH. There are three basic read operations: current address read, random read and ...

X24645 Sequential Read Sequential reads can be initiated as either a current address read or random access read. The first byte is transmitted as with the other modes, however, the master now responds with an acknowledge, indicating it requires additional ...
