X24C01 PIN DESCRIPTIONS Serial Clock (SCL) The SCL input is used to clock all data into and out of the device. Serial Data (SDA) SDA is a bidirectional pin used to transfer data into and out of the device. It ...

X24C01 DEVICE OPERATION The X24C01 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 ...

Page 4

X24C01 Stop Condition All communications must be terminated by a stop con- dition, which is a LOW to HIGH transition of SDA when SCL is HIGH. The stop condition is also used by the X24C01 to place the device in ...

X24C01 WRITE OPERATIONS Byte Write To initiate a write operation, the master sends a start condition followed by a seven bit word address and a write bit. The X24C01 responds with an acknowledge, then waits for eight bits of data ...

Page 6

X24C01 Acknowledge Polling The disabling of the inputs can be used to take advan- tage of the typical 5 ms write cycle time. Once the stop condition is issued to indicate the end of the host’s write operation the X24C01 ...

X24C01 Sequential Read Sequential read is initiated in the same manner as the byte read. The first data byte is transmitted as with the byte read mode, however, the master now responds with an acknowledge, indicating it requires additional data. ...
