... FUNCTIONAL DESCRIPTION The 24XX1025 supports a bidirectional 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as a transmitter and a device receiving data as a receiver. The bus must 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 24XX1025 works as a slave ...
Page 7
... BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition ...

... DEVICE ADDRESSING A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a 4-bit control code; for the 24XX1025, this is set as ‘1010’ binary for read and write operations. The next bit of the control byte is the block select bit (B0) ...
Page 9
... WRITE OPERATIONS 6.1 Byte Write Following the Start condition from the master, the control code (four bits), the block select (one bit), the Chip Select (two bits), and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. ...

... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete. (This feature can be used to maximize bus throughput.) Once the Stop condition for a Write command has been issued from the master, the device initiates the internally timed write cycle ...
Page 12
... READ OPERATION Read operations are initiated in the same way as write operations with the exception that the R/W bit of the control byte is set to one. There are three basic types of read operations: current address read, random read and sequential read. 8.1 ...
