Device Addressing  
FIGURE 3-2: CONTROL BYTE  
ALLOCATION  
A control byte is the first byte received following the  
start condition from the master device. The control byte  
consists of a four bit control code; for the 24LC32 this  
is set as 1010 binary for read and write operations. The  
next three bits of the control byte are the device select  
bits (A2, A1, A0). They are used by the master device  
to select which of the eight devices are to be accessed.  
These bits are in effect the three most significant bits of  
the word address. The last bit of the control byte  
defines the operation to be performed. When set to a  
one a read operation is selected, and when set to a  
zero a write operation is selected. The next two bytes  
received define the address of the first data byte  
(Figure 3-3). Because only A11...A0 are used, the  
upper four address bits must be zeros. The most signif-  
icant bit of the most significant byte of the address is  
transferred first.

Following the start condition, the 24LC32 monitors the  
SDA bus checking the device type identifier being  
transmitted. Upon receiving a 1010 code and appropri-  
ate device select bits, the slave device outputs an  
acknowledge signal on the SDA line. Depending on  
the state of the R/W bit, the 24LC32 will select a read  
or write operation.
