CONTROL BYTE FORMAT

DEVICE ADDRESSING  
Read/Write Bit  
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 four-bit control code. For  
the 24AA024/24LC024/24AA025/24LC025, this is set  
as ‘1010’ binary for read and write operations. The next  
three bits of the control byte are the Chip Select bits  
(A2, A1, A0). The Chip Select bits allow the use of up

devices on the same bus and are used to select which  
device is accessed. The Chip Select bits in the control  
byte must correspond to the logic levels on the corre-  
sponding A2, A1 and A0 pins for the device to respond.  
These bits are in effect the three Most Significant bits of  
the word address.  
Start Bit  
5.1  
Contiguous Addressing Across  
Multiple Devices  
The last bit of the control byte defines the operation to  
be performed. When set to a one, a read operation is  
selected. When set to a zero, a write operation is  
selected. Following the Start condition, the 24AA024/  
24LC024/24AA025/24LC025 monitors the SDA bus  
checking the control byte being transmitted. Upon  
receiving a ‘1010’ code and appropriate Chip Select  
bits, the slave device outputs an Acknowledge signal  
on the SDA line. Depending on the state of the R/W bit,  
the 24AA024/24LC024/24AA025/24LC025 will select a  
read or write operation.  
The Chip Select bits A2, A1 and A0 can be used to  
expand the contiguous address space for up to 16K bits  
by adding up to eight 24AA024/24LC024/24AA025/  
24LC025 devices on the same bus. In this case, soft-  
ware can use A0 of the control byte as address bit A8,  
A1 as address bit A9 and A2 as address bit A10. It is  
not possible to sequentially read across device  
boundaries.
