Slave Address: After the master initiates a start condition, it must output the address of the device to be
accessed. The most significant four bits of the slave address are called the “device identifier.” The identifier
for the 24LLC16 is “1010B”. The next three bits (B2, B1, B0) are for block selection. They are used by the
master to select which of the blocks of internal memory (1 block=256 words) are to be accessed. (see Table
5-2 below.) These bits are in effect the three most significant bits of the word address
Read/Write: The final (eighth) bit of the slave address defines the type of operation to be performed. If the
R/
W
Function
bit is “1”, a read operation is executed. If it is “0”, a write operation is executed.
