DEVICE ADDRESSING
Following a start condition, the master must output the
address of the slave it is accessing. The first four bits
of the Slave Address Byte are the device type identifier
bits. These must equal “1010”. The next 3 bits are the
device select bits S
0
, S
1
, and S
devices to share a single bus. These bits are
compared to the S
0
, S
1
, and S
pins. The last bit of the Slave Address Byte defines the
operation to be performed. When the R/W bit is a one,
then a read operation is selected. When it is zero then
a program operation is selected. Refer to figure 4.
After loading the Slave Address Byte from the SDA
bus, the device compares the device type bits with the
value “1010” and the device select bits with the status
2
. This allows up to 8
2
device select input
of the device select input pins. If the compare is not
successful, no acknowledge is output during the ninth
clock cycle and the device returns to the standby mode.
The byte address is either supplied by the master or
obtained from an internal counter, depending on the
operation. When required, the master must supply the
two Address Bytes as shown in figure 4.
The internal organization of the E
by 32 bytes per sector. The sector address is partially
contained in the Address Byte 1 and partially in bits 7
through 5 of the Address Byte 0. The specific byte
address is contained in bits 4 through 0 of the Address
Byte 0. Refer to figure 4.
2
array is 512 sectors
