1024 × 8-bit CMOS EEPROM with access protection
Figure 6 shows how the memory array is addressed when the slave address byte and
address field byte are sent. The master terminates the transfer by generating a STOP
condition. After this STOP condition, the Erase/Write (E/W) cycle starts and the I 2 C-bus is
free for another transmission. Up to 16 bytes of data can be written in the slave writing
sequence (E/W cycle).

Fig 6.
Auto-increment memory word address (2 byte write)
The general command encoding used by the serial port for EEPROM accesses is shown
in Figure 11 , where B[2:0] is the block number, P[2:0] is the page number within the block
and A[3:0] is the byte address within the page. Bits denoted as ‘X’ are ignored by the
device.
6.2.2 Page write
The PCA24S08 is capable of a 16-byte page write operation. It is initiated in the same
manner as the byte write operation. The master can transit 16 data bytes within one
transmission. After receipt of each byte, the PCA24S08 will respond with an acknowledge.
The typical E/W time in this mode is 5 ms.
After the receipt of each data byte, the four low-order bits of the word address are
internally incremented. The six high-order bits of the address remain unchanged. The
slave acknowledges the reception of each data byte with an ACK. The I 2 C-bus data
transfer is terminated by the master after the 16 th byte of data with a STOP condition.
After a write to the last byte in a page, the internal address is wrapped around to point to
the beginning of that page. If the master transmits more than 16 bytes prior to generating
the STOP condition, no acknowledge will be given on the 17 th (and following) data bytes
and the whole transmission will be ignored and no programming will be done. As in the
byte write operation, all inputs are disabled until completion of the internal write cycles.
After this STOP condition, the E/W cycle starts and the I 2 C-bus is free for another
transmission.
During the E/W cycle the slave receiver does not acknowledge if addressed via the
I 2 C-bus.
