The page write mode allows up to 16 bytes to be written in a single write operation in the S-24C08C.
Its basic process to transmit data is as same as byte write, but it operates page write by sequentially receiving 8-
bit write data as much data as the page size has.
When the S-24C08C receives a 7-bit device address and a 1-bit read / write instruction code set to “0”, following a
start condition, it generates an acknowledge. And the S-24C08C receives 8-bit word address and responds with
an acknowledge. After the S-24C08C receives 8-bit write data and responds with an acknowledge, it receives 8-
bit write data corresponding to the next word address, and generates an acknowledge. The S-24C08C repeats
reception of 8-bit write data and generation of acknowledge in succession. The S-24C08C can receive as many
write data as the maximum page size.
Receiving a stop condition initiates a write cycle of the area starting from the designated memory address and
having the page size equal to the received write data.
In the S-24C08C, the lower 4 bits of the word address are automatically incremented every time when the S-
24C08C receives 8-bit write data. If the size of the write data exceeds 16 bytes, the upper 4 bits of the word
address and page address (P1, P0) remain unchanged, and the lower 4 bits are rolled over and the last 16-byte
data that the S-24C08C received will be overwritten.
