PCA24S08
1024 × 8-bit CMOS EEPROM with access protection
6.2 Write operations
Write operations on the device can be performed only when WP is held LOW. When the
WP pin is held HIGH, content of the full memory is protected (Block 0 to Block 7,
APP registers, ID Page), and no write operation is allowed.
6.2.1 Byte/word write
Write command may be used to set the address for a subsequent Read command. For a
write operation, the PCA24S08 requires a second address field. The address field
associated with the two software selectable bits in the slave address is a word address
providing access to the 1024 bytes of memory, as shown in Figure 5 . Upon receipt of the
word address, the PCA24S08 responds with an acknowledge and awaits the next 8 bits of
data, again responding with an acknowledge. Word address is automatically incremented.
