Write Operations
The Multibyte Write mode (only available on the
ST24/25C08 and the ST24C08R versions) is se-
lected when the MODE pin is at V
IH
and the Page
Write mode when MODE pin is at V
IL
. The MODE
pin may be driven dynamically with CMOS input
levels.
Following a START condition the master sends a
device select code with the RW bit reset to ’0’. The
memory acknowledges this and waits for a byte
address. The byte address of 8 bits provides ac-
cess to one block of 256 bytes of the memory. After
receipt of the byte address the device again re-
sponds with an acknowledge.
For the ST24/25W08 versions, any write command
with WC = 1 will not modify the memory content.
Byte Write.
In the Byte Write mode the master
sends one data byte, which is acknowledged by the
memory. The master then terminates the transfer
by generating a STOP condition. The Write mode
is independant of the state of the MODE pin which
could be left floating if only this mode was to be
used. However it is not a recommended operating
mode, as this pin has to be connected to either V
IH
or V
IL
, to minimize the standby current.
