Figure 6. I2C Bus Protocol
Multibyte Write. For the Multibyte Write mode, the
MODE pin must be at VIH. The Multibyte Write
mode can be started from any address in the
memory. The master sends from one up to 4 bytes
of data, which are each acknowledged by the mem-
ory. The transfer is terminated by the master gen-
erating a STOP condition. The duration of the write
cycle is tW = 10ms maximum except when bytes
are accessed on 2 rows (that is have different
values for the 6 most significant address bits A7-
A2), the programming time is then doubled to a
maximum of 20ms. Writing more than 4 bytes in the
Multibyte Write mode may modify data bytes in an
adjacent row (one row is 8 bytes long). However,
the Multibyte Write can properly write up to 8
consecutive bytes as soon as the first address of
these 8 bytes is the first address of the row, the 7
following bytes being written in the 7 following bytes
of this same row.
Page Write. For the Page Write mode, the MODE
pin must be at VIL. The Page Write mode allows up
to 8 bytes to be written in a single write cycle,
provided that they are all located in the same ’row’
in the memory: that is the 5 most significant mem-
