Notes:
1. For a reSTART condition, or following a write cycle.
2. The minimum value delays the falling/rising edge of SDA away from SCL = 1 in order to avoid unwanted START and/or STOP
conditions.
3. In the Multibyte Write mode only, if accessed bytes are on two consecutive 8 bytes rows (6 address MSB are not constant) the
maximum programming time is doubled to 20ms.

The 4 most significant bits of the device select code
are the device type identifier, corresponding to the
I
2
C bus definition. For these memories the 4 bits
are fixed as 1010b. The following 3 bits identify the
specific memory on the bus. They are matched to
the chip enable signals E2, E1, E0. Thus up to 8 x
2K memories can be connected on the same bus
giving a memory capacity total of 16K bits. After a
START condition any memory on the bus will iden-
tify the device code and compare the following 3
bits to its chip enable inputs E2, E1, E0.
The 8th bit sent is the read or write bit (RW), this
bit is set to ’1’ for read and ’0’ for write operations.
If a match is found, the corresponding memory will
acknowledge the identification on the SDA bus
during the 9th bit time.
