8.0
The descriptions of the pins are listed in Table 8-1.
TABLE 8-1:
8.1
The A0, A1 and A2 pins are not used by the 24XX01.
They may be left floating or tied to either V
8.2
The SDA input is a bidirectional pin used to transfer
addresses and data into and out of the device. Since
it is an open-drain terminal, the SDA bus requires a
pull-up resistor to V
2 k
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating Start and Stop conditions.

The SCL input is used to synchronize the data transfer
to and from the device.

(read/write the entire memory 00-7F).
If tied to V
memory will be write-protected. Read operations are
not affected.
