PIN DESCRIPTIONS
8.1
Serial Data
This is a bi-directional pin used to transfer addresses
and data into and data out of the device. It is an open
drain terminal, therefore the SDA bus requires a pull-up
resistor to V
CC
(typically 10 K
for 100 kHz).
For normal data transfer SDA is allowed to change only
during SCL low. Changes during SCL high are
reserved for indicating the START and STOP condi-
tions.
8.2
SCL Serial Clock
This input is used to synchronize the data transfer from
and to the device.
8.3
WP
This pin must be connected to either V
SS
or V
CC
.
If tied to V
SS
, normal memory operation is enabled
(read/write the entire memory).
If tied to V
CC
, WRITE operations are inhibited. The
entire memory will be write-protected. Read operations
are not affected.
This feature allows the user to use the 24C01B/02B as
a serial ROM when WP is enabled (tied to V
CC
).
