PIN DESCRIPTIONS
8.1
SDA Serial Address/Data Input/Output
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 pullup
resistor to V
CC
(typical 10K
for 100 kHz, 2 K
for
400 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 000-7FF).
If tied to V
CC
, WRITE operations are inhibited. The
entire memory will be write-protected. Read opera-
tions are not affected.
This feature allows the user to use the 24AA164 as a
serial ROM when WP is enabled (tied to V
CC
).
8.4
A0, A1, A2
These pins are used to configure the proper chip
address in multiple-chip applications (more than one
24AA164 on the same bus). The levels on these pins
are compared to the corresponding bits in the slave
address. The chip is selected if the compare is true.
Up to eight 24AA164s may be connected to the same
bus. These pins must be connected to either V
SS
or
V
CC
.
Note:
The level on A1 is compared to the inverse
of the slave address.
