PIN DESCRIPTIONS
Serial Clock (SCL)
The SCL input is used to clock all data into and out of the
device.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into and
out of the device. It is an open drain output and
may be wire-ORed with any number of open drain or open
collector outputs.
An open drain output requires the use of a pull-up
resistor. For selecting typical values, refer to the Pull-
Up Resistor selection graph at the end of this data
sheet.
Device Select (S
0
, S
1
, S
2
)
The device select inputs (S
0
,S
1
,S
2
) are used to set the
first three bits of the 8-bit slave address. This
allows up to eight X24165’s to share a common bus.
These inputs can be static or actively driven. If used
statically they must be tied to V
SS
or V
CC
as appropriate.
If actively driven, they must be driven with
CMOS levels (driven to V
CC
or V
SS
).
Write Protect (WP)
The write protect input controls the hardware write
protect feature. When held LOW, hardware write
protection is disabled and the X24165 can be written
normally. When this input is held HIGH, and the WPEN
bit in the write protect register is set HIGH, write
protection is enabled, and nonvolatile writes are
disabled to the selected blocks as well as the write
protect register itself.
