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
The device select inputs (S
the first three bits of the 8-bit slave address. This
allows up to eight devices to share a common bus.
These inputs can be static or actively driven. If used
statically they must be tied to V
priate. If actively driven, they must be driven with
CMOS levels (driven to V

Write Protect (WP)
The Write Protect input controls the Hardware Write
Protect feature. When held LOW, Hardware Write
Protection is disabled. When this input is held HIGH,
and the WPEN bit in the Write Protect Register is set
HIGH, the Write Protect Register is protected,
preventing changes to the Block Lock Protection and
WPEN bits.
