PROMs are designed and tested for applications
requiring extended endurance. Inherent data
retention is greater than 100 years.
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
1
, S
2
)
The device select inputs (S
1
, S
2
) are used to set the first
and second bits of the 8-bit slave address. This
allows up to four X24645 devices 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 X24645 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.
