DESCRIPTION
The X24325 is a CMOS 32,768 bit serial E
internally organized 4096 x 8. The X24325 features a
serial interface and software protocol allowing opera-
tion on a simple two wire bus.

A Write Protect Register at the highest address loca-
tion, FFFh, provides three new write protection
features: Software Write Protect, Block Write Protect,
and Hardware Write Protect. The Software Write
Protect feature prevents any nonvolatile writes to the
X24325 until the WEL bit in the write protect register is
set. The Block Write Protection feature allows the user
to individually write protect four blocks of the array by
programming two bits in the write protect register. The
Programmable Hardware Write Protect feature allows
the user to install the X24325 with WP tied to V
program the entire memory array in place, and then
enable the hardware write protection by programming
a WPEN bit in the write protect register. After this,
selected blocks of the array, including the write protect
register itself, are permanently write protected.
