DESCRIPTION
The X24128 is a CMOS Serial E
organized 16K x 8. The device features a serial inter-
face and software protocol allowing operation on a
simple two wire bus.

Three device select inputs (S

) allow up to eight
A Write Protect Register at the highest address loca-
tion, FFFFh, provides three write protection features:
Software Write Protect, Block Lock Protect, and
Programmable Hardware Write Protect. The Software
Write Protect feature prevents any nonvolatile writes to
the device until the WEL bit in the Write Protect
Register is set. The Block Lock Protection feature
gives the user four array block protect options, set by
programming two bits in the Write Protect Register.
The Programmable Hardware Write Protect feature
allows the user to install the device with WP tied to
V
CC
, write to and Block Lock the desired portions of
the memory array in circuit, and then enable the In
Circuit Programmable ROM Mode by programming the
WPEN bit HIGH in the Write Protect Register. After
this, the Block Locked portions of the array, including
the Write Protect Register itself, are permanently
protected from being erased.
