The X24F128 is a CMOS SerialFlash Memory, inter-
nally organized 16K x 8. The device features a serial
interface and software protocol allowing operation on a
simple two wire bus.
Three device select inputs (S
0
鈥揝
2
) allow up to eight
devices to share a common two wire bus.
A Program Protect Register at the address location
FFFFh provides three program protection features:
Software Program Protect, Block Lock Protect, and
Hardware Program Protect. The Software Program
Protect feature prevents any nonvolatile writes to the
device until the PEL bit in the Program Protect
Register is set. The Block Lock Protection feature
allows the user to individually block protect four blocks
of the array by programming two bits in the Program
Protect Register. The Programmable Hardware
Program Protect feature allows the user to install the
device with PP tied to V
CC
, program the entire memory
array in circuit, and then enable the hardware program
protection by programming a PPEN bit in the Program
Protect Register. After this, selected blocks of the
array, including the Program Protect Register itself, are
permanently protected from being erased.
