FEATURES
DESCRIPTION
The X24F064/032/016 is a CMOS SerialFlash
Memory Family, internally organized 8K/4K/2K x 8.
The family features a serial interface and software
protocol allowing operation on a simple two wire bus.
Device select inputs (S
0
, S
1
, S
2
) allow up to eight
devices to share a common two wire bus.
A Program Protect Register accessed at the highest
address location, provides three new programming
protection features: Software Programming Protection,
Block Lock Protection, and Hardware Programming
Protection. The Software Programming Protection
feature prevents any nonvolatile writes to the device
until the WEL bit in the program protect register is set.
The Block Lock
TM
Protection feature allows the user to
individually protect four blocks of the array by program-
ming two bits in the programming protect register. The
Programmable Hardware Program Protect feature
allows the user to install each device with PP tied to
V
CC
, program the entire memory array in place, and
then enable the hardware programming 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 programmed.
