Data Protection (PP Mode)
The SST49LF080A devices provide both hardware and
software features to protect nonvolatile data from inadvert-
ent writes.
Hardware Data Protection
Noise/Glitch Protection: A WE# pulse of less than 5 ns will
not initiate a Write cycle.
V
inhibited when V
Write Inhibit Mode: Forcing OE# low, WE# high will inhibit
the Write operation. This prevents inadvertent writes during
power-up or power-down.

is less than 1.5V.

Software Data Protection (SDP)
The SST49LF080A provides the JEDEC approved Soft-
ware Data Protection scheme for all data alteration opera-
tion, i.e., Program and Erase. Any Program operation
requires the inclusion of a series of three-byte sequence.
The three-byte load sequence is used to initiate the Pro-
gram operation, providing optimal protection from inadvert-
ent Write operations, e.g., during the system power-up or
power-down. Any Erase operation requires the inclusion of
a six-byte load sequence.
