Data Sheet
Toggle Bit (DQ 6 )
During the internal Program or Erase operation, any consecutive attempts to read DQ 6 will produce
alternating ‘0’s and ‘1’s, i.e., toggling between 0 and 1. When the internal Program or Erase operation
is completed, the toggling will stop. The device is then ready for the next operation. The Toggle Bit is
valid after the rising edge of fourth WE# pulse for Program operation. For Sector-, Block-, or Chip-
Erase, the Toggle Bit is valid after the rising edge of sixth WE# pulse. See Figure 21 for Toggle Bit tim-
ing diagram and Figure 35 for a flowchart.

Data Protection (PP Mode)
The SST49LF080A devices provide both hardware and software features to protect nonvolatile data
from inadvertent writes.
Hardware Data Protection
Noise/Glitch Protection: A WE# pulse of less than 5 ns will not initiate a Write cycle.
V DD Power Up/Down Detection: The Write operation is inhibited when V DD is less than 1.5V.
Write Inhibit Mode: Forcing OE# low, WE# high will inhibit the Write operation. This prevents inadver-
tent writes during power-up or power-down.
Software Data Protection (SDP)
The SST49LF080A provides the JEDEC approved Software Data Protection scheme for all data alter-
ation operation, 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 Program operation, provid-
ing optimal protection from inadvertent Write operations, e.g., during the system power-up or power-
down. Any Erase operation requires the inclusion of a six-byte load sequence.
