Data Sheet
Data# Polling (DQ 7 )
When the SST39WF1601/1602 are in the internal Program operation, any attempt to read DQ 7 will
produce the complement of the true data. Once the Program operation is completed, DQ 7 will produce
true data. Note that even though DQ 7 may have valid data immediately following the completion of an internal
Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in
subsequent successive Read cycles after an interval of 1 μs. During internal Erase operation, any attempt
to read DQ 7 will produce a ‘0’. Once the internal Erase operation is completed, DQ 7 will produce a ‘1’.
The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For
Sector-, Block- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#)
pulse. See Figure 7 for Data# Polling timing diagram and Figure 21 for a flowchart.
Toggle Bits (DQ6 and DQ2)
During the internal Program or Erase operation, any consecutive attempts to read DQ 6 will produce
alternating “1”s and “0”s, i.e., toggling between 1 and 0. When the internal Program or Erase operation
is completed, the DQ 6 bit will stop toggling. The device is then ready for the next operation. For Sector-
, Block-, or Chip-Erase, the toggle bit (DQ 6 ) is valid after the rising edge of sixth WE# (or CE#) pulse.
DQ 6 will be set to “1” if a Read operation is attempted on an Erase-Suspended Sector/Block. If Pro-
gram operation is initiated in a sector/block not selected in Erase-Suspend mode, DQ 6 will toggle.
An additional Toggle Bit is available on DQ 2 , which can be used in conjunction with DQ 6 to check
whether a particular sector is being actively erased or erase-suspended. Table 2 shows detailed status
bits information. The Toggle Bit (DQ 2 ) is valid after the rising edge of the last WE# (or CE#) pulse of
Write operation. See Figure 8 for Toggle Bit timing diagram and Figure 21 for a flowchart.
