viously protected sector groups. This function can
be implemented either in-system or by using pro-
gramming equipment. Note that to unprotect any
sector, all unprotected sector groups must first be
protected prior to the first sector unprotect write
cycle.
Also, the unprotect procedure will cause
all sectors to become unprotected, thus, sector
groups that require protection must be protected
again after the unprotect procedure is run.
This procedure requires V
ID
on the RESET# pin
and uses standard microprocessor bus cycle tim-
ing to implement sector unprotection. The flow
chart in Figure 4 illustrates the algorithm.
Temporary Sector Unprotect Operation
This feature allows temporary unprotection of pre-
viously protected sector groups to allow changing
the data in-system. Temporary Sector Unprotect
mode is activated by setting the RESET# pin to
V
ID
. While in this mode, formerly protected sec-

tors can be programmed or erased by invoking
the appropriate commands (see Device Com-
mands section). Once V
ID
is removed from RE-
SET#, all the previously protected sector groups
are protected again. Figure 5 illustrates the algo-
rithm.
NOTE:
If WP#/ACC = V
IL
, the boot sectors remain pro-
tected.
Electronic ID Operation (High Voltage Method)
The Electronic ID mode provides manufacturer
and device identification, sector protection verifi-
cation and Sec
2
region protection status through
identifier codes output on DQ[15:0]. This mode is
intended primarily for programming equipment to
automatically match a device to be programmed
with its corresponding programming algorithm.
Two methods are provided for accessing the Elec-
tronic ID data. The first requires V
ID
on address
pin A[9], with additional requirements for obtain-
