Am29F080B Autoselect Codes (High Voltage Method)
Legend:
L = Logic Low = V
IL
, H = Logic High = V
IH
, SGA = Sector Group Address, X = Don’t care.
Note:
The system may also autoselect information in-system via the command register. See Table 5.
Sector Group Protection/Unprotection
The hardware group sector protection feature dis-
ables both program and erase operations in any sec-
tor group. Each sector group consists of two adjacent
sectors. Table 4 shows how the sectors are grouped,
and the address range that each sector group con-
tains. The hardware sector group unprotection fea-
ture re-enables both program and erase operations in
previously protected sector groups.
Sector group protection/unprotection must be imple-
mented using programming equipment. The procedure
requires a high voltage (V
ID
) on address pin A9 and the
control pins. Details on this method are provided in a
supplement, listed in publication number 19945. Con-
tact an AMD representative to obtain a copy of the ap-
propriate document.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sector groups at its factory prior to shipping the device
through AMD’s ExpressFlash Service. Contact an
AMD representative for details.
It is possible to determine whether a sector group is
protected or unprotected. See “Autoselect Mode” for
details.
Table 4.
Sector Group Addresses
Temporary Sector Group Unprotect
This feature allows temporary unprotection of previ-
ously protected sector groups to change data in-sys-
tem. The Sector Group Unprotect mode is activated
by setting the RESET# pin to V
ID
. During this mode,
formerly protected sector groups can be programmed
or erased by selecting the sector group addresses.
Once V
ID
is removed from the RESET# pin, all the
previously protected sector groups are
protected again. Figure 1 shows the algorithm, and
the Temporary Sector Group Unprotect diagram
shows the timing waveforms, for this feature.
