Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector
protection verification, through identifier codes output on DQ7–DQ0. This mode
is primarily intended for programming equipment to automatically match a device
to be programmed with its corresponding programming algorithm. However, the
autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires V
ID
(11.5 V
to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in
Table 4
. In addition, when verifying sector protection, the sector address must
appear on the appropriate highest order address bits (see
Table 2, on page 13
and
Table 3, on page 14
).
Table 3
shows the remaining address bits that are don’t
care. When all necessary bits are set as required, the programming equipment
may then read the corresponding identifier code on DQ7-DQ0.
To access the autoselect codes in-system, the host system can issue the autose-
lect command via the command register, as shown in
Table 10, on page 31
and
Table 11, on page 32
. This method does not require V
ID
. See
“Command Defini-
tions” on page 23
for details on using the autoselect mode.
Table 4.
Autoselect Codes (High Voltage Method)
L = Logic Low = V
IL
, H = Logic High = V
IH
, SA = Sector Address, X = Don’t care.
Note:
The autoselect codes may also be accessed in-system via command sequences. See
Table 10, on page 31
and
Table 11, on page 32
.
Sector Protection/Unprotection
The hardware sector protection feature disables both program and erase opera-
tions in any sector. The hardware sector unprotection feature re-enables both
program and erase operations in previously protected sectors.
The device is normally shipped with all sectors unprotected. However, the Ex-
pressFlash Service offers the option of programming and protecting sectors at
