Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector protection ver-
ification, 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 correspond-
ing programming algorithm. However, the autoselect codes can also be accessed in-system
through the command register.
When using programming equipment, the autoselect mode requires VID (11.5 V to 12.5 V) on
address pin A9. Address pins A6, A1, and A0 must be as shown in Table 8. In addition, when ver-
ifying sector protection, the sector address must appear on the appropriate highest order address
that are don’t care. When all necessary bits have been set as required, the programming equip-
ment may then read the corresponding identifier code on DQ7-DQ0.
To access the autoselect codes in-system, the host system can issue the autoselect command via
“Command Definitions” for details on using the autoselect mode.
Table 8. S29AL032D Autoselect Codes (High Voltage Method)
L = Logic Low = VIL, H = Logic High = VIH, SA = Sector Address, X = Don’t care.
Note: The autoselect codes may also be accessed in-system via command sequences. See Table 17 on page 38.
Sector Protection/Unprotection
The hardware sector protection feature disables both program and erase operations in any sector.
The hardware sector unprotection feature re-enables both program and erase operations in pre-
viously protected sectors.
