Table 2. S29AL004D Top Boot Block Sector Addresses
Table 3. S29AL004D Bottom Boot Block Sector Addresses
Note for Tables 2 and 3: Address range is A17:A-1 in byte mode and A17:A0 in word mode. See “Word/Byte Config-
uration” section.
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 VID (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 Tables 2 and 3). Table
4 shows the remaining address bits that are don’t care. When all necessary bits
have been set as required, the programming equipment may then read the cor-
responding identifier code on DQ7–DQ0.
