Data Sheet
5. With A MS -A 4 = 0; Sec ID is read with A 3 -A 0 ,
SST ID is read with A 3 = 0 (Address range = 000000H to 000007H),
User ID is read with A 3 = 1 (Address range = 000008H to 000087H).
Lock Status is read with A 7 -A 0 = 0000FFH. Unlocked: DQ 3 = 1 / Locked: DQ 3 = 0.
6. Valid Word-Addresses for Sec ID are from 000000H-000007H and 000008H-000087H.
7. The device does not remain in Software Product ID Mode if powered down.
8. With A MS -A 1 =0; SST Manufacturer ID = 00BFH, is read with A 0 = 0,
SST39VF801C/SST39LF801C Device ID = 233BH, is read with A 0 = 1, SST39VF802C/SST39LF802C Device ID =
233AH, is read with A 0 = 1,
A MS = Most significant address; A MS = A 18
9. Both Software ID Exit operations are equivalent
10. If users never lock after programming, Sec ID can be programmed over the previously unprogrammed bits (data=1)
using the Sec ID mode again (the programmed ‘0’ bits cannot be reversed to ‘1’). Valid Word-Addresses for Sec ID are
from 000000H-000007H and 000008H-000087H.
