1. Address format A 14 -A 0 (Hex),
Addresses A MS -A 15 can be V IL or V IH , but no other value, for the Command sequence.
A MS = Most significant address
A MS = A 16 for SST39LF/VF010, A 17 for SST39LF/VF020, and A 18 for SST39LF/VF040
2. BA = Program Byte address
3. SA X for Sector-Erase; uses A MS -A 12 address lines
4. The device does not remain in Software Product ID mode if powered down.
5. With A MS -A 1 = 0; SST Manufacturer’s ID = BFH, is read with A 0 = 0,
SST39LF/VF010 Device ID = D5H, is read with A 0 = 1,
SST39LF/VF020 Device ID = D6H, is read with A 0 = 1,
SST39LF/VF040 Device ID = D7H, is read with A 0 = 1.
6. Both Software ID Exit operations are equivalent
