1. Address format A14-A0 (Hex),
Addresses A15 and A16 can be VIL or VIH, but no other value, for the Command sequence for SST39LF/VF200A.
Addresses A15, A16, and A17 can be VIL or VIH, but no other value, for the Command sequence for SST39LF/VF400A.
Addresses A15, A16, A17, and A18 can be VIL or VIH, but no other value, for the Command sequence for SST39LF/VF800A.
2. DQ15 - DQ8 can be VIL or VIH, but no other value, for the Command sequence
3. WA = Program word address
4. SAX for Sector-Erase; uses AMS-A11 address lines
BAX, for Block-Erase; uses AMS-A15 address lines
AMS = Most significant address
AMS = A16 for SST39LF/VF200A, A17 for SST39LF/VF400A and A18 for SST39LF/VF800A
5. The device does not remain in Software Product ID Mode if powered down.
6. With AMS-A1 =0; SST Manufacturer’s ID= 00BFH, is read with A0 = 0,
SST39LF/VF200A Device ID = 2789H, is read with A0 = 1.
SST39LF/VF400A Device ID = 2780H, is read with A0 = 1.
SST39LF/VF800A Device ID = 2781H, is read with A0 = 1.
7. Both Software ID Exit operations are equivalent
