1. Address format A10-A0 (Hex), Addresses A19-A11 can be VIL or VIH, but no other value, for the command sequence when in x16 mode.
When in x8 mode, Addresses A19-A12, Address A-1 and DQ14-DQ8 can be VIL or VIH, but no other value, for the command sequence.
2. DQ15-DQ8 can be VIL or VIH, but no other value, for the command sequence
3. WA = Program word/byte address
4. SAX for Sector-Erase; uses A19-A11 address lines
BAX for Block-Erase; uses A19-A15 address lines
5. For SST36VF1601E,
SST ID is read with A3 = 0 (Address range = 00000H to 00007H),
User ID is read with A3 = 1 (Address range = 00010H to 00017H).
Lock Status is read with A7-A0 = 000FFH. Unlocked: DQ3 = 1 / Locked: DQ3 = 0.
For SST36VF1602E,
SST ID is read with A3 = 0 (Address range = C0000H to C0007H),
User ID is read with A3 = 1 (Address range = C0010H to C0017H).
Lock Status is read with A7-A0 = C00FFH. Unlocked: DQ3 = 1 / Locked: DQ3 = 0.
6. SIWA = User Security ID Program word/byte address
For SST36VF1601E, valid Word-Addresses for User Sec ID are from 00010H-00017H.
For SST36VF1602E, valid Word-Addresses for User Sec ID are from C0010H-C0017H.
All 4 cycles of User Security ID Program and Program Lock-out must be completed before going back to Read-Array mode.
7. The User Security ID Program Lock-out command must be executed in x16 mode (BYTE#=VIH).
8. The device does not remain in Software Product Identification mode if powered down.
9. A19 and A18 = BKX (Bank Address): address of the bank that is switched to Software ID/CFI Mode
With A17-A1 = 0;SST Manufacturer’s ID = 00BFH, is read with A0 = 0
SST36VF1601E Device ID = 734BH, is read with A0 = 1
SST36VF1602E Device ID = 734AH, is read with A0 = 1
10. Both Software ID Exit operations are equivalent
11. If users never lock after programming, User Sec ID can be programmed over the previously unprogrammed bits (data=1) using the
User Sec ID mode again (the programmed “0” bits cannot be reversed to “1”).
For SST36VF1601E, valid Word-Addresses for User Sec ID are from 00010H-00017H.
For SST36VF1602E, valid Word-Addresses for User Sec ID are from C0010H-C0017H.
