1. Address format A10-A0 (Hex), Addresses A20-A11 can be VIL or VIH, but no other value (unless otherwise stated), for the command
sequence when in x16 mode.
When in x8 mode, Addresses A20-A12, Address A-1, and DQ14-DQ8 can be VIL or VIH, but no other value (unless otherwise stated), for
the command sequence.
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 A20-A11 address lines
BAX for Block-Erase; uses A20-A15 address lines
BKX for Bank Address; uses A20-A18 address lines
5. For SST36VF3203 the Security ID Address Range is: (x16 mode) = 100000H to 100087H,(x8 mode) = 100000H to 10010FH
SST ID is read at Address Range(x16 mode) = 100000H to 100007H (x8 mode) = 100000H to 10000FH
User ID is read at Address Range(x16 mode) = 100008H to 100087H (x8 mode) = 100010H to 10010FH
Lock status is read at Address 1000FFH (x16) or 1001FFH (x8). Unlocked: DQ3 = 1 / Locked: DQ3 = 0.
For SST36VF3204 the Security ID Address Range is:(x16 mode) = 000000H to 000087H, (x8 mode) = 000000H to 00010FH
SST ID is read at Address Range (x16 mode) = 000000H to 000007H (x8 mode) = 000000H to 00000FH
User ID is read at Address Range (x16 mode) = 000008H to 000087H (x8 mode) = 000010H to 00010FH
Lock Status is read at Address 0000FFH (x16) or 0001FFH (x8). Unlocked: DQ3 = 1 / Locked: DQ3 = 0
6. SIWA = Valid Word addresses for user Sec ID
For SST36VF3203 User ID valid Address Range is (x16 mode) = 100008H-100087H (x8 mode) = 100010H-10010FH.
For SST36VF3204 User ID valid Address Range is (x16 mode) = 000008H-000087H (x8 mode) = 000010H-00010FH.
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. A20, 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
SST36VF3203 Device ID = 7354H, is read with A0 = 1
SST36VF3204 Device ID = 7353H, 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”).
