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
1. Address format A
2. DQ
3. WA = Program word address
4. SA
5. For SST36VF3203 the Security ID Address Range is: (x16 mode) = 100000H to 100087H,(x8 mode) = 100000H to 10010FH
6. SIWA = Valid Word addresses for user Sec ID
7. The User Security ID Program Lock-out command must be executed in x16 mode (BYTE#=V
8. The device does not remain in Software Product Identification mode if powered down.
9. A
sequence when in x16 mode.
When in x8 mode, Addresses A

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
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.
With A
User Sec ID mode again (the programmed “0” bits cannot be reversed to “1”).
