T7.1 1270

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”).
