1. Address format A14-A0 (Hex).

Addresses A15-A19 can be VIL or VIH, but no other value, for Command sequence for SST39VF1601/1602,

Addresses A15-A20 can be VIL or VIH, but no other value, for Command sequence for SST39VF3201/3202,

Addresses A15- A21 can be VIL or VIH, but no other value, for Command sequence for SST39VF6401/6402.

2. DQ15-DQ8 can be VIL or VIH, but no other value, for 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 = A19 for SST39VF1601/1602, A20 for SST39VF3201/3202, and A21 for SST39VF6401/6402

5. With AMS-A4 = 0; Sec ID is read with A3-A0,

SST ID is read with A3 = 0 (Address range = 000000H to 000007H),

User ID is read with A3 = 1 (Address range = 000010H to 000017H).

Lock Status is read with A7-A0 = 0000FFH. Unlocked: DQ3 = 1 / Locked: DQ3 = 0.

6. Valid Word-Addresses for Sec ID are from 000000H-000007H and 000010H-000017H.

7. The device does not remain in Software Product ID Mode if powered down.

8. With AMS-A1 =0; SST Manufacturer ID = 00BFH, is read with A0 = 0,

SST39VF1601 Device ID = 234BH, is read with A0 = 1,

SST39VF1602 Device ID = 234AH, is read with A0 = 1,

SST39VF3201 Device ID = 235BH, is read with A0 = 1,

SST39VF3202 Device ID = 235AH, is read with A0 = 1,

SST39VF6401 Device ID = 236BH, is read with A0 = 1,

SST39VF6402 Device ID = 236AH, is read with A0 = 1.

AMS = Most significant address

AMS = A19 for SST39VF1601/1602, A20 for SST39VF3201/3202, and A21 for SST39VF6401/6402

9. Both Software ID Exit operations are equivalent

10. If users never lock after programming, Sec ID can be programmed over the previously unprogrammed bits (data=1) using the Sec ID

mode again (the programmed “0” bits cannot be reversed to “1”). Valid Word-Addresses for Sec ID are from 000000H-000007H and

000010H-000017H.
