11 / 34 page  ©2011 Silicon Storage Technology, Inc. DS25040A 05/11 11 16 Mbit Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 Data Sheet A Microchip Technology Company 4. With AMS-A5 = 0; Sec ID is read with A4-A0, SST ID is read with A4 = 0 (Address range = 00000H to 0000FH), User ID is read with A4 = 1 (Address range = 00010H to 0001FH). Lock Status is read with A7-A0 = 0000FFH. Unlocked: DQ3 = 1 / Locked: DQ3 =0. 5. Valid Byte Addresses for Sec ID are from 000000H-00000FH and 000020H-00002FH. 6. The device does not remain in Software Product ID Mode if powered down. 7. With AMS-A1 =0; SST Manufacturer ID = 00BFH, is read with A0 =0, SST39VF1681 Device ID = C8H, is read with A0 =1, SST39VF1682 Device ID = C9H, is read with A0 =1, AMS = Most significant address AMS =A20 for SST39VF1681/1682 8. Both Software ID Exit operations are equivalent 9. 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”). Table 7: CFI Query Identification String1 1. Refer to CFI publication 100 for more details.
