64 Mbit Multi-Purpose Flash Plus

SST39VF6401B / SST39VF6402B

Not Recommended for New Designs

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

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

SST39VF6401B Device ID = 236DH, is read with A0 = 1,

SST39VF6402B Device ID = 236CH, is read with A0 = 1.

AMS = Most significant address

AMS = A21 for SST39VF640xB

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.
