1. FWH Mode uses consecutive Write cycles to complete a command sequence; PP Mode uses consecutive bus cycles to complete a

command sequence.

2. Address format A14-A0 (Hex), Addresses A21-A15 can be VIL or VIH, but no other value, for the Command sequence in PP Mode.

3. BA = Program Byte address

4. SAX for Sector-Erase Address

5. BAX for Block-Erase Address

6. Chip-Erase is supported in PP Mode only

7. SST Manufacturer’s ID = BFH, is read with A0=0,

With A19-A1 = 0; 49LF008A Device ID = 5AH, is read with A0 = 1.

8. The device does not remain in Software Product ID mode if powered down.

9. Both Software ID Exit operations are equivalent.
