1. Address format A14-A0 (Hex), Addresses AMS-A15 can be VIL or VIH, but no other value, for the Command sequence.

AMS = Most significant address

AMS = A16 for SST39SF010A, A17 for SST39SF020A, and A18 for SST39SF040

2. BA = Program Byte address

3. SAX for Sector-Erase; uses AMS-A12 address lines

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

5. With AMS-A1 = 0; SST Manufacturer’s ID = BFH, is read with A0 = 0,

SST39SF010A Device ID = B5H, is read with A0 = 1

SST39SF020A Device ID = B6H, is read with A0 = 1

SST39SF040 Device ID = B7H, is read with A0 = 1

6. Both Software ID Exit operations are equivalent

Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maximum

Stress Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation

of the device at these conditions or conditions greater than those defined in the operational sections of this data

sheet is not implied. Exposure to absolute maximum stress rating conditions may affect device reliability.)
