Address format A14-A0 (Hex), Addresses A15-AMS can be VIL or VIH, but no other value, for the Command sequence for SST29SF/VF020/040. AMS = Most significant address AMS = A17 for SST29SF/VF020 and A18 for SST29SF/VF040. 2. BA = Program Byte address 3. SAX for Sector-Erase; uses AMS-A7 address lines for SST29SF/VF020/040 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, SST29SF020 Device ID = 24H, is read with A0 = 1 SST29VF020 Device ID = 25H, is read with A0 = 1 SST29SF040 Device ID = 13H, is read with A0 = 1 SST29VF040 Device ID = 14H, is read with A0 = 1 6. Both Software ID Exit operations are equivalent |
