Address format A14-A0 (Hex),Address A15 can be VIL or VIH, but no other value, for the Command sequence. 2. WA = Program Word address 3. SAX for Sector-Erase; uses AMS-A11 address lines BAX for Block-Erase; uses AMS-A15 address lines AMS = Most significant address AMS = A16 for SST32HF201/202 and A17 for SST32HF401/402 4. The device does not remain in Software Product ID mode if powered down. 5. With AMS-A1 = 0; SST Manufacturer’s ID = 00BFH, is read with A0 = 0, SST32HF201/202 Device ID = 2789H, is read with A0 = 1, SST32HF401/402 Device ID = 2780H, is read with A0 = 1. 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.)
