Functional operation of this device at these or any other conditions above those indicated in the operational sections of these specification is not implied or intended. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.

When OE = VIH, a write operation is started. Remarks: 1. H : VIH, L : VIL, : VIH or VIL, VID : 11.5 V to 12.5 V, VACC : 8.5 V to 9.5 V 2. If an address is held longer than the minimum read cycle time (tRC), the automatic sleep mode is set. 3. If WP (ACC)=VIL, sector 0,1,140, and 141 remain protected. If WP (ACC)=VIH, protection on sectors 0,1,140, and 141 depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection”. If WP (ACC)=VHH, all sectors will be unprotected. |
