Note 1: One bus cycle is eight clock periods.

2: Address bits above the most significant bit of each density can be VIL or VIH.

3: One bus cycle is four clock periods in Dual Operation

4: 4-Kbyte Sector Erase addresses: use AMS-A12, remaining addresses are “don’t care” but must be set

either at VIL or VIH.

5: 64-Kbyte Block Erase addresses: use AMS-A16, remaining addresses are “don’t care” but must be set

either at VIL or VIH.

6: The Read STATUS Register is continuous with ongoing clock cycles until terminated by a low-to-high tran-

sition on CE#.

7: Device ID is read after three dummy address bytes. The Device ID output stream is continuous until ter-

minated by a low-to-high transition on CE#.

8: The instructions Release from Deep Power down and Read-ID are similar instructions (ABH). Executing

Read-ID requires the ABH instruction, followed by 24 dummy address bits to retrieve the Device ID.

Release from Deep Power-Down only requires the instruction ABH.
