NOTES:
1. X can be VIH or VIL for address or control pins except for RY »/BY », which is either VOL or VOH.
2. RY »/BY » output is open drain. When the WSM is ready, Erase is suspended or the device is in deep power-down mode,
RY »/BY » will be at VOH if it is tied to VCC through a resistor. When the RY /» BY » at VOH is independent of OE » while a WSM
operation is in progress.
3. RP » at GND ± 0.2 V ensures the lowest deep power-down current.
4. A0 and A1 at VIL provide manufacturer ID codes in x8 and x16 modes respectively. A0 and A1, at VIH provide device ID
codes in x8 and x16 modes respectively. All other addresses are set to zero.
5. Commands for different Erase operations, Data Write operations of Lock-Block operations can only be successfully
completed when VPP = VPPH.
6. While the WSM is running, RY »/BY » in Level-Mode (default) stays at VOL until all operations are complete. RY »/BY » goes to
VOH when the WSM is not busy or in erase suspend mode.
7. RY »/BY » may be at VOL while the WSM is busy performing various operations. For example, a status register read during a
write operations.
