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, block 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. RY/BY# at VOH is independent of OE# while a WSM
operation is in progress.
3. RP# at GND ± 0.2V 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 block erase operations, data program operations or 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
data program operation.
