NOTES:

X can be V
IH
or V
IL
for address or control pins except for RY/BY#, which is either V
OL
or V
OH
.
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 V
OH
if it is tied to V
CC
through a resistor. RY/BY# at V
OH
is independent of OE# while a WSM
operation is in progress.
RP# at GND ± 0.2V ensures the lowest deep power-down current.
A
and A
at V
provide manufacturer ID codes in x8 and x16 modes, respectively. A
0
and A
1
at V
IH
provide device ID
codes in x8 and x16 modes, respectively. All other addresses are set to zero.
Commands for different block erase operations, data program operations or lock-block operations can only be successfully
completed when V
PP
= V
PPH
.
While the WSM is running, RY/BY# in level-mode (default) stays at V
OL
until all operations are complete. RY/BY# goes to
V
OH
when the WSM is not busy or in erase suspend mode.
RY/BY# may be at V
while the WSM is busy performing various operations; for example, a Status Register read during a
data program operation.
