NOTES:
1. 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
.
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 V
OH
if it is tied to V
CC
through a resistor. When the RY
/BY
at V
OL
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. A
0
at V
IL
provide manufacturer ID codes. A
0
at V
IH
provide device ID codes. Device ID code = 23H.
All other addresses are set to zero.
5. Commands for different Erase operations, Data Write Operations, and Lock-Block operations can only
be successfully completed when V
PP
= V
PPH
.
6. 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.
7. RY
/BY
may be at V
OL
while the WSM is busy performing various operations. For example, a status register
read during a write operation.
