NOTES:

X can be V
or V
for address or control pins except for RY/BY#, which is either V
OL
or V
OH
, or High Z or D
OUT
for data
pins depending on whether or not OE# is active.
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. 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 device manufacturer 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 erase, data program, or lock-block operations can only be completed successfully when V
PP
= V
PPH1
or
V
PP
= V
PPH2
.
While the WSM is running, RY/BY# 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
OL
while the WSM is busy performing various operations (for example, a Status Register read during a
program operation).
The 28F016XS shares an identical device identifier with the 28F016XD.
CE
0
–1
# at V
IL
is defined as both CE
0
# and CE
1
# low, and CE
0–1
# at V
IH
is defined as either CE
0
# or CE
1
# high.
10. Addresses are latched on the rising edge of CLK in conjunction with ADV# low. Address A
= 0 selects the even bank and
A
1
= 1 selects the odd bank, in both byte-wide mode and word-wide mode device configurations.
