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, 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# 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
OL
while the WSM is busy performing various operations (for example, a Status Register read during a
program operation).
The 28F016SV shares an identical device identifier (66A0H in word-wide mode, A0H in byte-wide mode) with the
28F016SA. See application note
AP-393 28F016SV Compatibility with 28F016SA
for software and hardware techniques to
differentiate between the 28F016SV and 28F016SA.
