HY29F002
Command
Sequences
Legend:
X
=
Don’t
Care
PA
=
Address
of
the
data
to
be
programmed
RA
=
Memory
address
of
data
to
be
read
PD
=
Data
to
be
programmed
at
address
PA
RD
=
Data
read
from
location
RA
during
the
read
operation
SA
=
Sector
address
of
sector
to
be
erased
(see
Note
3
and
Table
1).
STAT
=
Sector
protect
status:
0x00
=
unprotected,
0x01
=
protected.
VSA
=
Address
of
the
sector
to
be
verified
(see
Note
3
and
T
able
1).
Notes:
1.
All
values
are
in
hexadecimal.
2.
All
bus
cycles
are
write
operations
unless
otherwise
noted.
3.
Address
is
A[10:0]
and
A[17:11]
are
don’t
care
except
as
follows:
For
RA
and
PA,
A[17:11]
are
the
upper
address
bits
of
the
byte
to
be
read
or
programmed.
For
SA,
A[17:13]
are
the
sector
address
of
the
sector
to
be
erased
and
A[12:0]
are
don’t
care.
For
VSA,
A[17:13]
are
the
address
of
the
sector
to
be
verified,
A[7:0]
=
0x02,
all
other
address
bits
are
don’t
care.
4.
The
Erase
Suspend
command
is
valid
only
during
a
sector
erase
operation.
The
system
may
read
and
program
in
non-erasing
sect
ors,
or
enter
the
Electronic
ID
mode,
while
in
the
Erase
Suspend
mode.
5.
The
Erase
Resume
command
is
valid
only
during
the
Erase
Suspend
mode.
6.
The
second
bus
cycle
is
a
read
cycle.
7.
The
fourth
bus
cycle
is
a
read
cycle.
8.
Either
command
sequence
is
valid.
The
command
is
required
only
to
return
to
the
Read
mode
when
the
device
is
in
the
Electron
ic
ID
command
mode
or
if
DQ[5]
goes
High
during
a
program
or
erase
operation.
It
is
not
required
for
