INPUT/OUTPUT DESCRIPTIONS
Amax–A0
=
Address inputs
Amax = A22 (128 Mb) or A21 (64 Mb)
DQ15–DQ0 =
Data input/output
CE#
=
Chip Enable input. Asynchronous
relative to CLK for the Burst mode.
OE#
=
Output Enable input. Asynchronous
relative to CLK for the Burst mode.
WE#
=
Write Enable input.
V
CC
=
Device Power Supply
(1.65 – 1.95 V).
V
IO
=
Input & Output Buffer Power Supply
(1.65 – 1.95 V).
V
SS
NC
=
Ground
=
No Connect; not connected internally
RDY
=
Ready output;
In Synchronous Mode, indicates the
status of the Burst read.
Low = data invalid. High = data valid.
In Asynchronous Mode, indicates the
status of the internal program and
erase function.
Low = program/erase in progress.
High Impedance = program/erase
completed.
CLK
=
CLK is not required in asynchronous
mode. In burst mode, after the initial
word is output, subsequent active
edges of CLK increment the internal
address counter.
AVD#
=
Address Valid input. Indicates to
device that the valid address is
present on the address inputs
(Amax–A0).
Low = for asynchronous mode,
indicates valid address; for burst
mode, causes starting address to be
latched.
High = device ignores address inputs
RESET#
=
Hardware reset input. Low = device
resets and returns to reading array
data
WP#
=
Hardware write protect input. At V
IL
,
disables program and erase functions
in the four highest and four lowest
sectors. At V
IH
, does not protect any
sectors.
ACC
=
At V
HH
, accelerates programming;
automatically places device in unlock
bypass mode. At V
IL
, locks all sectors.
Should be at V
IH
for all other
conditions.
