PIN CONFIGURATION
PIN DESCRIPTIONS
Chip Select (
CS
)
The Chip Select input must be LOW to enable all read/
write operations.
CS
must remain LOW following a
Read or Write command until the data transfer is com-
plete.
CS
HIGH places the X25401 in the low power
standby mode and resets the instruction register. There-
fore,
CS
must be brought HIGH after the completion of
an operation in order to reset the instruction register in
preparation for the next command.
Serial Clock (SCK)
The Serial Clock input is used to clock all data into and
out of the device.
Serial Data In (SI)
SI is the serial data input.
Serial Data Out (SO)
SO is the serial data output. It is in the high impedance
state except during data output cycles in response to a
READ instruction.
AUTOSTORE Output (
AS
)
AS
is an open drain output which, when asserted indi-
cates V
CC
has fallen below the AUTOSTORE thresh-
old (V
ASTH
).
AS
may be wire-ORed with multiple open
drain outputs and used as an interrupt input to a micro-
controller or as an input to a low power reset circuit.
RECALL
RECALL
LOW will initiate an internal transfer of data
from E
2
PROM to the RAM array.
