Chip Enable Input. This signal shall be
asynchronous relative to CLK for the
burst mode.
Output Enable Input. This signal shall
be asynchronous relative to CLK for
the burst mode.
Write enable. This signal shall be
asynchronous relative to CLK for the
burst mode.
Device ground
No connect. Pin not connected
internally
Ready Busy output
Clock Input that can be tied to the
system or microprocessor clock and
provides the fundamental timing and
internal operating frequency. CLK
latches input addresses in conjunction
with LBA# input and increments the
burst address with the BAA# input.
Load Burst Address input. Indicates
that the valid address is present on the
address inputs.
LBA# Low at the rising edge of the
clock latches the address on the
address inputs into the burst mode
Flash device. Data becomes available
t
rising edge of the same clock that
latches the address.
LBA# High indicates that the address
is not valid
Burst Address Advance input.
Increments the address during the
burst mode operation
