The
Intel®
2316E
is
a
16,384-bit
static,
N-channel
MOS
read only
memory (ROM)
organized
as
2048 words by
8
bits.
Its
high
bit
density
is
ideal for large, non-volatile data storage applications
such
as
program
storage.
The
three-state outputs and
TTL
input/output
levels
allow
for direct interface with
common
system bus
structures.
The 2316E
single
+5V
power
supply
and 450
ns access
time
are
both
ideal
for
usage with high performance microcomputers
such
as
the
Intel
MCS™
-80
and
MCS™
-85
devices.
A
cost-effective
system development program may
be implemented by using
the
pin
compatible
Intel
2716 16K
UV
EPROM
for
prototyping
and
the lower cost 2616
PROM
and 2316E
ROM
for
production.
The
three
2316E programmable
chip selects
may
be defined by
the user
and
are fixed during the
masking
process. To
simplify the
conversion from
2716
prototyping
to
2316E
production,
it
is
recommended
that the
2316E programmable
chip
select logic levels be
defined the
same
as that
shown
in
the
below
data sheet pin configuration. This
pin configuration
and these
chip
select
logic levels
are the
same
as the
2716.
