2048
BIT MASK PROGRAMMABLE
READ ONLY MEMORY
• Static MOS - No Clocks Required
• Simple Memory Expansion - Chip
Select Input Lead
• 24-Pin Dual-In-Line Hermetically
Sealed Ceramic Package
• Access
Time-1
p'sec Max.
• Fully Decoded,
256
x 8 Organization
• Inputs and Outputs TTL Compatible
• Three-State Output - OR-Tie
Capability
The
Intel@8302
is
a
fully
decoded 256 word
by
8
bit
metal mask ROM.
It
is
ideal
for
large volume produc-
tion runs
of
microcomputer systems initial.ly using the
8702A
erasable and electrically programmable ROM.
The
8302
has
the
same
pinning
as
the
8702A.
The 8302
is
entirely static - no clocks are required. Inputs and outputs
of
the 8302
are
TTL
compatible.
The
output
is
three-state
for
OR-tie capability. A separate chip select
input
allows
easy
memory expansion.
The 8302
is
packaged in a
24
pin dual-in-Iine hermetically
sealed
ceramic package.
The 8302
is
fabricated
with
p-channel silicon gate technology. This
low
threshold allows the design and
production
of
higher performance MOS circuits and provides a higher functional density on a
monolithic
chip than conventional MOS technologies.
