The Intel
M80481M8748JM8035L
are totally self-sufficient 8-bit parallel computers fabricated on single silicon chips using
Intel's N-Channel silicon gate MOS process_
The M8048 contains
an
8-bit
CPU,
a 1 K x 8 program memory, a 64 x 8
RAM
data memory,
27

lines, and
an
8-bit timerl

to
on-board oscillator and

F.ro
systems that require extra capability, the M8048 can be
expanded using standard memories and
MCS-80™IMCS-85TM
peripherals_ The M8035L is the equivalent
of
an
M8048
without
program memory, and has the RAM power. down mode
of
the
M8048_
To reduce development problems
to
a min-
Imum
and provide maximum flexibility, three Interchangeable pin-compatible' versions
of
this
single component micro-
computer exist: the M8748 with user-programmable and erasable
EPROM
program memory for prototype and prepro-
duction systems, the M8048 with factory-programmed mask
ROM
program memory
for
low cost, high volume production,
and the M8035L without program memory
for
use with external program memories_
This microprocessor is designed
to
be
an
efficient controller as well as
an
arithmetic processor. The M8048 has extensive
bit handling capability as
well as facilities
for
both binary and BCD arithmetic. Efficient use of program memory results
from
an
instruction set consisting mostly
of
single byte instructions and no Instructions over 2 bytes in length.
'Vee is used
to
program the M8748 and used for low power standby on the M8048I8035L.
