SINGLE CHIP MICROCOMPUTER
January/February, 1977
MOS SC/MP NOW OFFERED
Samples are now available of a new N-channel MOS version of the "SC/MP" 8-bit singlechip microprocessor that is twice as fast and
uses only one-fourth as much power as the Pchannel version.
Power consumption of SC/MP-ll is less than
200 mW, and only a single +5 V supply is required.

GI & ITT SIGN 6100 PACT
The 8048 single-chip microcomputer has
been introduced by Intel Corp. 's Microcomputer Systems Division. The new microcomputer
is one of three single-chip systems comprising the MCS-48 Microcomputer Systems family,
with a series of MCS-48 peripherals and a
line of programming and product development
tools. Intel plans to supply samples early
1977 and to begin production deliveries in
the spring.
The Intel 8048 and the 8748, a programmable version of the new microcomputer, are
the first general-purpose digital processing
and control systems to be integrated into a
single chip of semiconductor material., An
alternate design, the Intel 8035 microcomputer, provides addition system expansion options.
The 8048/8748 microcomputers can operate
as self contained systems with the addition
of a few simple parts such as the clock

General Instrument and ITT have signed a
licence agreement for ITT to second source
GI's 16-bit microprocessor, the CP6100. GI
will provide ITT with masks, hardware, and
software knowledge. There will be no payment
of money or transfer of technology from ITT
to GI. However, a provision for future exchange of technical improvements developed
by either company relating to the 1600 and
relevant software was spelled out.
ITT will produce the CPU at its Intermetall
operation in Freiburg, Germany.
PROCESS CONTROL INDUSTRY REPORT
The process control industry is eager to
tap new, sophisticated types of analytical
instruments--Fourier Transform Infrared, Mass
Spectrometry, Microwave Rotation 1 Spectrometry, and Raman Spectrophometry--for on-line
control applications, but their high cost has
deterred widespread use. Now microcomputers
promise to remedy that. "The instrument-control and data-handling capability that microcomputers can impart will render such instrument applications very cost effective," says
a new study by Frost & Sullivan.

crystal, timing resistors and capacitors, and
cable drivers.
The chip, itself, contains all functions
required for digital processing and control,
and all generally required I/O logic interfaces, latches and buffers. Basic subsystems
on the chip are:
o 8-bit central processor with an internally expandable register stack array, 96
instructions and 2.5 us instruction cycle.
o Basic peripherals and utilities, including
a programmable interval time/event
counter, two built-in priority interrupt
vectors, system clock generator and a
full set of timing and control utilities.
IK program storage in ROM and EPROM and
a 64-byte static RAM for read/write data
storage, registers and stack
o 32-line I/O subsystem with three lines for
interrupts, jump tests and extra clock
rate, and five system bus controls.
The processor can service inputs. and outputs on the same ports, set and reset bits,
and perform logical processing operations on
data right as the I/O ports.
The instruction set is designed to simplify
applications programming, enhance throughput
and increase the effective capacity of the
resident program memory. It includes numerous
branch instructions to make logic functions
easy to implement. Most instructions are single-byte.
The central processor can operate as a
byte processor (8-bit parallel binary processor), 4-bit binary or BCD arithmetic processor.
The number of registers and stack levels can
be modified by the programmer to suit the application.
The 8035 microcomputer adds program memory
size options to the basic system. Although it
does not contain a program memory, it can address and execute identical programs and is
plug-compatible with the 8048/8748.
The three microcomputers have the same addressing structure, which allows either in.ternal or peripheral memory to be addressed
without changing program addresses. This feature also facilitates product testing.
The
8048/8748 microcomputers can be programmed
for the applications and the same program memory space can be used to access a peripheral
containing special test programs.
The register array and the hardware stack,
which is used for program nesting, is integrated with data memory to provide more flexibility in processing capability.

Such potential power, inherent in micro
computers, accounts for some glowing projections in the F&S study. Shipments of industrial microcomputer equipment at $45 million in
1975 will soar to $1.2 billion by 1985, for
example, the study says. Here's another big,
broad application area: Industry is turning

this job"the 241-page study says. "In petroleum refining, for example, digital data communications can reduce the total installed
cost of a control system by as much as 30 percent."
Shipments of MPU's to indystry alone at
$22 million in 1975 will soar to $405 million
by 1985, the study projects. Memory sales at
$18 million in 1975 will climb to $570 million
by 1985. Meanwhile, interface and I/O components whole sales tallied a mere $5 million
last year and will reach $200 million.
The fastest growing market within the I/O
category, in turn, are data conversions devices-' analog/digital converters, data trans, mission devices, clock circuits, interrupt
circuits, I/O buffers, and so on. Their share
of the total I/O market at between 20% to 25%
in 1975 will increase to as much as 50% by
1985. "in this sector, non microprocessor manufacturers stand a good chance to achieve a
major share of the market," the study points
out. Analog Devices and Teledyne Semiconductor,
for example, have their own component manufacturing facilities, and as a result they could
achieve substantial penetration.
The st~dy also revealed:
oBit-slice microprocessors will become a
major growth area as its share of the CPU market, virtually nil currently, rises to 5% in
1977 and 20% in 1985. "As the superior processing capability of bipolar bit slice unit becomes appreciated by industrial designers, who
do not now understand the technology, its usage will grow at a rate faster than that of
MPU shipments overall," the study says.
o The 8-bit microprocessor, which accounted for 60% of all shipments by unit volume in
1975 will decline to a 35% market share by
1985. The 16-bit units on the other hand,
which has a 10% market share currently, will
snare a 45% market some 10 years out. Indeed,
shipments of 16-bit units at $2 million in
1975 are projected to soar to $183 million in
1985.
o The outlook for the 4-bit microprocessor
is entirely different. Shipments at $5 1/2
million in 1975 will inch up to $7 million by
1977, and then decline to a negligible amount
by the end of the decade. Current sales for
the 12-bit devices is less than $1 million and
accounts for no more than 3% of the total market. And though this figure will increase to 5% over the near term, the device,
"will begin to fade from the scene starting
about 1978."
Among end users,
the chemical industry
'will comprise the largest single industrial
market for microcomputers by 1985. Here, they
4
January/February, 1977
will be used as components in distributed control networks, data transmission networks,
and dedicated controllers, in addition to
their use in measuring instruments.
Microcomputer-based instruments will also
be widespread in the petroleum industry to account for a $110 million annual market by
1985. Another big growth area is food and
beverage industry whose trend to synthetic
foods is creating a need for more exciting
measurement and control techniques. Other big
end user categories include iron and steel,
aluminum, extractive metals, pulp and paper,
rubber and plastic, waste and water treatment,
and virtually every other process industry.
Discrete parts manufacturers, who currently comprise the industrial microcomputer's
largest end user market, will continue to
adopt the technology. Programmable logic controllers are increasingly acquiring greater
arithmetic capability, digital throughput,
and signal-processing for example, and such
a trend clearly points to an increased reli~
ance on microcomputers in the design of such
equipment, the study says. Digital Equipment
for example, has essentially stopped development work on its series 14 programmable logic
controllers and, instead, is pressing forward
on an LSI-II based product line.
I Microcomputer use does
face some hurdles
in industry, the study notes. Lack of product
standardization is one, for example. "This is
a principal concern among prospective users,"
the study finds. Report #431 106 Fulton St.,

LOW-COST DEVELOPMENT SYSTEM
Hardware and software designs that involve
the "SC/MP" 8-bit microprocessor can easily
be developed and quickly tested with a new
Low-Cost Development System (LCDS) now available from National Semiconductor.
According to Hashmukh Patel, marketing manager for the SC/MP microprocessor family, the
Low-Cost Development System is a simple controller configured with a SC/MP CPU card
plugged into one of four sockets in a card bus
on a 10 x 12" motherboard. Along with the CPU
card, the motherboard also contains a l6-key,
dual function hexidecimal keyboard, four keys
that control function, three control switches
and 6 digit hexidecimal LED display.
With the basic LCDS configuration alone,
control logic scratchpad memory and ROM-based
firmware on the motherboard allow the user to
alter the SC/MP registers and memory locaters,
run SC/MP programs in continous or single
instruction mode, and even operate with an
optional TTY using SC/MP DEBUG.
The LCDS features easy interfacing and expansion: four pre-wired 72-pin edge connector
sockets provide a plug-in interface for SC/MP
family cards, and also allow interconnection
of additional SC/MP applications hardware.
The built-in control and monitor functions
in the interface logic of the LCDS permit
transfer of control between resident firmware
and application programs generated by the user.
The firmware subroutines allow entry of software debug commands via the control and display panel or an optional teletype.
A 2k x 8 read/write memory card and a 4k x

SINGLE CHIP MICROCOMPUTER
The processor can use the programmable
timer to monitor and control I/O servicing delay, instead of software timing loops. In addition, the timer's 8-bit counter can be used
to count external operations, generate operating rates and perform other functions under
program control. Also, clock rates at different
frequencies are available for equipment control.
Two maskable, vectored priority interrupts
are built in. One can be used with the timer/
counter or for external inputs and the other
is dedicated to external inputs. Each vector
jumps the program to a specific memory address.
Other functions include the system clock
generator, reset control, single-step control,
and in the 8048, low-power standby. All three
microcomputers operate on a single +5V supply.
In addition, the 8748 has a 25 V input used
only during EPROM programming.
There are 32 I/O lines on each microcomputer.
Standard static RAMs, ROMs, or EPROMs interface with the bus through an 8212 I/O Port.
