The
IntelG!!
S04SH/S04SH-1/S035HL/S035HL-1 are totally self-sufficient, 8-bit parallel computers fabricated
on
single silicon chips using Intel's advanced N-channel silicon gate HMOS process.
The
S04SH
contains a 1 K X S program memory, a 64 X S RAM data memory,
27
I/O lines, and an S-bit
timer/counter in addition
to
on-board oscillator and clock circuits. For systems that require extra capability
the
S04SH
can
be
expanded using standard memories and MCS-SO™/MCS-85''' peripherals. The S035HL is
the equivalent
of
the
S04SH
without program memory and can
be
used with external ROM AND RAM.
To reduce development
problems to a minimum and provide maximum flexibility, a logically and functionally
pin compatible version
of
the
S04SH
with UV-erasable user-programmable EPROM program memory is avail-
able.
The
S74S
will emulate the
S04SH
up
to
6 MHz clock frequency with
minor
differences.
The
S04SH
is
fully
compatible with the
S04S
when operated at 6 MHz.
These microcomputers are designed
to
be
efficient controllers
as
well
as
arithmetic processors. They have
extensive
bit
handling capability
as
well
as
facilities
for
both binary and BCD arithmetic. Efficient use
of
progra'm memory results from
an
instruction set consisting mostly of single bit instructions and
no
in-
structions over 2 bytes in
length. .
