The
Intel~
8049/8039/8039-6 Is a totally self-sufficient 8-bit parallel computer fabricated on a single silicon chip using
Intel's N-channel silicon gate
MOS
process.
The
8049
contains a
2K
x 8 program memory, a
128
x 8
RAM
data memory,
27
I/O lines, and an 8·blt timer/counter in
addition
to on board oscillator and clock circuits. For systems that require extra C;llpabillty, the
8049
can
be
expanded
using standard memories and
MCS-80™/MCS·85TM peripherals. The 8039
is
the equivalent
toan
8049
without program
memory. The
8039·6 is a lower speed (6
MHz)
version
of
the
8039.
.
To reduce development problems to a minimum and provide maximum flexibility,
two
Interchangeable pin-compatible
versions
of
this single component microcomputer exist: the
B049
with factory-programmed mask
ROM
program
memory for
low-cost high volume production, and the
8039
without program memory for use with external program
memories in prototype and preproduction systems.
This microprocessor is designed
to
be
an
efficient contl'oller
as
well as
an
arithmetic processor.
The
8049
has exten-
sive
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 two bytes
In
length.
