The 8052
microcontroller
is the
8051's
"big
brother."
It is a
slightly
more
powerful
microcontroller,
sporting
a number
of
additional
features
which
the
developer
may make
use of:
256
bytes
of
Internal
RAM
(compared
to
128
in
the
standard
8051).
A
third
16-bit
timer,
capable
of a
number
of
new
operation
modes
and
16-bit
reloads.
Additional
SFRs
to
support
the
functionality
offered
by
the
third
timer.
That's
really
about
all
there is
to the
difference
between
the 8051
and
8052.
The
remainder
of this
tutorial
will
explain
these
additional
features
offered
by the
8052,
and how
they are
used
within
user
programs.
Throughout
this
tutorial,
it is
assumed
that you
already
have
read the
8051
Tutorial
and have
a
thorough
understanding
of it.
