Q: What are the differences
between microprocessor and
micro controller.

Answer: The microprocessor is the
integration of a number of useful
functions into a single IC package.
These functions are: The ability to
execute a stored set of instructions
to carry out user defined tasks. The
ability to be able to access external
memory chips to both read and
write data from and to the
memory. Basically a
microcontroller is a device which
integrates a number of the
components of a
microprocessor system onto a
single microchip. So a
microcontroller combines onto the
same microchip : The CPU core
Memory (both ROM
and RAM) Some parallel digital I/ O
Essentially a microcontroller is
obtained by integrating the key
components of microprocessor
RAM ROM and Digital I/O onto the
same chip die. Modern
microcontroller s also contain a
wealth of other modules such as
Serial I/O Timers and Analogue to
Digital Converters.
