“ First, solve the problem. Then, write the code. - John Johnson. A microprocessor is a chip that dependent on the chip of many function. A microcontroller is a single chip microcomputer that has everything in built. Microprocessors are often at least 16-bit, and typically 32-bit or 64-bit, though 8-bit still has a big market share. Microcontrollers  are typically 8-bit, but may be 4-, 16-, or 32-bit Microprocessors  run at speeds measured in hundreds of MHz Rapid movements of code & data between external memory & MP. Microprocessor instructions are mainly nibble or byte addressable. Microcontroller instructions are both bit addressable as well as byte addressable. Microprocessors  need special hardware to interface with sensors, motors, LEDs, etc. Microcontrollers are useful to interface with sensors and motors. Micro controllers are based on Harvard architecture where program memory and Data memory are separate Most of the microprocessors do not have power saving features. Most of the micro controllers have power saving modes like idle mode and power saving mode. This helps to reduce power consumption even Since components are internal, most of the operations are internal instruction, hence speed is fast. Microprocessors are not as easily worked with by a hobbyist. Microcontrollers are really nice for electronics hobbyists.
