    Re: microcontrollers

    The strict difference is that a microprocessor is just the "core" processing unit (logic operations, interpretation of machine code), with some basic inputs and outputs. A microcontroller contains a microprocessor, and additional on-board peripherals (A/D converters, DACs, servo controllers, fancy interface units, etc.)

    In practice however, the line blurs a fair bit between self-declared microprocessors and self-declared microcontrollers (does, say, a floating point unit count as a peripheral?) But that's a semantics issue.
