Microcontrollers for Power Over Ethernet

Microcontrollers are similar to processors in that they perform computational functions and carry out the instructions of a computer program. A microcontroller, however, is often used for embedded applications – as opposed to central processing units (CPUs) which are more commonly designed for general-purpose computing. Furthermore, microcontrollers are meant to reduce size and cost by including integrated peripherals such as flash memory, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), device drivers, transceivers for various communications protocols, and more.
