1.1. PIC16 Microcontrollers

• MCU features

• Program execution

• RAM file registers

• Other PIC chips

The microcontroller unit (MCU) is now big, or rather small, in electronics. It is one of the most significant developments in the continuing miniaturization of electronic hardware. Now, even trivial products, such as a musical birthday card or electronic price tag, can include an MCU. They are an important factor in the digitization of analog systems, such as sound systems or television. In addition, they provide an essential component of larger systems, such as automobiles, robots, and industrial systems. There is no escape from microcontrollers, so it is pretty useful to know how they work.

The computer or digital controller has three main elements: ...
