DEFINITION OF EMBEDDED SYSTEMS
•Embedded system: is a system whose principal function is not computational, but which is controlled by a computer embedded within it.

PIC MICROCONTROLLERS
• Peripheral Interface Controller (PIC) was originally designed by General Instruments
• In the late 1970s, GI introduced PIC® 1650 and 1655 – RISC with 30 instructions.
• PIC was sold to Microchip
• Features: low-cost, self-contained, 8-bit, Harvard structure, pipelined, RISC, single accumulator, with fixed reset and interrupt vectors.

‘C’ implies CMOS technology; Complementary Metal Oxide Semiconductor
‘F’ insert indicates incorporation of Flash memory technology
Example: 16C84 was the first of its kind. It was later reissued as the 16F84, incorporating Flash memory technology. It was then reissued as 16F84A.

SUMMARY
• An embedded system is a product that has one or more computers embedded within it, which exercise primarily a control function.
• The embedded computer is usually a microcontroller: a microprocessor adapted for embedded control applications.
• Microcontrollers are designed according to accepted electronic and computer principles, and are fundamentally made up of microprocessor core, memory and peripherals.
• Microchip offers a wide range of microcontrollers, divided into a number of different families. Each family has identical central architecture and instruction set. However, common features also appear across all their microcontrollers.
• The Microchip 12F508 is a good microcontroller to introduce a range of features of microcontrollers in general and of PIC microcontrollers in particular.
