12. 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.

21. Microprocessors and Microcontrollers
The microprocessor is a processor on one silicon
chip.
The microcontrollers are used in embedded
computing.
The microcontroller is a microprocessor with
added circuitry.

25. 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.

30. Choosing a microcontroller
Five major 8-bit microcontrollers:
• Freescale semiconductors (Motorola)
• Intel’s 8051
• Atmel’s AVR
• Zilog’s Z8
• PIC

31. Choosing a microcontroller
Three criteria in choosing a microcontroller:
1. Meeting the computing needs of the task at
hand efficiently and cost effectively.
2. Availability of software and hardware
development tools (Compilers, assemblers,
debuggers and emulators).
3. Wide availability and reliable sources of the
microcontroller.

32. Mechatronics and microcontrollers
Many technical processes and products in the are
of mechanical and electrical engineering show an
increasing integration of mechanics with electronic
and information processing.
Mechatronic = hardware + software
