the necessary tools for a microprocessor controller
The necessary tools for a microprocessor/controller
  • CPU: Central Processing Unit
  • I/O: Input /Output
  • Bus: Address bus & Data bus
  • Memory: RAM & ROM
  • Timer
  • Interrupt
  • Serial Port
  • Parallel Port
microprocessors
CPU for Computers

No RAM, ROM, I/O on CPU chip itself

Example:Intel’s x86, Motorola’s 680x0

Microprocessors:

General-purpose microprocessor

Many chips on mother’s board

Data Bus

CPU

General-Purpose Micro-processor

Serial COM Port

I/O Port

RAM

ROM

Timer

Address Bus

General-Purpose Microprocessor System

Microcontroller :

  • A smaller computer
  • On-chip RAM, ROM, I/O ports...
  • Example:Motorola’s 6811, Intel’s 8051, Zilog’s Z8 and PIC 16X

CPU

RAM

ROM

A single chip

Serial COM Port

I/O Port

Timer

Microcontroller

Microprocessor vs. Microcontroller

Microprocessor

  • CPU is stand-alone, RAM, ROM, I/O, timer are separate
  • designer can decide on the amount of ROM, RAM and I/O ports.
  • expansive
  • versatility
  • general-purpose
  • Microcontroller
  • CPU, RAM, ROM, I/O and timer are all on a single chip
  • fix amount of on-chip ROM, RAM, I/O ports
  • for applications in which cost, power and space are critical
  • single-purpose
