  1. EE290: Introduction to Microcontrollers Spring 2002 Martin D. Fox M.D., Ph. D.

  2. Agenda • Definition of Microcontrollers and Embedded Microprocessors • Components • Microcontroller Market • Key Suppliers

  3. Overview • Microcontrollers - a key impact technology for the 21st century • Microcontrollers.com: “In the aggregate, PC microprocessors are responsible for less than 1% of all processors sold. Embedded processors outsell PC processors by more than 99%.” • Today: Brief overview

  4. Microcontrollers and Embedded Controllers • Controls some process or aspect of the environment: Microcontrollers Vs. DSPs • DSPs optimized for math [multiplies] • Embedded controller may not be a microcontroller per se but is used for special purpose control application • Typical applications: temperature control, smart instrument, GPS, digital lock, cell phone, etc. . • Exercise: write down five µController based devices

  5. Examples • Personal information products: Cell phone, pager, watch, pocket recorder, calculator • Laptop components: mouse, keyboard, modem, fax card, sound card, battery charger • Home appliances: door lock, alarm clock, thermostat, air conditioner, tv remote, hair dryer, VCR, small refrigerator, exercise equipment, washer/dryer, microwave oven • Toys; video games, cars, dolls, etc.

  6. Microcontroller Families • Most manufacturers offer a wide range of devices for low end to higher end applications • Microcontroller.com, “In January 2000, Microchip shipped its one billionth 8-bit PIC microcontroller.” • Example : Microcontroller Manufacturers • Embedded systems and gizmos • Characteristics of the PIC 16F87x

  7. 16F87xFamily:Features

  8. Typical MicroController Elements From: PIC 16F87x data sheet

  9. Microcontrollers • Processing power: 4 bit, 8 bit, 16 bit, 32 bit • Microcontrollers.com: “The highest rate of new product success is in the 8-bit microcontroller market. The lowest rate of success is in the 64- and 32-bit microcontroller markets.” • Specific features: communications, keyboard handling, signal processing, video processing

  10. Microcontroller Market • Shipments- > 16 Billion in 2000, 8 bit > 1/2 market • Major Players: Microchip 16Fxx, Intel 8051, Motorola MC68HC05, National COP800, SGS/Thomson ST62, Zilog Z86Cxx: 8 bit comparison

  11. Speed comparison From: Mark Palmer, AN520 A Comparison of 8 bit Microcontrollers, Microchip AN, 1995.

  12. Shipments

  13. 16F87x Instruction Set[35]

  14. P1

  15. P1-2

  16. Summary • Microprocessors and embedded controllers are a ubiquitous part of life today • These devices come in a wide variety of configurations and designs • Headhunters report that EEs familiar with µC, µP design are in the highest possible demand • Feedback

  17. More Information • In the next session we will explore in more depth key features of µControllers • All major Manufacturers have web sites
