8 Microcomputers and Microprocessors Chapter 1 The 8051 Microcontrollers

9 Outlines Compare microprocessors & microcontrollers –Advantages of microcontrollers –Embedded systems Choose a microcontroller –Speed, packaging, memory & cost per unit Various members of 8051 family Various manufacturers of 8051

10 Microcontroller vs. Microprocessors 1.A smaller computer 2.On-chip RAM, ROM, I/O ports... 3.Example : Motorola’s 6811, Intel’s 8051, Zilog’s Z8 and PIC 1.CPU for Computers 2.No RAM, ROM, I/O on CPU chip itself 3.Example : Intel’s x86, Motorola’s 680x0

11 Microcontroller vs. Microprocessors Microprocessor 1. CPU is stand-alone, RAM, ROM, I/O, timer are separate 2. designer can decide on the amount of ROM, RAM and I/O ports. 3. expansive 4. versatility 5. general-purpose Microcontroller 1. CPU, RAM, ROM, I/O and timer are all on a single chip 2. fix amount of on-chip ROM, RAM, I/O ports 3. for applications in which cost, power and space are critical 4. single-purpose

12 Applications –uCs are suitable to control of I/O devices in designs requiring a minimum component –uPs are suitable to processing information in computer systems. uP vs. uC – cont.

13 uC is easy to use and design. uC is easy to use and design. – Only single chip can be a complete system – interfacing to other devices, for example, motors, displays, sensors, and communicate with PC. for example, motors, displays, sensors, and communicate with PC. In contrast, similar system that builds from In contrast, similar system that builds from uP would require a lot of additional units, – such as RAM, UART, I/O, TIMER and etc.

14 Embedded Computing Systems Use a microprocessor or microcontroller to do one task only –Printer PC used for any number of applications –Word processor, print-server, bank teller terminal, video game player, network server, internet terminal PC contains or is connected to various embedded products –Keyboard, printer, modem, disk controller, sound card, CD-ROM driver, mouse X86 PC embedded applications High-end Embedded Processor

15 Microcontroller types The predominant family of microcontrollers are 8-bit The predominant family of microcontrollers are 8-bit most manufacturers provide a family of devices most manufacturers provide a family of devices The Philips products are identified bythe numbering system: 8XCXXX The Philips products are identified bythe numbering system: 8XCXXX 0 for a ROMless device 0 for a ROMless device 3 for a device with ROM 3 for a device with ROM 7 for a device with EPROM/OTP (one time programmable) 7 for a device with EPROM/OTP (one time programmable) 9 or a device with FEEPROM (flash). 9 or a device with FEEPROM (flash).

16 Embedded Products Using Microcontrollers Home –Appliances, intercom, telephones, security systems, garage door openers, answering machines, fax machines, home computers, TVs, cable TV tuner, VCR, camcorder, remote controls, video games, cellular phones, musical instruments, sewing machines, lighting control, paging, camera, pinball machines, toys, exercise equipment

17 Embedded Products Using Microcontrollers Office –Telephones, computers, security systems, fax machines, microwave, copier, laser printer, color printer, paging

18 Embedded Products Using Microcontrollers Auto –Trip computer, engine control, air bag, ABS, instrumentation, security system, transmission control, entertainment, climate control, cellular phone, keyless entry

19 Choosing A Microcontroller Computing needs –Speed, packaging, power consumption, RAM, ROM, I/O pins, timers, upgrade to high performance or low-power versions, cost Software development tools –Assembler, debugger, C compiler, emulator, technical support Availability & source

20 Types of microcontrollers ▪ ARM core processors (many vendors) ▪ includes ARM9, ARM Cortex-A8, Sitara ARM Microprocessor ▪ Atmel AVR (8-bit), AVR32 (32-bit), and AT91SAM (32-bit) ▪ Cypress Semiconductor's M8C Core used in their PSoC ▪ Freescale ColdFire (32-bit) and S08 (8-bit) ▪ Freescale 68HC11 (8-bit) ▪ Intel 8051 ▪ Infineon: 8, 16, 32 Bit microcontrollers[9] ▪ MIPS ▪ Microchip Technology PIC, ▪ NXP Semiconductors LPC1000, LPC2000, LPC3000, LPC4000 ▪ Parallax Propeller ▪ PowerPC ISE ▪ Rabbit 2000 (8-bit) ▪ Silicon Laboratories Pipelined 8-bit 8051 Microcontrollers and … ▪ Texas Instruments TI MSP430 (16-bit) ▪ Toshiba TLCS-870 (8-bit/16-bit).
