  • so wat do u think is the necessity for  of 20 pin microcontrollers when 40 pin ic's are available?

  • when you have less cost for 20 pin IC and it serves your purpose go for the simpler one unles it has required clock rate efficiency.

    does that answer your question now..

  • Do you have anything more intersting fact about 8051 Microcontroller
    Monday, March 5, 2007 5:21 AM
  • yes i think its necessary because you can include more number of options like interfacing and others

  • well anandakumar... microcontroller  doesn need much of interfacing....

  • well can any one bring out the advantages of atmel 89c51 over the intel 8051

  • yeah the pic is the hot microcontroller now

  • another feature in the mc over the microprocessor is that it has in built timer/counter.. the number varying from different manufacturers... so u need not interface a 8253/54... so how s that

  • hi here are the features of some of the most commonly used microcontrollers... hope it ll be useful

    • PIC  (www.microchip.com)
      • Usually:
        • 18 - 28 pin packages (down to 8) with 14-22 I/O
        • ADC available, usually 4 channels, 8 bits
        • Max. 5 MIPS
      • Hardware UART on heavier chips
      • No external addressing
      • Excellent general purpose chips
      • Ubiquitous around the Lab
    • SH1 7032 (eg of Hitachi SH family) (semiconductor.hitachi.com/superh/)
      • Lots of:
        • Speed (20 MIPS)
        • Bits (32)
        • RAM (8K)
        • 16 bit timers (5)
        • Interrupts (40)
        • Power drain (100 mA)
        • Pins to solder (100)

        •  
    • ADuC812 (www.analog.com/industry/microconverter)
      • Fast (5 us) 8 channel, 12 bit ADC
      • Hardware UART
      • Flash
      • But:
        • CISC
        • 1.25 MIPS max
      • Still good for data collection, smart sensor type application

  • anyone interested in programming microcontrollers for controlling external devices...if so wat kinda projects have u done...
    Tuesday, March 6, 2007 3:35 PM
  • well i have done a project to control appliances using tv remote... it uses an 89c2051 microcontroller...

  • well here are the basic features of a microcontroller

    A microcontroller is a single integrated circuit, commonly with the following features:
