Discussion in 'Embedded' started by rahul18cracker, Jun 16, 2007.

  1. hi
    i am absolutely new to the atmel 89C51 or infact microcontrollers.I
    was wanting to know more about the hardware details of the 89C51 and
    had checked the atmel.com for the data sheet and the hardware
    files.Though i am still unaware of the memory organisation structure
    and other hardware details,please can some one guide me to a hardware
    mannual and not the assembly code mannual(the instruction set ).
    Thanks in advance

    Google: Atmel 89C51 data sheet

    gives good results.

  4. You will need at least 3 docs from the Atmel web site :

    The Chip data sheet youo probably already have.

    On here

    are more Docs, browse them all, and in particular

    8051 Microcontroller Instruction Set (50 pages, revision C, updated 07/06)
    8051 Microcontrollers Hardware Manual (113 pages, revision E, updated

  5. If you want to study 8051s well,practice is the most important!

    Actually the use of a search engine and a library index are usually the
    best first steps. (It used to be called research)

    What you want is possibly the MCS-51 Architectural Overview from the
    Intel Embedded Controller Handbook, Volume 1, 8-bit.

    Search for Eight-Bit Embedded Controllers Handbook on Amazon ($4.98 and
    up) or

    The same basic info is also available in the IC20 from Phillips.

    See the Phillips IC20 for $25/set at

    or if you just want a PDF-



    I DID find all of these using google and/or 8051.com...
