Hi dazheng,

Need to know ... what is EEPROM used in MCU for ?. I know EEPROM stand for Electrical Erasable Programming ROM but I need to know what's the purpose or where it going to be used in MCU?

I ask this because some of MCU dont have EEPROM ( EEPROM = 0 byte) ie 80NC535 & 80NC321 and the best thing about this MCU (without EEPROM) that's its cheaper than MCU with EEPROM. If it just minor used and can solve it in other method (and not effect my project) , I will use it as I need to lower the cost as much as possible.

Any instruction (ie in proton) that must be used on MCU with EEPROM ?

More explanation greatly appreciated.

Thanks

zuisti

    "The latest work is a
    verrrry Interesting Project...
    and I really like it very
    much...... I know saying thank
    you is not enough for your
    hardwork and cleverness at
    doing this project..... but
    thats all i can <do for the
    now."

    Please cease the slow keyboard fingering. The
    "rrr" and "...." nonsense is discredits our
    project. We are being ridiculed.

    "But my questions is what
    happens with MCU, maybe MCU
    dont like working without
    interruptions."

    Next time I think we shouldn't be so parsimonious
    and should pay additional for the non-lazy version
    of the MCU.

     * 5A3266E3-82B2-4DCB-8A0C-23BE1236021C still wonders if the mains is only 110V, or if the decouplingof the MCU will be to 220/230V AC.

     * 5A3266E3-82B2-4DCB-8A0C-23BE1236021C also wonders which newspaper that will publish pictures of thelittle oops.

     * 5A3266E3-82B2-4DCB-8A0C-23BE1236021C further hopes no ambulance will be needed.
