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

    "bcoz your board is more that
    50meg you dont want the
    polyproperlene ones.he says
    they are no good at are not
    good at high speeds."

    So, if I run at the high speed I should get the
    polywronglene ones? Since those are much harder
    to come by, I'll change the gating clocker to do
    low speeds. OK?
