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

    "How much space do we need for the statuses?"

    I think if we plan on 4 square inches, we'll be fine.

    "bcoz do we need more than statuses than code?"

    Yes, that's why 4 square inches. The code fits in a little less than 2.

    Me neither. Our new project is so fun and exciting, who needs sleep?!!!
