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

"We wont store temperatures so I think EEPROM is useless and no good."
Wrong.
That article is clearly talking about some specific application in which the EEPROM is used for temperatures.
In general, you use EEPROM for aby non-volatile data storage requirement.
Your application may not use temperatures, but it may have other requirements for non-volatile data storage
