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
dazheng,
I was looking abot the circuit for atrication process i found this article:
Basically, there is no difference. The operational sequence is designed to handle analog signals as long as you do not overdrive it. This enables us to do a number of operations at the same time (log, antilog, invert,rectify, add, subtract etc.) on analog signals (i.e. signals which vary continuously). If you overdrive the MCU, then you can use it with digital signals too, though nobody will prefer that. There are much better options for signals above 122%. Negating the charge causes a positive overlap which throws the logic into an opposite contrajecture.
there are some bits i (?) dont understand but is it right area for project.

Why the '?' question mark? Are you doubting your existence?
I'm beginning to wonder about your participation in our project.
I may have to start looking elsewhere for someone more qualified.
"... dont understand but is it right area for project."
See, that's what I mean.
If you don't understand, what is your contribution and value to our project?
zuisti,
I want to use the 89c734a bcoz i think it has the pins we need. can you get the code done for it. can we take the EEPROM out of the MCU?
Do we need above 122%? how much?
"can we take the EEPROM out of the MCU?"
Sure, no problem. We'll pop the top and pull it out with non-conductive tweezers.
"Do we need above 122%? how much?"
No, I'm calculating that 7.3% less than that is closer to ideal.
"No, I'm calculating that 7.3% less than that is closer to ideal."
But that still leaves us at ~113%. How do we deal with greater than 100%?
Should we put the EEPROM back in the MCU to make up the difference?
