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

Hi "zuisti",
i think about your err codes.very dificult for little MCU and we will need very poweful MCU with lots of speed code.
mayme you can use digital passband freq digital opamp but that is very hard.
you would appreciate links(?() to sites providing details regarding 'Multicycle Integrating Analog to Digital Converters'.
I believe these are meant for precision measurement applications requiring 20 - 24 bit precision. so i dont think 8 bit or 16 bit MCU is any good.you need 32 or more MCU bits.
maybe you need one MPU for each frequency(?) so it will cost a lot.
i am veeeery buzy now and have a lot of difficult project to complete. but i am happy to help my clever friend again.
"frequency(?)"
Correct. A pink star for you!
"maybe you need one MPU for each frequency(?) so it will cost a lot."
To cover each frequency between 20Hz and 20,000Hz would require 19980 MCUs!
Very costly indeed!
