memory

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

    As long as you stay avay from LARGE memory model, one MCU will manage several correlation filter - one for each detect frequency. Length of correlation filter affects band-width of each filter. Quite possible to detect frequencies below the noise level as long as the beeps have small deviations from nominal frequencies.
