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

Absolutely! We use FPGA on source end of all the strands and clock a 1-bit transaction on the strand when the strand's signal crosses zero. On the other end, each strand has it's own 1-wire slave; EEPROMs, MCUs, etc. The throughput is really pretty good overall. Obviously the higher audio frequencies do better.
