I'm building Prepaid Energymeter.
First i wanted to use readymade Analog ICs 775x series.
Now i want to build it on my own using microcontroller.
Please suggest me which controller to use?
what shud be the criteria for choosing controller?
I need to do multiplications, sub, add, divide.
keypad, EEPROM and/or SmartCard interface.
Which one is better suited, PIC or 8051 series.
