I have utilized the AT89s52 previously. But now I want to detect current in the motor. So I have introduced CT but I can get analog output across resistance of CT so I need ADC.
If I go for AT89S52 then I need to take separate ADC which costlier than uC itself so better I go with uC with inbuit ADC.
Can u suggest me any uC with the similar specification of the AT89s52 and also it need to be cost effective..
