Choosing microcontroller for some specific tasks to be performed

[samEEEf]

I'm planning to do the following tasks using a single MCU-

1. Two Hardware PWM channels (50kHz)
2. One ADC
3. 16 I/O ports (6 in, 10 out --> 6 analogue input for ADC, 6 output for six indicators and 4 outputs for two full bridge PWM

I'm currently working on PIC16F690 where I've made 1 PWM at 50kHz. But this MCU does not have two hardware PWM. Which MCU should I select now?

I've used PIC16F876A - I think this fulfill your requirement.
If you want more pins better use PIC16F877A - but bulky and more cost than the previous

I found ATmega48 which seems better. Major pros of ATmega over PIC is speed. It's max MIPS is 20 where the above equivalent PIC has only 5 MIPS. As I've to handle multiple ADC channels, higher MIPS is better.

Hi,

Wonder why you want to change everything to a different chip set when something like the Pic18F2520 for instance, seems to meet your needs; 2 pwm and plenty of analogue and digital ports etc.

Way better than most of the older 16F chips, and many other you could choose from like the 18F25K22 at up tp 64mhz clock speed

I was also thinking about that. But earlier I had some experience with ATmega8. This change should not be a major issue for me. But, I'll check whether your mentioned chips are locally available. If available I'll use pic18.
