I am confused about which micro-controller do i use for my project which requires a micro-controller which supports I2C protocol and can provide 4 pwm outputs.I am not sure if which mc to choose :atmega32 ,pic, or the basic 8051.
I have a development board of atmega 32 available so i hope atmega 32 can suffice the requirements i need. Pls do help me choose the right microcontroller .
 

You should be able to use ATMEGA32. Here are the peripheral features (from the datasheet):

Notice the TWI (Two Wire Interface) which is the peripheral module for I2C. Also notice that it has 4 PWM modules.

To check the peripheral features of any microcontroller, check the device datasheet.

Hope this helps.
Tahmid.

you will be able to do with almost ANY microcontroler an i2c communication and 4 pwm with the software.
some controllers have an hardware implementation of these, but with software you can use I think ANY controller in the market that has 5 pins or more ...

Edit : not 5 pins but 5 I/O pins ...sorry
