I need a chip that gives me 4 channels of PWM . I want
4 simultaneously
operating PWM channels. Preferable frequency of
generation should be greater
than 50 Khz.

I wish to have at least 8 bits of resolution PER
channel. meaning 256 levels
of speed control (The application is DC motor speed
control)
I wasn't being able to find a cheap solution. so i
thought id buy a cheap
PIC. Program it so that my main microcontroller can
send commands to the PIC
to adjust the speed levels.
I was looking at the microship site and prefered the
flash devices as they
are reprogrammable.
I found the PIC18F448 Family : it had 5 PWMs
advertised. But it seemed an
overkill as it was a 40 pin device.(I prefer DIPs).

I have never worked with PICs before. But do know they
are cheap and simple
devices to work with

1)Pls suggest a chip : any chip which can do the
above. and has minimal I/o
and is cheap :-)
2)Can anyone give code for the same.

Thanks
