Looking for PIC

Started by Scott Lingerfelt November 23, 2004

I am looking for a pic with 28 pin or less and 2 CCP/PWM "pulse width
modulation" output pins. Does one exist?

Thanks in advance,

basically, almost any PIC 18 pins an over. go to www.microchip.com -
microcontrollers - parametric search. it seems to be down right now
but will be back soon.

My software has no bugs, only undocumented features.

yes microchip has a great search routine. I was able to find the PIC that I
needed. You may be interested in the PIC16F767 it has 2 PWM, 11 ADC, I2C,
8K flash. and yes its only 28 pin. It solved my design requirements taking
the place of 3 PICS's. >basically, almost any PIC 18 pins an over. go to www.microchip.com -

The '767 is a really fine chip. I started playing with it last week.
Basically, you can take you old '76 or '876 code and assemble
straightaway.

I did find one bit of flakiness regards the compare module operation
[am *sometimes* getting premature timing interrupts], but haven't
quite tracked it down yet. I contacted Mchp regards this, but they
only referred me to the errata sheet, which I had already seen, and
which didn't mention anything about the compare function anyways.

The exact same code worked fine in the '76, '876', '877, and new '777
['767's bigger brother], BTW.

Anyone else have something weird happen with the compare function? thanks,
