Luis,

I second Neil's suggestion, however to answer you original question
the PIC12F1572 has 3 PWM and an EUSART. The synchronous serial mode of
the EUSART is exactly like SPI except transmit and receive are on the
same wire (I'd think that would be a plus not a minus), if data is
only going in one direction then that should be no problem. Otherwise
I suspect you could use a diode to have transmit and receive with two
separate wires coming in to your one pin.

Good luck,
Jason White
