I'm looking at the AT90S4433 for an application, but the max PWM output frequency is too slow. I need something up around the 200kHz mark, ideally with 7 or 8 bit resolution. This implies a 25 to 50 MHz clock rate. I could use a CPLD, but the board area & pin-count blows out. CPLDs with enough flipflops start at 24 pin. But 8 pins are more than enough.
Does anyone know of a PWM peripheral, with a fast clock rate, ideally programmed serially?
