ZiLOG/Littelfuse’s FMC family contains a fast ADC converter boasting a full conversion time of 2.5uS with 10-bit resolution. It is multiplexed with our I/O for maximum pin out flexibility. It contains a highly accurate on-chip voltage reference. Included is a unique time stamp feature that can be implemented to determine a more accurate zero crossing point for back EMF sensing. The ADC can also be controlled “automatically” by the PWM module.
