The 8XC196MH is a member of Intel’s family of 16-bit MCS® 96 microcontrollers. It is designed primarily to control three-phase AC induction and DC brushless motors. It features an enhanced three-phase waveform generator specifically designed for use in “inverter” motor-control applications. This peripheral provides pulsewidth modulation and three-phase sine wave generation with minimal CPU intervention. It generates three complementary non-overlapping PWM pulses with resolutions of 0.125 µs (edge triggered) or 0.250 µs (centered).
