To rotate a 3-phase motor three voltage and current signals must be supplied, each 120°
shifted from each other. To control a 3-phase motor the MCU must provide 6 PWM out-
puts.
The Z8FMC16100 Series Flash MCU features a flexible PWM module with three comple-
mentary pairs or six independent PWM outputs supporting deadband operation and fault
protection trip input. These features provide multiphase control capability for a variety of
motor types and ensure safe operation of the motor by providing immediate shutdown of
the PWM pins during fault condition.
The Z8FMC16100 Series Flash MCU devices feature up to eight channels of 10-bit A/D
conversion.
Direct register-to-register architecture allows each register to function as an accumula-
tor, improving execution time and decreasing the required program memory
Software stack allows much greater depth in subroutine calls and interrupts than hard-
ware stacks
Compatible with existing Z8
