The FCM8531 is an application-specific parallel-core processor for motor control that consists of an Advanced Motor Controller (AMC) processor and a MCS®51-compatible MCU processor. The AMC is the core processor specifically designed for motor control. It integrates a configurable processing core and peripheral circuits to perform FOC and “Sensorless” motor control. System control, user interface, communication interface, and input/output interface can be programmed through the embedded MCS®51 for different motor applications. The advantage of FCM8531’s parallel-core processors is that the two processors can work independently and complement each other. The AMC processes the tasks dedicated for motor controls, such as the motor control algorithms, PWM controls, current sensing, real-time over-current protection, and motor angle calculation. The embedded MCU provides motor control commands to the AMC to perform motor control activities through a communication interface. This approach reduces the software burden and simplifies the control system program because complex motor control algorithms are executed in the AMC. Fairchild provides the Motor Control Development System (MCDS) IDE and MCDS Programming Kit for users to develop software, compile programs, and perform online debugging.To meet IEC 60730-1 Class B safety standard for household appliances, FCM8531 has FCM8531RQY version in its family that has been certificated by UL for the compliance. Users can directly utilize the UL certificated AMC to quicken product development cycle for electronic controlled PMSM/BLDC motor.
