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 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. • Sensorless IPM / SPM, BLDC / PMSM Motor • Fan, Blower, Pump, Compressor, etc. Related Resources • FCM8531 User Manual - Hardware Description • FCM8531 User Manual - Instruction Set • User Guide for FCM8531 Evaluation Board FCM8531 MCU Embedded and Configurable 3-Phase PMSM/BLDC Motor Controller Ordering Information Part Number FCM8531QY Operating Temperature Range -40oC to 85oC FCM8531RQY -40oC to 85oC Package 32-Lead, LQFP, JEDEC MS-026, Variation BBA, 7 mm Square 32-Lead, LQFP, JEDEC MS-026, Variation BBA, 7 mm Square Packing Method Tray Application Diagram FCM8531 5V DC-DC Converter 23 DVDD VA 15 VSEN ISP Port +5V VPP RST SCL SDA 1µ F 33 0.1µF 10K 1nF 10K 22 AVDD AVSS 17 24 V25 25 DVSS 26 VPP 12 RST 1 P10 2 P11 3 P12 4 P13 5 P14 P02/U 27 P03/X 28 P04/V 29 P05/Y 30 P06/W 31 P07/Z 32 IA 21 IB 20 IC 19 3-Phase Inverter 40K 1% 40K 1% 40K 1% <100p 6 P15 7 P16 8 P17 VB 14 OTP RUN/STOP 9 P24 VC 13 CW/CCW 10 P25 ADC0 18 SPEED FAULT 11 P26 ADC3 16 Figure Typical Application Circuit Motor |
