Description
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.
Applications
 Sensorless IPM / SPM, BLDC / PMSM Motor
 Fan, Blower, Pump, Compressor, etc.
