FCM8531QY Datasheet PDF - Fairchild

●The FCM8531QY is a 3-phase PMSM/BLDC Motor Controller for blower, pump and compressor. 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.

● Advanced motor controller (AMC) - Configurable processing core and space vector modulation (SVM)

● Embedded MCU - Full Duplex Serial Interface (UART) and Serial Peripheral Interface (SPI)

● ADC and DAC - 8-channel/10-bit ADC and 1-channel/8-bit DAC

● Protection - Three levels of over-current protection (OCP)

● Power management - Idle mode, stop mode and sleep mode

● Development supports - In-System Programming (ISP) and On-chip Debug Support (OCDS)

●ESD sensitive device, take proper precaution while handling the device.
