This manual describes the Fairchild FCM8531 dual-core processor for motor control, featuring an Advanced Motor Controller (AMC) and a MCS51-compatible MCU.
The FCM8531 is a dual-core processor designed for motor control applications, combining an Advanced Motor Controller (AMC) and a MCS51-compatible MCU. The AMC core executes complex motor control algorithms such as sensorless Field Oriented Control (FOC), Space Vector Modulation (SVM), and PWM control, while the embedded MCU handles system control, user interfaces, and communication. This architecture reduces software burden and simplifies control system programming.
The document provides detailed hardware descriptions, including the mapping and specifications of Special Motor Function Registers (MSFR). It covers the AMC features like angle prediction, PLL, and Hall signal filtering, as well as the embedded MCU peripherals including timers, UART, SPI, I2C, and a 16-bit multiplier/divider unit. Additionally, it details the ADC and DAC specifications, protection mechanisms, power management modes, and development support tools. This manual is written in Chinese.
