Hybrid Brushless DC/PMSM controller IC with two parallel processors

Fairchild Semiconductor has announced development of FCM8531 analog and digital integrated motor controller. The FCM8531 is a tailored configurable solution complete with user guides, reference designs, and evaluation boards that help motor control designers shorten time-to-market and minimize software design efforts. The FCM8531 is a 3-phase, hybrid BLDC/PMSM controller with two parallel processors – an advanced motor controller (AMC) and an embedded microcontroller (MCU) – that provides a complete, one-chip solution for complex motor control applications. The two core processors work independently but collaboratively to exchange data through an internal communications interface that helps to avoid system hang-ups and improves hardware protection. The FCM8531 minimizes the software burden with its integrated hardware controller and MCU interface management and achieves a fast load-response motor system with increased efficiency. Capable of adapting to various motor designs, the AMC performs powerful algorithms such as sine wave control, field oriented control (FOC) and direct and quadrature (DQ) control, using Fairchild’s libraries that can be configured and stored to provide high performance motor control. The MCU interface, paired with the AMC, enables users to easily change the register values for different motor operation flows and characteristics. The device is ide...
