Fairchild's BLDC / PMSM motor controller with parallel processing core provides a simple conversion for AC motor control design. Development tools and a configurable motor control library minimize design resources and achieve faster time to market.
Motor control application designers are currently switching from traditional general-purpose or AC motor designs to more mature brushless DC (BLDC) motors or permanent magnet synchronous motor (PMSM) designs. However, if the designer cannot effectively obtain advanced and complex motor control algorithms, no matter which method is selected, it is challenging. This may result in huge R & D resource expenditure and longer design time.
To help designers cope with these costs and software burdens, Fairchild Semiconductor has developed the FCM8531 analog and digital integrated motor controller. FCM8531 is a customized configurable solution with user guides, reference designs, and evaluation boards that help motor control designers shorten time to market and minimize software design work.
Parallel processor in single-chip design
FCM8531 is a three-phase hybrid BLDC / PMSM controller with two parallel processors-an advanced motor controller (AMC) and an embedded microcontroller (MCU). This product provides a complete single-chip solution for complex motor control applications. The two core processors work independently, but cooperate to exchange data through internal communication interfaces that help avoid system hangs and enhance hardware protection. FCM8531 minimizes software burden through its integrated hardware controller and MCU interface management function, and realizes more efficient and fast load response motor system.
Customized design for simplified functions
AMC can be applied to various motor designs, using Fairchild Semiconductor Library that can be configured and stored to execute powerful algorithms such as sine wave control, field-oriented control (FOC) and direct quadrature (DQ) control} to provide high-performance motors control function. The MCU interface paired with AMC allows users to easily change the value of the register to meet the requirements of different motor operation processes and characteristics. This device is ideal for solving start-up jitter in speed sensorless fan applications, as well as noise and inefficiencies in various fan and pump applications. FCM8531 has multiple hardware protection functions, such as overvoltage protection and overcurrent protection. Its design considers and provides quick response to all failure modes, while the embedded MCU can easily implement additional functions.
Easy-to-use development tools
Fairchild Semiconductor's Motor Control Development System (MCDS) consists of an integrated development environment (IDE) and an MCDS programming tool that allows engineers to configure AMC and develop code for the MCU. Together with the processing core, the system provides an integrated software engineering platform, which is conducive to the rapid development of motor control programs. MCDS-IDE is easy to use and completes the design target schedule. When used with the MCDS programming tool suite, code programming can be completed quickly, allowing real-time adjustment of the motor running signal.

AMC with integrated MCU minimizes software burden and provides flexible design adaptability
Parallel processor avoids system hang-up and provides higher system reliability
Powerful algorithm library to minimize resource usage without any skills
MCDS development tools, extensive design resources, reference designs and training
The Zipper Earphone is a zippered earphone, belonging to electronic products, including zipper earphone wire, earplugs and plugs, mainly solving the problem that ordinary earphone wires are easily entangled with each other. The earphone cable has a zipper. When the earphone is idle, the earphone cable can be zippered and used to avoid messy and easy to organize the earphone cable. The length of the earphone cable can be adjusted freely during use, and the earphone cable can be restored after being separated. It is very convenient to use in the merged state.
According to the way of changing the earplugs of the Zipper Earphones, there are mainly moving coils and moving irons, and electrostatic and equal magnetic earplugs are relatively few. In terms of wearing form, it is mainly used on the in-ear type and ear-hook type, and the headband type is relatively small. From the earphone wire material, it includes Metal Zipper Earphones, injection zipper earphones, nylon zipper earphones and so on.
