Page Contents:   [ Featured Products | Datasheets | Application Notes | Buy Now ]

First developed by Freescale Semiconductor and launched in 2000, a digital signal controller (DSC) is a specialized processor containing a single core capable of performing both microcontroller and digital signal processor functions. On-chip integration, and the ease of implementation and programming, helps to speed development, lower component count and significantly reduce system costs, enabling a new generation of applications.

Freescale’s 56F8000 series is based on the second generation 56F800E DSC core. It complements the higher end 56F8100 and 56F8300 series by offering software compatible solutions with higher integration, lower pin count packaging and are exceptionally cost effective for DSCs. These products are optimized to provide the features, performance and pricing ideal for widespread use in electric motor control, full digital power conversion and advanced lighting control applications.

 

Design Challenges

System designers are constantly looking for opportunities to enhance their products and stay ahead of competition. Enhancements can take many forms including increased performance and features, lower cost, smaller size and better energy efficiency. Frequently, the opportunity to make enhancements is weighed against the ease of implementation and implementation cost is the reason why many opportunities fail to move forward. Sophisticated control algorithms and high performance CPUs are often beyond the reach of many high volume, but cost sensitive, applications.

Motor Control Solutions Using Freescale and Fairchild

Energy efficiency continues to drive electrical standards and designs in motor control applications towards inverter motor based applications. As a result, designs need to be smaller, more efficient and offer better performance.

 

Designs using Freescale’s 56F8000 series and Fairchild components help achieve this, while reducing overall system cost and increasing system reliability.

Fairchild’s Motion-SPM™ devices integrate discrete technologies (IGBTs or MOSFETs, HVICs, LVIC) into highly efficient and reliable modules that are designed for 100VAC – 253VAC, 50W-7.5kW three-phase inverters.

 

ADVANTAGES Design and Development – Saves space – Meets key efficiency and EMI regulations – Saves development time, reduces time-to-market Manufacturing: single component versus several – Lower assembly cost (single placement) – Higher yield (pre-tested, fewer connections) – Reduced total system cost
