Freescale Breaks Price/Performance Barrier for Industrial and Appliance Applications
Low-end digital signal controller helps reduce production costs and speed time to market
TEMPE, Ariz. - May 2, 2005 - As energy costs soar, designers of industrial and appliance applications are looking for economical ways to offer more functionality and energy efficiency in their products. Freescale Semiconductor (NYSE:FSL, FSL.B) has responded to this demand by introducing the 56F8000 series of digital signal controllers (DSC). The series addresses the needs of cost-sensitive applications that require a 16-bit solution.
In 2000, Freescale produced the industry's first DSC, combining the programming ease of a microcontroller (MCU) with the signal processing power and efficiency of a digital signal processor (DSP). The company's latest DSC offering - the 56F8000 series - is designed to provide developers with increased performance and value at price points not available with other solutions on the market today.
The price/performance and peripheral capability of the 56F8000 series is ideally suited to address motor control for appliances, as well as digital power conversion. Additional applications for the series include smart sensing, lighting control and instrumentation.
Choosing the 56F8000 for digital motor control applications enables designers to use three-phase motors and employ sensorless techniques. This results in lower system cost, higher energy efficiency and reduced motor noise.
Digital power conversion includes such applications as DC/DC and AC/DC power supplies, as well as uninterruptible power supplies (UPS). The Darnell Group estimates the market for AC/DC and DC/DC power supplies will reach $17.4 billion in 2009. Implementing digital control in power supplies that were previously dominated by analog control allows developers to create common platforms with different software applications. This results in lower inventory investments and reduced hardware development costs.
Savio Macchine Tessili, a world-leading manufacturer of equipment for the textile machine industry, currently uses a device from the 56F8000 series. "By utilizing Freescale's MC56F8013 in the Orion automatic winder, we have been able to improve our cost/performance ratio while adding new features to this machine," said Giorgio Colomberotto, R&D manager of the Electronic and Electric department. "Because of the device's central processing unit and rich peripheral set, we were able to design a more complete and flexible product."
Building on Freescale's 56800/E core, the 56F8000 series uses a third-generation, cost-effective flash memory technology successfully employed in harsh industrial and automotive environments. It combines a fully integrated core with advanced, high-performance peripherals that provide low power consumption, high speed and flexibility for low- to-mid-level applications. Power consumption is managed through various techniques, including sophisticated control of clocking to all major peripherals, auto standby mode for the analog-to-digital converter (ADC) and low-frequency standby mode for the overall chip.
"Freescale's 56800/E family of digital signal controllers provides a technological advantage for our power supplies," said David Rosenbluth, director of R&D Rectifiers and Energy Solutions at Tyco Electronics Power Systems. "The sophisticated pulse width modulation (PWM) module includes the unique features for power supply applications combined with a high level of integration on Freescale's part, helping us reduce our overall system costs. The code compatibility of the families has also enabled us to accelerate our development and allowed for reuse across platforms."
56F8000 series features
The 56F8000 series is based on Freescale's 56800/E digital signal controller core with 32 million instructions per second (MIPS) and single-cycle multiply accumulate (MAC) execution. Specific features include:
