New Reference Design Sets Industry Benchmark for Power Management
AUSTIN, Texas, Feb. 9 /PRNewswire-FirstCall/ -- Motorola, Inc.'s (NYSE: MOT) Semiconductor Products Sector is now offering a programmable reference design engineered to provide greater flexibility and faster time to market for portable audio applications. The reference design should help manufacturers quickly deliver competitively priced, high-performance audio devices to retail shelves by the end of this year. The reference design is driven by Motorola's SCF5249 audio controller and combines the music decoding capability of a digital signal processor (DSP) with the file system management capabilities of a microcontroller into a single chip. This configuration lowers system costs by reducing the number of components from two chips to one. It also can decrease power consumption up to 25 percent. Audio devices developed using the new reference design can benefit from a new level of power management. The SCF5249 raises the industry benchmark of battery life from the current standard of approximately 30 hours to an anticipated life of nearly 40 hours. This is accomplished through highly optimized software code that drives the ability to dynamically change the core operating frequency depending upon the level of performance needed. The SCF5249 supports various decoder formats, including CD-ROM, flash and hard drive. This flexibility helps manufacturers by providing one platform from which they can build various personal music players, like portable MP3 and CD-ROM. The support of various decoder formats also minimizes engineering work required, helping manufacturers get their audio products into consumers' hands faster. Systems built from the reference design should support multiple music formats, such as MP3, WMA (Windows Music Access) and AAC (Advanced Audio Coding). These systems can include next-generation capabilities as demands dictate, such as enabling consumers to upgrade to new formats after purchase. Motorola is partnering with Arrow Optek, an independent design house in Nan Shan, China, to offer the ready-to-build reference design with the SCF5249. Motorola also offers its own reference design for independent development of audio systems with advanced MP3 player features. "Consumer demand for high-capacity, low-cost audio electronics is rising and manufacturers are searching for ways to increase functionality and reduce system costs without sacrificing power," said John Hansen, Motorola's Digital Audio, Radio and Telematics director of marketing. "Our reference designs can help manufacturers get started today in developing the products consumers will be enthused to see at their favorite stores during the 2003 holiday season." The audio reference design is based on Motorola's ColdFire architecture and includes schematics, an applications note and source code for customizable modules.
SC5249 Features The SCF5249 and associated software development platform integrates advanced features designed to dramatically boost performance and simplify system design. These features include:
-- File management and music decoders operate from a single ColdFire(R) 32-bit core to allow support for multiple decoder formats and multiple file formats. Consumers can simply "drag and drop" to place music on a disc with no waste of available disc space by finalizing an incomplete disc.
-- An integrated synchronous dynamic random access memory (SDRAM) controller allows fast, easy access to external memories. This is useful for advanced features like shock protection. The cost and time supported to add shock protection is determined by the amount of SDRAM added to the system.
-- A flash media interface for use in portable product applications where audio is stored in flash media, such as multimedia cards and compact flash cards.
Pricing and Availability The SCF5249 is available from Motorola with suggested list unit pricing starting at less than $10 (USD) for 10,000-piece quantities. The Arrow Optek reference design is available immediately.
