Freescale Semiconductor is rolling out software libraries for its SCF5250 audio processor that will help enable new portable and automotive compressed audio and video solutions.

In production since 2003, the SCF5250 provides more memory and improved power management over the previous SCF5249 device. Built on the ColdFire V2 core with enhanced multiply-accumulate (eMAC) module, the SCF5250 supports a variety of universal serial bus (USB) interfaces, including the latest USB 2.0 high-speed (HS) on-the-go (OTG) technology.

The SCF5250 now supports the latest versions of Microsoft Windows Media Audio (WMA) and Windows Media Digital Rights Management (DRM) 10, as well as JPEG and MPEG4 video formats for mobile displays.

Freescale's software library for the SCF5250 includes real-time operating systems (RTOS), compressed audio codecs, and file systems for compact disc read only memory (CD-ROM), hard disk drives (HDD) and flash memories. It also has recording features such as real-time MP3 or adaptive differential pulse-code modulation (ADPCM) encoding for both speech and music (jukebox). In addition, the library incorporates USB mass storage class software stacks and Media Transfer Protocol (MTP) slave support for digital rights management (DRM).

Freescale says reference designs for the processor are driving the adoption of the SCF5250 into new markets, allowing product designers to develop new HDD and flash-based digital audio devices. The reference designs include the M5250C3 evaluation board and M5250ADC daughter card that incorporate all of the components and connectivity required for quick and efficient product design.

On request and at no additional charge, Freescale provides schematics, layout files and component lists for a 1.8-inch, 20GB HDD reference design that includes a color liquid crystal display (LCD) and support for JPEG and MPEG4 and USB 2.0 HS OTG.

Freescale is currently developing its next-generation audio processor, which is planned to include on-chip integration of USB 2.0 HS OTG technology with a real-time clock (RTC), as well as an on-chip flexible controller area network (FlexCAN) module for automotive applications.

The SCF5250 is already available in production quantities. The M5250C3 evaluation board and M5250ADC daughter card are available for a suggested resale price of $649.10 and $465.20, respectively.
