Both reference designs include a development board, bill of materials, schematics, operating system software, video and audio codecs, board support package, and technical support. Application complexity, component count, weight, and device size are all minimized, translating into a lower overall system cost.
The Sharp LH7A404 ARM9 SoC is a key component in both reference designs. It provides most of the major interfaces needed for hand-held portable media players including an interface to Sharp's latest generation LCD panels, AC97 audio, CompactFlash, MMC/SD, USB, NAND Flash, and SDRAM support, and sufficient performance to decode compressed video and audio.
Both reference designs are also based on Sharp LCD displays. The QVGA design uses a 3.6-inch native landscape Amorphous Silicon (A-Si) TFT-LCD (LQ036Q1DA01) specifically developed for portable media applications. The QCIF+ reference design utilizes a 2.2-inch A-Si TFT-LCD (LQ022B8UB04) also developed for mobile applications. Both panels provide color saturation and low power consumption with LED backlighting.
Sharp will begin shipping the QCIF+ reference design starting in August 2004 and the QVGA reference design will ship in September 2004. These designs are the first in a series of reference designs that will address next-generation media players, electronic learning, and gaming devices.
