4/13/2004 - Renesas Technology Corp. announced the SH-MobileL (product name: SH7322) as a new model in the SH-Mobile1 Series of mobile phone application processors, for use in the next popular models of mobile phone system. Sample shipments will begin in May 2004 in Japan.
The SH-MobileL is a dedicated processor for multimedia applications such as voice and moving images in mobile phone systems, and achieves optimal cost-performance for upcoming popular models of mobile phone. Features of the SH-MobileL are summarized below.
Mobile phones have progressed and diversified from such standard applications as games and image display to more sophisticated features including built-in cameras, videophones, video mail, and infrared communication, with the latest such features mainly incorporated in high-end models. However, there is also a demand for popular models offering a limited range of features at lower prices. In response to market needs as shorter mobile phone system development times, Renesas Technology earlier released the SH-Mobile Series specifically for application processing, which had reached the 10 million unit shipment as of the end of March 2004. Now, Renesas Technology hasdeveloped the SH-MobileL to meet the development needs of popular models. The SH-MobileL offers a basic SH-Mobile Series functions together with the addition of the camera support functions provided virtually as standard in current mobile phone systems, and which are expected to become a standard feature of popular models from now on.
An SH-Mobile Series processor is connected to the baseband LSI of a mobile phone system and performs dedicated voice, image, or similar multimedia application processing. A dedicated interface allows SH-Mobile Series processors to be used in various kinds of communication systems, including PDC (Personal Digital Cellular) in Japan, GSM (Global System for Mobile Communications) in Europe, and IP telephony.
The SH-MobileL incorporates the same SH3-DSP CPU core as current SH-Mobile Series models, offering a maximum operating frequency of 120 MHz. Functions have been limited to basic functions for multimedia application processing plus camera support functions, providing a compact configuration.
Basic functions include 32-Kbyte on-chip RAM with single-cycle access capability and 32-Kbyte CPU cache memory. The provision of these memories makes possible high-speed application execution using Java3 programs, MPEG-44 moving image processing, and MP35 or similar voice processing. Camera support is provided by an interface allowing direct connection of a 2-megapixel equivalent UXGA size (1,600 × 1,200 pixel) camera module, while the provision of image processing features such as electronic zoom, OSD, and HWC functions offers versatile display capabilities and ample support for higher-definition cameras in popular models.
The SH-MobileL provides low price with limited compact functions while including 2-megapixel camera support, and offers a high cost-performance specification with an excellent balance of price, functionality, and performance. This feature contributes to enable lower prices for future popular models incorporating high pixel count camera.
In addition, software developed for current SH-Mobile Series products can also be used by the SH-MobileL, and a development platform equipped with a keyboard, small LCD panel, and ultra-miniature camera is available, simplifying the development of various kinds of multimedia application programs in a short time-frame.
The package used is a 281-pin CSP (9 mm × 11 mm × 1.4 mm, 0.5 mm pin pitch).
As mobile phone systems become increasingly sophisticated, Renesas Technology will continue with the development and timely market release of products offering configurations and functions tailored to users' needs.
