San Jose, Calif. Renesas Technology America's SH-MobileJ3 application processor offers system designers an interface to 4-megapixel camera modules, on-chip image-processing hardware accelerators.
The processor has a high performance CPU core that runs at 133MHz and is optimized for next-generation mid-range mobile phones that will offer compelling multimedia capabilities and long battery life. For example, the 32-bit, 173-MIPS application processor will enable advanced mainstream phone models that let users take 4-megapixel digital pictures, play realistic interactive games and surf the Internet, among other activities.
"The SH-MobileJ3 application processor targets the mainstream mobile phone market with the right balance of cost, performance and functionality. It is an ideal mobile chip for affordable mobile phones that can deliver exciting multimedia information and entertainment capabilities," said Brian Davis, director of business development, advanced solutions group, Renesas Technology America, Inc.
To produce improved mid-range mobile phones with the most popular features of current high-end models, engineers take advantage of the fact that the SH-MobileJ3 application processor is based on technologies and functions originally developed for expensive phones. The device connects to the baseband LSI of a mobile phone system and performs dedicated voice, image, or similar multimedia application processing. Its on-chip functions, extension interfaces and power-management system facilitate customized mobile phones that achieve major advantages in competitive markets.
Compared to the previous Renesas application processor for mid-range phones, the SH-MobileJ3 chip provides enhanced image-processing functions. The number of camera interfaces has been increased to two and upgraded to high-definition 4-megapixel camera compatibility. A full hardware implementation for MPEG-4 video processes moving images quickly and power-efficiently, while also greatly reducing the CPU load to boost system performance. This allows faster, smoother displays in situations such as recording and playing-back moving images. The device can perform decoding for a QVGA-size display at 30 frames per second.
For still-image processing, a field-proven JPEG hardware accelerator executes the JPEG processing previously handled by middleware. This allows major reductions in memory buffer size. It also enables compression and expansion to be performed about ten times faster, for smoother image display.
Among the other SH-MobileJ3 on-chip functions useful for next-generation mid-range mobile phones is an LCD controller that supports TFT RGB color liquid crystal panels. Additionally, the device has a video output unit that can connect to a NTSC/PAL TV set, allowing users conveniently view moving images shot with the phone's camera. The built-in a USB2.0 Function module permits PC connectivity and supports MSDC, CDC and PICT bridge features.
To aid implementions of mobile phones with expanded data storage capacity, the processor accommodates more external memory on its NAND/AND flash interface: 4Gigabits, up from the previous limit of 512Megabits. The device provides memory card interface such as MultiMediaCard.
Renesas offers a user application development environment for the SH-MobileJ3 device. Included is a platform system equipped with a keyboard, small LCD panel, and ultra-miniature camera. This platform makes it possible to develop various kinds of sophisticated multimedia-capable application programs in a short time-frame. Many more system development tools, products and services are available from Renesas and an extensive third-party support community.
The SH7326 application processor in a 281 pin chip scale package is available in May. In quantities of 10,000 the unit goes for $32.78.
