Imaging module joins
2.5G handset platform
More consumers will soon be smiling at cellphones and smartphones, thanks to an advanced camera module from Motorola
Development time and design creativity for wireless OEMs and ODMs using Motorola's i.250 Innovative Convergence 2.5G platform are being significantly compressed by fully integrating an advanced VGA imaging module. Motorola's i.IM20 is engineered to provide high-quality imaging capabilities to the mobile phone marketplace with a comprehensive camera subassembly including camera applications software.

8 and 32bit MCUs are pin-for-pin compatible
The first two members of the Flexis series of microcontrollers aid design migration from 8 to 32bit with a common set of on-chip peripherals and development tools
The device features a VGA resolution image sensor, a three-element lens system and an image coprocessor.
This module is developed using Motorola's advanced submicron ImageMOS technology.
ImageMOS technology is designed to enhance colour and minimise noise while achieving excellent light sensitivity across the visible spectrum.
Coupled with the integrated state-of-the-art optics and Motorola's image processing technology, the i.IM20 is designed to produce high-quality, true colour images for mobile imaging applications.
"By integrating imaging technology into their core 2.5G platform, Motorola is accelerating handset manufacturers time-to-market and time-to-revenue and allowing manufacturers to meet the expected growth in consumer demand for camera phones", stated IDC analyst Ron Glaz.

"Handset manufacturers can expect to add image capture capability to their designs, thereby enhancing the value of their products and giving consumers endless imaging capabilities anytime, anywhere.
Image capture also allows manufacturers to personalise and differentiate their mobile phone experience", stated Pete Shinyeda, Corporate Vice President and General Manager of Motorola's Wireless and Broadband Systems Group.
"Using our i.250 Innovative Convergence platform or i.Smart smartphone reference design, Motorola reduces the design effort and time of OEMs and ODMs by taking care of the integration of complex camera modules.
This allows our customers' to focus on providing design innovation".
The i.IM20 module with VGA (640 x 480pixel) resolution, supports video frame rates at 30frame/s, twice the requirement of today's mobile phones.
Output modes include YUV (at 8 or 16bit) in ITU-R BT-656 or RGB formats.
The versatile high performance output is designed for minimum impact on other system functions by allowing direct memory bus interface or connection to an external video processor.
The high performance memory bus interface is designed for image capture and video transfer rates of 56Mbyte/s, four times the rate of conventional 8bit "streaming video" transfer rates.
The device's output is also designed to interface directly with today's high performance memory devices - for high-quality streaming video, high-speed image capture, and fast image storage.
The low voltage at 1.8V interface also saves battery power and maximises valuable talk time.
The i.IM20 image coprocessor features embedded firmware designed to support Motorola automatic exposure technology, white balance, and automatic gain control.
The coprocessor is also designed to support programmable gamma correction, colour space conversion and versatile output interfaces.
The baseband host processor communication and control to the i.IM20 is selectable between I2C or SPI compatible interfaces.
A variety of functions are under host processor control and are engineered to enable the i.IM20 to easily switch between output format modes and to enable "on the fly" image resizing, with no external memory requirements.
The "window-of-interest" panning and zooming and subsampling is engineered to be digitally controlled by the host processor.
The highly flexible I/O is designed to support interface voltages from 1.8 to 3.3V and can be configured as a memory mapped peripheral or can connect to an external video processor in a streaming video mode.
The 1.8V memory bus capability is a distinctive feature in the industry today designed for exceptionally high performance and low power interfaces.
Samples of the i.IM20 are expected in April 2003, with volume production shipments expected in June 2003.
