Motorola 1.3 Mp ImageMOS

Jan 2, 2001 at 04:00 GMT

Motorola today introduced the MCM20027 1280 x 1024 CMOS image sensor. Dubbed "camera-on-a-chip" this new sensor integrates the PGA (amplifier) and ADC (analog to digital converter) onto a single chip (as do all CMOS sensors). "Targeted at cost-sensitive digital still cameras, video systems and other imaging applications, the MCM20027 is manufactured using Motorola's ImageMOS technology."

Motorola ImageMOS Sensor Provides "Camera-on-a-Chip''

Advanced Image Sensor Is a Low-Cost Solution for Digital Cameras and Other Imaging Products
PHOENIX--(BUSINESS WIRE)--Jan. 2, 2001--An image sensor that provides 1.3 megapixel resolution for manufacturers of imaging products such as digital still cameras, video systems and other imaging applications was announced by Motorola Inc. (NYSE:MOT - news) today.

As the low-cost digital imaging market rapidly expands from VGA (640 x 480 pixel resolution) to SXGA (1280 x 1024 pixel resolution) products, Motorola's introduction of the MCM20027 SXGA image sensor brings a new cost-effective option to manufacturers of these megapixel imaging applications. Implemented using Motorola's ImageMOS(TM) process, the MCM20027 is a smart, DigitalDNA(TM) imaging solution containing both analog and digital signal processing -- making it a cost-effective "camera-on-a-chip.''

Targeted at cost-sensitive digital still cameras, video systems and other imaging applications, the MCM20027 is manufactured using Motorola's ImageMOS technology. This wafer process uses patented pinned photo diode and unique pixel design technology from Motorola and Kodak. Motorola's new image sensor features a unique pixel design, which provides improved fill factor versus die size. The quantum efficiency of the image sensor minimizes noise while maintaining excellent light sensitivity across the visible spectrum.

"The MCM20027 strengthens Motorola's position as a leading supplier of CMOS image sensors, and expands the company's CMOS image sensor portfolio from several custom and standard products to include a high-quality 1.3 megapixel SXGA image sensor,'' stated Larry Arbaugh, manager of Motorola's Image Capture Operations. "This will enable camera manufacturers to develop higher-quality consumer products at affordable prices.''

Technical Features

The MCM20027 is designed as a 1280 x 1024 pixel progressive scan image sensor with integrated correlated double sampling (CDS), programmable gain amplifier (PGA) and analog-to-digital converter (ADC). The 6 um by 6 um pixel pitch provides light sensitivity to 3 LUX at 10 frames per second. The MCM20027 incorporates an integrated Bayer RGB color filter array and microlenses for maximum sensitivity. The sensor outputs 10-bit Bayer encoded RGB data with all appropriate frame-timing signals.

CMOS image sensor technology provides for higher levels of integration, lower power consumption and a single-supply voltage versus conventional CCD (charged coupled device) sensors. The MCM20027 requires less than 250 mW of power and has a power-savings mode of 100 uW for improved performance in power-sensitive battery applications. The sensor architecture supports programmable "window-of-interest'' for pan-and-scan, digital zoom and other sub-sampling modes required for next-generation digital camera products.

Pricing and Availability

Motorola plans to begin offering samples of the MCM20027 image sensor in January 2001. The suggested resale price of the MCM20027 is $22 in 10,000-piece quantities, dependent upon the quantity ordered.
