High-speed, high dynamic range CMOS image sensor operates in extreme conditions to provide safety and convenienceBOISE, Idaho & DETROIT—(BUSINESS WIRE)—Oct. 18, 2004— Micron Technology, Inc., (NYSE: MU) today announces commercial sampling of its new MT9V022 DigitalClarity(TM) high speed, wide-VGA high-performance image sensor featuring Micron's proprietary TrueSNAP(TM) ("Shutter Node Active Pixel") global shutter technology. Intended specifically for the rapidly expanding and demanding automotive sector, the MT9V022 boasts a global shutter (simultaneous total-pixel exposure system), enhanced near infrared (NIR) sensitivity, and high dynamic range. The MT9V022 is a true single-source solution targeted for the "scene understanding" needs -- both interior and exterior -- of the automotive industry and other low-cost embedded scene processing applications.
Micron's MT9V022 packs advanced performance specifications in a single VGA sensor designers could only have wished for a few years ago. The 1/3-inch monochrome (or color) low-power wide-VGA image sensor features an active pixel array format of 750(H) x 480(V) pixels designed to capture a "letter-box" image. The 6.0 micron x 6.0 micron pixels feature an advanced programmable piece wise linear architecture, enabling extremely high dynamic range (greater than 110dB) which simultaneously captures useable information in both bright sunlight and shadowed regions.
The MT9V022 performs at 60 frame-per-second (fps) at full resolution for stop-motion image-capture (up to 200 fps at lower resolutions) with the flexibility of either 10-bit or 8-bit parallel or serial LVDS data output. It also features enhanced near-IR sensitivity (greater than 40 percent QE at 850nm), on-chip timing, two-wire serial programmable interface, automatic gain and exposure control and auto black level calibration. Its exclusive TrueSNAP technology prevents image tearing common with competing rolling-shutter devices and enables true synchronized IR illumination for in-the-dark image capture. It has an extended operating temperature range of from -40 degrees C to +85 degrees C, and the dark current measurement rates only 10 percent saturated signal at +85 degrees C.
"During the last couple of years Micron has made extraordinary efforts to collect data from prospective customers to deliver what we believe is the industry's most complete 'ground-up' device designed to address the wide-ranging needs of the automotive image sensor business," stated Curtis Stith, who, as Director of Micron's Emerging Markets group, specializes in the automotive sector. "The requirements for an automotive imaging device are extreme. A sensor needs to be able to function in severe heat or freezing cold, in darkness or direct sunlight and under rapidly changing conditions. It has to function at high speed and capture, read and transmit reliable information instantaneously. We've collected design requirements from some of the world's leading engineers who are designing sophisticated equipment to enhance the driving experience and protect vehicle occupants. Equipped with that knowledge, we've strived to create a single imaging sensor delivering the market's most robust feature-set."
Typical applications for Micron's new MT9V022 sensor include: lane departure warning and guidance products, driver drowsiness detection systems, occupant sensing equipment for passenger and driver "smart air-bag" deployment, blind spot detection cameras (front, back and side systems) and general security and driver convenience.
The MT9V022 makes a perfect companion to the MT9V111 VGA (Industrial Temperature) SOC image sensor, also being sampled for automotive use. The device, among the best selling VGA sensors for mobile handsets and Smartphones due to its' ability to capture crisp images in low-light situations, works equally well for automotive "visual display" purposes such as rear- and side-viewing cameras. The MT9V111 SOC sensor was introduced in February 2004 and is in volume production at Micron's Boise-based manufacturing facility.
