BSI CMOS image sensor targets ADAS & viewing cameras

Expanding its highly-regarded 1/3" 1MP image sensor portfolio, ON Semiconductor has announced the company’s first BSI (BackSide Illuminated) sensor technology for the automotive imaging market. The sensor technology delivers four times better low light SNR, a 40% increase in visible light sensitivity and greater than 60% improvement in near infrared performance than the current market leading AR0132AT CMOS image sensor for ADAS.

“The advantages this BSI technology brings to the automotive market are exciting,” said Sandor Barna, Vice President, Automotive and Scanning Division, ON Semiconductor. “The state-of-the-art BSI devices based on this technology, that we currently have in early sampling, exhibit true industry-leading low light performance, and demonstrate our commitment to continued investment in automotive imaging technology.”

The first product to incorporate this new technology will be the AR0136AT 1/3" optical format CMOS digital image sensor with 1280x960 resolution and 3.75μm BSI pixels. It supports linear and HDR modes, in a single chip HDR solution, with a 120dB dynamic range in HDR mode. It has an output pixel rate of 74.25MP/second (maximum), which results in 45fps at 960p resolution and 60fps at 720p resolution.

The AR0136AT operates over a temperature range from -40 to +125°C and will be fully qualified to AEC-Q100. Engineering samples will be available in Q3 2015, with mass production planned for early 2016.
