On Semiconductor is expanding its 1/3-inch, 1 megapixel image sensor portfolio with early sampling of the company’s first backside illuminated (BSI) sensor technology for the automotive imaging market.

The new sensor technology delivers four times better low light signal-to-noise ratio, a 40 per cent increase in visible light sensitivity, and more than 60 per cent improvement in near infrared performance than the current AR0132AT CMOS image sensor for advanced driver assistance systems (ADAS).

The first product to incorporate this new technology will be the AR0136AT 1/3-inch optical format CMOS digital image sensor with 1280 x 960 pixel resolution, and 3.75µm BSI pixels. The AR0136AT supports linear and high dynamic range modes, in a single chip HDR solution, with a 120dB dynamic range in HDR mode. It has an output pixel rate of 74.25MP/s (maximum), which results in a frame rate of 45fps at 960p resolution, and 60fps at 720p resolution. It has an operating junction temperature range of -40°C to +125°C and will be fully qualified to AEC-Q100.

Engineering samples will be available in Q3 of 2015, with mass production planned for early 2016.
