ON Semi Announces Next Generation Automotive Sensor with LED Flicker Mitigation and ASIL B Support

BusinessWire: ON Semiconductor announces sampling of the LED Flicker Mitigation (LFM) technology in a new 2.3MP CMOS sensor for ADAS applications. Capable of capturing 1080p HDR video, the AR0231AT also includes features that support Automotive Safety Integrity Level B (ASIL B).

The LFM technology (patent pending) eliminates high frequency LED flicker from traffic signs and vehicle LED lighting and allows Traffic Sign Reading algorithms to operate in all light conditions. The AR0231AT has a 1/2.7-inch optical format and a 1928(H) x 1208(V) active pixel array. It uses the latest 3.0um BSI pixel with DR-Pix dual conversion gain technology. It captures images in linear, HDR or LFM modes, and offers frame-to-frame context switching between modes.

The new device offers up to 4-exposure HDR, capturing more than 120 dB dynamic range with superior noise performance. The AR0231AT is capable of multi-camera synchronization support to ease implementation in vehicle applications with multiple sensor nodes, and user programmability is achieved via a simple two-wire serial interface. It also has multiple data interfaces including MIPI, parallel and HiSPi. Other key features include selectable automatic or user controlled black level control, spread-spectrum input clock support and multiple color filter array options.

Features that support LFM and ASIL B in a 2.3 MP, 1080p BSI image sensor represent a state of the art combination ideal for high performance automotive ADAS cameras,” said Alvin Wong, senior director, Automotive Imaging and Scanning Division at ON Semiconductor.

The AR0231AT engineering samples are available now. It will be available in mass production in 2016.

    If yes, the problem is not fully resolved.
