According to ON Semiconductor, the industry's first 1/1.7" 2.1 megapixel CMOS image sensor has been launched. It features the company's newly developed 4.2μm Back Side Illuminated (BSI) pixels - the AR0221 delivers low light sensitivity for industrial applications.

The AR0221 offers 3-exposure line-interleaved High Dynamic Range (HDR) with a sensor resolution of 1,936Hx1,096V, supporting frame rates of 1080p at 30fps and a Signal-Noise Ratio (SNR) across visible and near-infrared wavelengths. Its 16:9 ratio with colours and high contrast make it suitable for demanding industrial applications.

Gianluca Colli, Vice President and General Manager, Consumer Solution Division of Image Sensor Group at ON Semiconductor said: “The AR0221 represents the industry’s best CMOS image sensor in this class, thanks to its outstanding low light sensitivity and SNR performance. By including features like windowing, auto black level correction and an onboard temperature sensor, ON Semiconductor has produced an image sensor that will enable a new generation of security and surveillance cameras.”

The sensor offers dual data interfaces in the form of 4-lane MIPI CSI-2 and HiSPi SLVS.

Designed to meet industrial-grade specifications, the AR0221 can operate in harsh outdoor environments where operating temperatures can range between -30°C and +85°C.

Packaged in a durable, reliable and robust iBGA package with anti-reflection coating on its cover glass, the AR0221 is programmable through a simple two-wire serial interface.
