ONSemi’s New 2.1MP CMOS Sensor delivering Full HDR for Automotive and Security

AR0230AT sensor combines industry leading low-light capabilities with superior near-infrared performance and crisp and clear images with low noise.

ON Semiconductor, driving energy efficiency innovations, has introduced its latest high performance CMOS image sensor targeted for use in advanced video security cameras, especially targeted to the automotive industry. The AR0230AT image sensor is a 1/2.7 inch optical format device with high 105 decibel (dB) dynamic range that combines industry leading low-light capabilities with superior near-infrared (NIR) performance.

Sibel Yorulmaz, Line Manager at OnSemi’s distributor FRAMOS explains: “The AR0230AT produces extraordinarily clear, sharp digital pictures, and its ability to capture both continuous video and single frames makes it the perfect choice for a wide range of applications, including surveillance, HD video, and automotive scene viewing. With the extended operating temperature from -40°C to +105°C and the iBGA packing requiring less space and with lower thermal resistance it’s a great fit for automotive challenges.”

This image sensor enables the capture of full high-definition (Full HD) 1080p video data at a rate of 30 frames-per-second (fps) or even 60 fps for less quality surveillances tasks. It includes integrated support for HDR video, with improved motion compensation, advanced local tone mapping (ALTM), and digital lateral overflow (DLO) to minimize motion artifacts and enhance HDR color reproduction. This complete HDR functionality ensures fast time to market for new HDR 1080p camera designs. Additionally, the AR0230AT provides interleaved T1/T2 output for those using third-party ISP HDR support.

ON Semiconductor’s proprietary dual-conversion gain 3.0 micron (µm) DR-Pix™ pixel technology is used to enhance low light performance and broaden the dynamic range up to a maximum of 105 dB. The DR-Pix™ technology pixel provides two modes: a low conversion gain mode that is optimized to offer greater charge handling capacity in bright environments and a high conversion gain mode which delivers increased sensitivity and reduced readout noise in low light environments. Additional features include global reset release shutter mode, sophisticated on-board statistics engine, high-speed configurable context switching, automatic black level calibration (BLC), on-chip phase-locked loop (PLL) and temperature sensor. The AR0230CS came with both parallel and HiSPi interfaces and is offered in a 10mm x 10mm 80-pin iBGA package.
