FRAMOS: 5 Megapixel CMOS backside illuminated image sensor

The new ON Semiconductor AR0521 is a 1/2.5” image sensor with a 5 Megapixel resolution, offering 60 fps for excellent video performance. The 2.2 µm Back Side Illuminated pixel technology enables clear, sharp digital pictures while the sensor’s ability to capture both continuous video and single frames makes it the perfect choice for security applications. A demo kit is available for the AR0521 along with additional services provided by the global imaging experts at FRAMOS.

The AR0521 captures images in either linear or high dynamic range modes with rolling shutter readouts and includes additional functions such as binning and subwindowing in both video and single frame modes. It is designed for both low light and high dynamic range performance, with line interleaved T1/T2 readout that support off chip HDR algorithms in an ISP chip.

In addition, the excellent image quality is supplemented by several digital processing functions, including digital gain, dynamic defect correction and a digital shading correction block that compensates for color/brightness shading that is introduced by the lens and the sensor’s chief ray angle curve mismatch. The full resolution image can be outputted at 60 frames per second in linear mode and 30 fps in line interleaved HDR mode output through either the MIPI or HiSPi ports. The maximum data rate for MIPI is 1.2 Gb/second and 1.0 Gb/second for HiSPi. The AR0521 is designed to operate over a wide ambient temperature range of -30 to +85°C which aligns with a wide range of applications in rough environments. It also supports advanced line synchronization controls for multi-camera (stereo) support. Evaluation samples of color sensors are now available.

Industry and product experts at FRAMOS are available to support customers with the integration of these new sensors in their applications and projects. In addition, FRAMOS provides services like development support, customization, and logistics that speed development and improve time to market for all vision products.
