Advanced features and exceptional image quality minimise processing needs, resulting in a faster and more cost effective camera system

Meeting the needs of commercial, consumer and industrial applications with respect to superior image quality in challenging lighting conditions is the new AR0821CS, a 1/1.7 inch 8.3 MP CMOS digital image sensor with rolling shutter and embedded High Dynamic Range (eHDR) technology. Applications include scanners/readers, machine vision cameras, high-end drones, dashboard cameras and smart building surveillance/security systems.

The AR0821CS delivers 4K video with 8.3 MP resolution at 60 fps while consuming very low power. The advanced sensor includes a 2.1 µm DR−Pix backside illuminated (BSI) pixel design, which enables high quantum efficiency, as well as on-chip HDR (eHDR) technology for best-in-class dynamic range over 140 dB. The high quality image data minimises processing needs, resulting in a faster and more cost effective camera system.

The superior pixel design of the AR0821CS provides detailed image data even in bright daylight or low light conditions. With multiple subsampling modes, the AR0821CS optimises the amount of data transmitted to provide images at a faster rate as needed by the intended application.

The AR0821CS is supported by the AP1302 co-processor, an image signal processor (ISP) and system-on-chip (SoC) devices. Furthermore, the DevSuite software facilitates the development of AR0821CS-based camera systems, thus enabling system developers to complete their camera designs with minimal effort and launch their products to market quickly.

Alongside onsemi development resources, the AR0821CS has been designed into Basler’s dart family of area scan camera modules. The dart camera series enables a wide range of image processing applications and offers the latest machine vision technology in a small format.

“The integration of the new AR0821CS sensor from onsemi into our dart camera family is a significant step towards having a superior solution component for customer projects with HDR requirements. We have already noticed that the high-performance sensor is important for the successful implementation of new applications in light-sensitive conditions,” said Malene Fricke, Head of Module Business at Basler.

The AR0821CS is now in production and available through local onsemi sales support and authorised distributors.
