AR0821CS image sensor delivers in challenging light conditions

The AR0821CS image sensor from ONsemi provides high-quality images in challenging lighting conditions. These applications include scanners and/or 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 low power. The advanced sensor includes a 2.1 micro-Ohmn DR−Pix backside illuminated (BSI) pixel design exclusive to ONsemi, which enables high-quantum efficiency, as well as on-chip HDR (eHDR) technology that delivers dynamic range in excess of 140 dB.

A high-quality pixel design delivers detailed images 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 and by image signal processor (ISP) and system-on-chip (SoC) devices from ONsemi technology partners. The DevSuite software provides an integrated platform to develop AR0821CS-based camera systems. Within the DevSuite software, ONsemi provides custom firmware to enable system developers to complete their camera designs with minimal effort.

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 toward 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 is available through local ONsemi sales support and authorised distributors.

With a focus on automotive and industrial end-markets, ONsemi is accelerating change in megatrends such as vehicle electrification and safety, sustainable energy grids, industrial automation, and 5G and cloud infrastructure.
