ON Semiconductor has introduced the AR0234CS 2.3 Mp CMOS image sensor with global shutter technology. The high-performance sensor is designed for a variety of applications including machine vision cameras, AR/VR/MR headsets, autonomous mobile robots (AMRs) and barcode readers.

The AR0234CS captures 1080p video and single frames operating up to 120 frames per second (fps). With its shutter efficiency, the 2.3 Mp sensor produces crisp and clear images by minimising frame-to-frame distortion in high-speed scenes and reducing the motion artifacts other image sensors experience.

The AR0234CS sensor’s innovative pixel architecture delivers high dynamic range needed to support lighting conditions from the darkness of night to bright sunlight. The low noise and improved low-light response makes it suitable for applications spanning across consumer, commercial & industrial IoT, and the extended operating temperature range makes it deployable in challenging outdoor conditions.

“The need for quality image sensing is increasing, as more manufacturers are automating with vision-based expert systems,” said Gianluca Colli, Vice President and General Manager, Industrial and Consumer Sensor Division (ICSD) Group at ON Semiconductor. “That demand requires optimising size, performance and power of the image sensor. ON Semiconductor is one of the first manufacturers to recognise and respond to this need with the AR0234CS.”

Other advanced features of the AR0234CS include: programmable regions of interest with on-chip histogram, auto exposure control and 5x5 statistics engine, fully integrated strobe illumination control, a flexible row and column skip mode, along with horizontal and vertical mirroring, windowing and pixel binning.

Together with the AP1302 Image Signal Processor (ISP), the AR0234CS delivers a comprehensive camera system that can be designed and developed quickly for fast time-to-market. Additionally, system designers can access the DevSuite software to evaluate features and capabilities, configure and tune the sensor, and provide a ready-made output that is usable for further image processing.

The AR0234CS is offered in colour and mono variants, with zero or 28° CRA. Samples and development hardware are available now through local ON Semiconductor sales support representatives and authorised distributors.
