onsemi AR0230CSSC00SUEA0: A 1/6-Inch 3 MP CMOS Digital Image Sensor for Advanced Vision Systems

The onsemi AR0230CSSC00SUEA0 is a high-performance, 1/6-inch CMOS digital image sensor designed to deliver exceptional image quality and advanced functionality for a wide range of consumer and industrial applications. This 3-megapixel (MP) sensor is engineered to meet the demanding requirements of modern machine vision, surveillance, and computational photography.

Key Features and Technical Specifications

At the core of the AR0230CS is a 3-megapixel (1928H x 1088V) active pixel array. This resolution provides a compelling balance between detail capture and processing efficiency, making it ideal for applications where both clarity and system performance are critical. The sensor utilizes advanced 3.0 μm back-side illuminated (BSI) pixel technology. This architecture significantly enhances performance by increasing the light collection efficiency, which is paramount for achieving high-quality images in challenging, low-light conditions.

The AR0230CS supports a versatile range of output interfaces. It can stream high-frame-rate data via a MIPI CSI-2 serial output interface (with 2 or 4 data lanes), the current standard for embedding cameras in mobile and compact devices. For legacy support or specific application needs, it also offers a parallel output option. The sensor operates from a single power supply and incorporates an on-chip phase-locked loop (PLL) for simplified system integration.

A defining characteristic of this sensor is its capability for simultaneous streaming of two different images from a single capture. This unique feature allows one output to be a high-dynamic-range (HDR) video stream while the other is a low-latency, processed YUV output. This is particularly valuable for automotive driver assistance systems (ADAS) and robotics, where real-time processing and analysis of high-dynamic-range scenes are required concurrently.

The AR0230CS also includes a comprehensive suite of on-chip statistical engines and automatic image control functions. These include automatic exposure control (AEC), automatic white balance (AWB), automatic black level compensation (ABLC), and defect correction. These features offload significant processing overhead from the host processor, simplifying system design and ensuring optimal image quality across varying environmental conditions.

Target Applications

The robust feature set of the onsemi AR0230CS makes it an excellent choice for:
