onsemi ARX3A0

The ARX3A0 digital image sensor with 0.3 Mega-Pixel (MP) resolution in a 1:1 aspect ratio. With up to 360 frames per second (fps) capture rate it can perform like a global shutter in many conditions but with the size, performance and responsivity benefits of being a Back-Side Illuminated (BSI) rolling shutter sensor. With its small size, square format and high frame rate, ARX3A0 is particularly suitable for emerging Machine Vision, Artificial Intelligence and AR/VR applications, as well as small supplemental security cameras.

The ARX3A0 CMOS image sensor was recognized among the best in machine vision today with a Bronze Innovation Award as part of the Vision Systems Design 2020 Innovators Awards program.
