ON Semiconductor Launches Low‑Power, High‑Frame‑Rate ARX3A0 Image Sensor for Intelligent Vision

ON Semiconductor has introduced the ARX3A0 digital image sensor, engineered for advanced intelligent vision systems. The 0.3 MP sensor delivers a 1:1 aspect ratio and supports up to 360 fps, offering the speed of a global shutter while retaining the sensitivity and responsiveness of a back‑side illuminated (BSI) rolling‑shutter design.

Its compact, square footprint and high frame rate make the ARX3A0 ideal for machine vision, AI, and AR/VR applications—including eye‑tracking modules in head‑mounted displays where a 1/10‑inch form factor enables ultra‑thin, low‑profile solutions. The 3.5 mm die maximizes field‑of‑view, ensuring robust image capture even in tight spaces.

Power efficiency is a key differentiator. The sensor draws under 19 mW at 30 fps and drops to 2.5 mW at 1 fps, thanks to intelligent power‑management features that wake from a low‑power state when motion or lighting changes are detected. This allows the sensor to serve as the primary wake source for the camera system, delivering significant overall power savings.

The monochrome array—560 × 560 active pixels—leverages ON Semiconductor’s NIR+ technology, providing exceptional near‑infrared sensitivity for low‑light and invisible‑light scenarios. This enhances performance in environments where conventional visible‑light imaging falls short.

The ARX3A0 is available in chip‑scale package and reconstructed wafer‑die formats. Evaluation boards powered by ON Semiconductor’s PC‑based DevWare system, along with prototype modules, are available through the company and its authorized distributors.
