Imaging SOCs Deliver Big Vision With Smaller Cameras

ON Semiconductor unleashes two highly integrated 1-Megapixel (Mp) CMOS image sensors that provide a complete solution with the image sensor and processing functionality integrated within a low power system-on-chip (SoC). This promises to simplify and accelerate adoption in applications such as rear and surround view cameras. Using the AS0140 and AS0142, PCB real estate savings of greater than 30% can be achieved compared to conventional solutions comprised of discrete sensor and processor components.


Both SoCs can be used to improve driver comfort, convenience and safety through a growing range of Advanced Driver Assistance Systems (ADAS). The AS0140 and AS0142 are both 1/4-inch format devices capable of supporting 45 fps throughput at full resolution or 60 fps at 720p.


Features include distortion correction, multi-color overlays and both analog (NTSC) and digital (Ethernet) interfaces. Both SoC devices achieve enhanced image quality by making use of the adaptive local tone mapping (ALTM) in order to eliminate artifacts that impinge on the acquisition process. Dynamic range of 93 dB allows new devices to operate effectively in both high and low light applications. The AS0140 and AS0142 provide multi-camera synchronization support which increases their value to automotive design engineers as the number of cameras installed on vehicles continues to rise.


Running at 30 fps in high dynamic range mode, both devices consume 530 mW. Operating temperature range is -40°C to +105°C. The AS0140 will be in production in 4Q17, and AS0142 will be in production in 1Q18. For more features and specs, datasheets for the AS0140 and AS0142 are available.
