ON Semiconductor has announced the release of two highly integrated 1.0 Megapixel (Mp) CMOS image sensing products. The new parts provide a complete solution with the new image sensor and processing functionality integrated within a low power system-on-chip (SoC) that simplifies and speeds adoption in applications like rear and surround view cameras. PCB real estate savings of greater than 30 percent can be achieved compared to conventional solutions comprised of sensor and processor components. This helps designers implement camera solutions without impacting vehicle styling or aesthetics.

The number of cameras and other image sensing technologies utilized on passenger vehicles continues to increase rapidly. Industry analyst predictions suggest annual shipments of cameras for use in cars will surpass 80 million units by 2020. Sensors that support the progression toward full autonomous driving represent one area of application. But imaging devices like the AS0140 and AS0142 can be used to improve driver comfort, convenience and safety through a growing range of Advanced Driver Assistance Systems (ADAS). Integrated sensors can provide vehicle designers with easy-to-implement solutions that support comprehensive and clear views of the vehicle surroundings for drivers.

The AS0140 and AS0142 are both ¨ù-inch format devices capable of supporting 45 fps throughput at full resolution or at 60 fps at 720 p. Key features are distortion correction, multi-color overlays and both analog (NTSC) and digital (Ethernet) interfaces. The SoC device achieves enhanced image quality by making use of the adaptive local tone mapping (ALTM) in order to eliminate facts that impinge on the acquisition process. The dynamic range of 93 decibels (dB) allows new devices to operate effectively in both high and low light applications. The AS0140 and AS0142 provide multi-camera synchronization support, which increased their value to automotive design engineers as the number of cameras installed on vehicles continues to rise.

Both new devices exhibit class-leading power efficiency; when running at 30 fps in high dynamic range (HDR) mode, they consume 530 milliwatts (mW). Operating temperature range is -40¢ªC to ¡¾105¢ªC, enhancing suitability for use in automotive environments.
