Imaging SOCs from ON Semiconductor
ON Semiconductor has announced two new 1.0 Mp CMOS image-sensing products. The company says the components provide a complete solution with the image sensor and processing functionality integrated within a low-power system-on-chip (SoC) that simplifies and speeds adoption in applications such as rear- and surround-view cameras. PCB real estate savings of greater than 30% can be achieved compared to conventional solutions.
The AS0140 and AS0142 imaging devices can be used to improve driver comfort, convenience, and safety through a range of advanced driver assistance systems (ADAS), according to the company. The chips are both 1/4-inch format devices capable of supporting 45 fps throughput at full resolution or 60 fps at 720 p. Key features include distortion correction, multi-color overlays, and both analog (NTSC) and digital (Ethernet) interfaces. Both SoC devices achieve enhanced image quality via adaptive local tone mapping (ALTM) 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 devices provide multi-camera synchronization support.
“These devices provide engineers with complete SoC camera solutions that combine low power operation and high dynamic range with minimal impact in relation to PCB footprint and overall bill-of-materials cost,” stated Ross Jatou, Vice President and General Manager of the Automotive Imaging Solutions Division at ON Semiconductor. “This means that they are able to meet the imaging demands of car manufacturers from both a logistical and performance perspective. Most current solutions still rely on inefficient discrete arrangements with a separate image sensor and image processor, or are SoCs with relatively limited functionality.”
Both devices, when running at 30 fps in high dynamic range (HDR) mode, consume 530 mW. Their operating temperature range is -40°C to +105°C, making them suitable for use in automotive environments. Engineering samples are available now. The AS0140 will be in production in 4Q17, and the AS0142 will be in production in 1Q18.
