Designed to work in conjunction with the company’s high performance 2 and 1.2MP image sensor devices, ON Semiconductor has unveiled a series of image co-processors. The AP020x series of co-processors enable a full range of complete solutions for automotive rear view and surround view cameras, including high dynamic range 1080p automotive camera systems.

The image co-processors incorporate an advanced HDR colour pipeline with adaptive local tone mapping. The AP0200, AP0201 and AP0202 support up to 2MP 1080p image sensors, and the AP0102AT supports up to 1.2MP 720p image sensors. All of the co-processors offer support for functional safety features ASIL levels A and B. They support 30fps operation at 1080p, 45fps at 960p and 60fps at 720p. They also support Ethernet or parallel output interfaces and incorporate I2C, SPI and GPIOs. Each has an operating temperature range from -40 to +105°C (ambient) and is fully AEC-Q100 qualified.

The AP020x family will be offered as combined tuned solutions with existing image sensors such as the 1MP AR0140AT, AR0132AT and AR0136AT, as well as the AR0230AT 2MP 1080p sensor. These combination solutions of sensor plus co-processor provide automotive Tier 1s with the widest range of options for multiple market segments, while speeding time-to-market.

The AP0200AT image co-processor is optimised for rear view cameras and offers Ethernet output. It also includes a spatial transform engine which enables lens distortion correction and de-warping, as well as a sophisticated overlay graphics engine.

The AP0201AT image co-processor also has Ethernet output and is aimed at Ethernet-based surround view.

The AP0202AT image co-processor is targeted at digital surround view and utilises a 24-bit parallel output.

The AP0102AT image co-processor is targeted at 1 MP/720p rear view cams and includes the STE and overlay graphics engine.

Sandor Barna, Vice President, Automotive Imaging and Scanning Division, ON Semiconductor, commented: “With the announcement of these automotive co-processors, ON Semiconductor expands its position to supply leading global automotive customers with an even wider range of complete camera solutions for both high performance 1080p and 720p video. To specifically address customer requirements, we have added higher resolution, multiple interfaces and new automotive-targeted features such as ASIL support.”

The AP0200AT, AP0201AT, AP0202AT and AP0102AT are all offered in a VFBGA-100 package and are sampling now. These parts will be available in mass production in 3Q15.
