These image co-processors are intended to work with high dynamic range (HDR) 1080p automotive camera systems, and in particular, ON Semi’s 2 megapixel (MP) and 1.2 MP image sensor devices: the new AP020x series of co-processors enable a full range of complete solutions for automotive rear view and surround view cameras. Added features include higher resolution, multiple interfaces and new automotive-targeted features such as ASIL support.
The co-processors all incorporate an advanced HDR colour pipeline with adaptive local tone mapping (ALTM). The AP0200, AP0201 and AP0202 support up to 2 MP 1080p image sensors, and the AP0102AT supports up to 1.2 MP 720p image sensors. All of the co-processors offer support for functional safety features, Automotive Safety Integrity Level (ASIL) levels A and B. They support 30 frames/second (fps) operation at 1080p, 45 fps at 960p and 60 fps at 720p. They also support Ethernet or parallel output interfaces, and incorporate I²C, SPI (Serial Peripheral Interface) and general purpose input/outputs (GPIOs). Each has an operating temperature range of -40 °C to +105 °C (ambient) and is fully AEC-Q100 qualified.
The AP0200AT image co-processor is optimised for rear view cameras and offers Ethernet output. It also includes a spatial transform engine (STE) 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.
The AP020x family will be offered as combined tuned solutions with existing image sensors such as the 1-MP AR0140AT, AR0132AT and AR0136AT, as well as the AR0230AT 2-MP 1080p sensor. All come in a VFBGA-100 package. The AR0230AT is available in an IBGA-80. These parts will be available in mass production in 3Q15.
