Processor brings 1080p video to car rear-view mirrors

ON Semiconductor has developed a range of image co-processors to work with 1.2 and 2 megapixel image sensors specifically in automotive rear view and surround view cameras.

According to Sandor Barna, vice president at ON Semiconductor, the processor will support both 1080p and 720p video in automotive applications.

“We have added higher resolution, multiple interfaces and new automotive-targeted features such as ASIL support,” said Barna.

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.

The chips will be used 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 co-processors are designed to be used in combination with the firm’s image sensors such as the 1 MP AR0140AT, AR0132AT and AR0136AT, as well as the new AR0230AT 2 MP 1080p sensor.
