Cypress Semiconductor Corp. has started the commercial sampling of a high-sensitivity, high-speed SXGA (super extended graphics array) resolution CMOS image sensor. The 1.3Mpixel LUPA-1300-2 sensor is the industry's first to offer a triggered and pipelined synchronous shutter and on-chip digital LVDS outputs. Developed for machine vision and motion analysis applications, the image sensor features a high frame rate of 500fps and windowing capability that delivers undistorted images and fast readout.

The LUPA-1300-2 features a fully synchronous snapshot shutter, making it possible to read one image while the next is being acquired and to capture moving objects without distortion. The sensor has 12bit, 10bit digital LVDS outputs that allow image data to be transferred over longer distances on the circuit board, thus simplifying layout. The windowing capability enables the user to read out only regions of interest in the image, increasing the effective frame rate. It also has a multiple slope capability to maintain good contrast in shadowed regions without saturating bright areas in scenes with a high contrast ratio.

"The combination of exceptionally high sensitivity, fast frame rate, snapshot shutter mode and digital LVDS outputs offered by the LUPA-1300-2 is unmatched by other SXGA CMOS image sensors," said Cliff Drowley, VP of Cypress's image sensor business unit. "Cypress is committed to meeting market demand for innovative high-speed image acquisition solutions with higher frame rates and more integrated features for a wide range of applications, including motion analysis, robotics, tracking, industrial inspection and metrology."

The LUPA-1300-2 has 1,280 x 1,024pixels with 14?m x 14?m pixel size. The image sensor integrates a programmable offset and gain amplifier for each channel of the LVDS outputs. Each channel runs at a 61MHz pixel rate, which results in 500fps frame rate at full resolution. Higher frame rates can be achieved by windowed or sub-sampled readout modes, which are all programmable over SPI. All internal exposure and read-out timings are generated by an on-board sequencer. The intra-scene dynamic range can be increased by using the flexible multiple slope operation mode. The LUPA-1300-2 also features a 10bit on-chip ADC for digital output and on-chip timing control for easy application development. The image sensor, developed at Cypress's Mechelen, Belgium facility, is currently available in monochrome with an RGB version in development.

Prototype samples of the LUPA-1300-2 are available now with production devices expected in Q3 2008.
