Description
Atmel’s AT71200M is a progressive scan sensor based on charge-coupled device (CCD) technology. It can be used in a wide range of applications thanks to operating mode flexibility, very high definition and high dynamic range. The nominal photosensitive area is made up of 2300 x 3500 useful pixels and is split into four independent zones that are driven separately by four independant four-phase clocksets. Thus the sensor can be used in up to 12 main modes. The large format and high definition make the device suitable for any application requiring precision and accuracy. The Bayer standard RGB color mosaic has been specially designed for colorimetric applications and the three colors balanced for a 3800K standard illuminant. Two serial registers and four independent output amplifiers offer a high-frequency functionality of up to 10 frames per second and a 12-bit dynamic range. 8M-pixel Color Image Sensor AT71200M Rev. 2133A–IMAGE–02/03

Note: 1. If not specified, all voltages are applied with respect to the substrate VSS. Electrical limits of applied signals are given in Table 5. SS or VDD, even temporarily, can permanently damage the output amplifier. Due to MPP mode or negative voltages, image zone gates and region of interest gates do not include ESD protection. on conductive layer used for shipment. Table 5. Maximum Applied Voltages(1)
