The CIS2521AFxxxx is a large format, ultra-low noise CMOS image sensor intended for applications requiring high quality imaging under extremely low light conditions. The device features an array of 5 transistor (5T) pixels on a 6.5μm pitch with an active imaging area of 2560(H) x 2160(V) pixels. The CIS2521AF delivers extreme low-light sensitivity with read noise less than 2 electrons RMS, Quantum Efficiency (QE) above 55% and very low dark current. The sensor runs in Rolling and Global Shutter readout modes. The sensor has two ADC channels per column with one optimized for low light levels and the other optimized for high light levels, enabling high dynamic range data collection in a single image. The sensor supports userprogrammable row start/stop control for region of interest (ROI) readout. The sensor is housed in a 168-pin CLCC package (Scientific and Standard packages are shown above). These features, combined with 5.5 megapixel resolution and 100 fps imaging rates, make the CIS2521AF an imaging device ideally suited for a variety of low light-level camera applications including: security/surveillance, industrial, and medical.
