The MT9T031 is a 1/2‑inch QXGA‑format CMOS image sensor offering a 2048 × 1536 pixel array and a variety of camera functions such as windowing, column/row skip, and snapshot mode. It targets high‑resolution network cameras, PTZ cameras, and security video cameras that also need still‑image capability.
Key features include a simple two‑wire serial interface for programming, 10‑bit on‑chip ADC, programmable gain and black‑level calibration, and flexible windowing that supports multiple resolutions from QXGA down to VGA. Electrical specifications provide a 3.0 V–3.6 V supply range, 228 mW typical power consumption, and a maximum data rate of 48 Mp/s at 48 MHz.
