General Description
The onsemi MT9P031 is a 1/2.5−inch CMOS active−pixel digital
image sensor with an active imaging pixel array of 2592 H x 1944 V. It
incorporates sophisticated camera functions on−chip such as
windowing, column and row skip mode, and snapshot mode. It is
programmable through a simple two−wire serial interface.
The 5 Mp CMOS image sensor features onsemi’s breakthrough
low−noise CMOS imaging technology that achieves CCD image
quality (based on signal−to−noise ratio and low−light sensitivity)
while maintaining the inherent size, cost, and integration advantages
of CMOS.

Features
• High Frame Rate
• Superior Low-light Performance
