M For the latest datasheet, please visit www.onsemi.com Features • Array Format (5:4): 1,280H x 1,024V (1,310,720 active  pixels). Total (incl. dark pixels): 1,312H x 1,048V  (1,374,976 pixels)  • Frame Rate: 30 fps progressive scan; programmable • Shutter: Electronic Rolling Shutter (ERS) • Window Size: SXGA; programmable to any smaller  format (VGA, QVGA, CIF, QCIF, etc.) • Programmable Controls: Gain, frame rate, frame size Applications • Digital still cameras • Digital video cameras • PC cameras General Description The ON Semiconductor MT9M001 is an SXGA-format  with a 1/2-inch CMOS active-pixel digital image sen- sor. The active imaging pixel array of 1,280H x 1,024V. 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.  This megapixel CMOS image sensor features ON Semi- conductor’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. Table 1: Key Performance Parameters The sensor can be operated in its default mode or pro- grammed by the user for frame size, exposure, gain set- ting, and other parameters. The default mode outputs  an SXGA-size image at 30 frames per second (fps). An  on-chip analog-to-digital converter (ADC) provides 10  bits per pixel. FRAME_VALID and LINE_VALID signals  are output on dedicated pins, along with a pixel clock  that is synchronous with valid data.
