General Description
The ON Semiconductor AR0542 is a 1/4-inch CMOS active-pixel digital image sensor with a pixel array of 2592H x 1944V (2608H x 1960V including border pixels). It incorporates sophisticated on-chip camera functions such as windowing, mirroring, column and row skip modes, and snapshot mode. It is programmable through a simple two-wire serial interface and has very low power consumption.

FEATUREs
• Low dark current
• Simple two-wire serial interface
• Auto black level calibration
• Support for external LED or Xenon flash
• High frame rate preview mode with arbitrary 
   down-size scaling from maximum resolution
• Programmable controls: gain, horizontal and vertical
   blanking, auto black level offset correction,
   frame size/rate, exposure, left–right and top–bottom
   image reversal, window size, and panning
• Data interfaces: parallel or single/dual lanes serial
   mobile industry processor interface (MIPI)
• On-die phase-locked loop (PLL) oscillator
• Bayer pattern down-size scaler
• Superior low-light performance
• Integrated position and color-based shading
   correction
• 7.7 Kb one-time programmable memory (OTPM) for
   storing shading correction coefficients of three light
   sources and module information
• Extended Flash duration that is up to start of frame
   readout
• On-chip VCM driver
