Overview
This document describes the interfacing and the driving of the LUPA-4000 image sensor. This 4 mega-pixel CMOS active pixel sensor features synchronous shutter and a maximal frame-rate of 15 fps in full resolution. The readout speed can be boosted by means of sub sampling and windowed Region Of Interest (ROI) readout. High dynamic range scenes can be captured using the double and multiple slope functionality.

Main features
The main features of the image sensor are identified as:
• 2048 x 2048 active pixels (4M pixel resolution)
• 12 µm2 square pixels (based on the high-fill factor active
   pixel sensor technology of FillFactory (US patent No.
   6,225,670 and others))
• Peak QE x FF of 37.50%
• Optical format: 24,6 mm x 24,6 mm
• Pixel rate of 66 MHz using a 33 MHz system clock
• Optical dynamic range: 66 dB (2000:1) in single slope
   operation and up to 90 dB in multiple slope operation
• 2 On-chip 10 bit, 33 MSamples/s ADC
• Full snapshot shutter
• Random programmable windowing and sub-sampling
   modes
• 127-pin PGA package
• Binning (Voltage averaging in X-direction)
• Programmable read out direction (X and Y)
