Overview
Figure 1. LUPA4000 Photo
The LUPA4000 is a CMOS image sensor (CIS) with a 4.0
megapixel resolution 2048 x 2048 pixel format.
This document describes the interfacing and driving of the LUPA4000 image sensor. This 4 megapixel 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 sub-sampling and windowed ROI readout. High dynamic range scenes can be captured using the double and multiple
slope functionality.
The sensor uses a 3-wire SPI and is housed in a 127-pin ceramic PGA package. The LUPA4000 is available in mono and
color option.

1. All parameters are characterized for DC conditions after thermal equilibrium is established.
2. The maximum currents are peak currents which occur once per frame.
3. This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is recommended
that normal precautions be taken to avoid application of any voltages higher than the maximum rated voltages to this high−impedance circuit.

Pixel Array Drivers
The image sensor has on-chip drivers for the pixel array
signals The driving on system level is easy and flexible; the
maximum currents applied to the sensor are also controlled
on-chip. This means that the charging on sensor level is
fixed; the sensor cannot be overdriven externally. The
operation of the on-chip drivers is explained in Timing and
Readout of Image Sensor on page 13.
Column Amplifiers
The column amplifiers are designed for minimum power
dissipation and minimum loss of signal, resulting in multiple
biasing signals.
The column amplifiers have an integrated
‘voltage-averaging’ feature. In the voltage-averaging mode,
the voltage average between two columns is read out. In this
mode, only 2:1 pixels must be read out.
To achieve the voltage-averaging mode, an additional
external digital signal called voltage-averaging is required
in combination with a bit from the SPI.
Analog-to-Digital Converter
The LUPA4000 has two 10-bit flash ADCs running
nominally at 10 Msamples/s. The ADC block is electrically
separated from the image sensor. The inputs of the ADC
must be tied externally to the outputs of the output
amplifiers. If the internal ADC is not used, then the power
supply pins to the ADC and the I/Os must be grounded.
Even in this configuration, the internal ADCs are not able
to sustain the 66 Mpixel/sec provided by the output
amplifier when run at full speed.
One ADC samples the even columns and the second ADC
samples the odd columns. Although the input range of the
ADC is between 1 V and 2 V and the output range of the
analog signal is between 0.3 V and 1.3 V, the analog output
and digital input may be tied to each other directly. This is
possible because there is an on-chip level-shifter located in
front of the ADC to lift up the analog signal to the ADC
range.
Errata for Internal ADCs
Use external ADCs due to the limitation of the internal
ADC clock, not operational at system clock. No fix is
intended to resolve this limitation.

1. The internal ADC range is typically 50 mW lower than the external
applied ADC_VHIGH and ADC_VLOW voltages due to voltage
drops over parasitic internal resistors in the ADC.
ADC Timing
The ADC converts the pixel data on the falling edge of the
ADC_CLOCK, but it takes two clock cycles before this
pixel data is at the output of the ADC. This pipeline delay is
shown in Figure 6.
