GENERAL DESCRIPTION
The ON Semiconductor AR0833 is a 1/3.2-inch BSI
(back side illuminated) CMOS active-pixel digital image
sensor with a pixel array of 3264 (H) x 2448 (V) (3280 (H)
x 2464 (V) including border pixels). It incorporates
sophisticated on-chip camera functions such as mirroring,
column and row skip modes, and context switching for zero
shutter lag snapshot mode. It is programmable through a
simple two-wire serial interface and has very low power
consumption.
The AR0833 digital image sensor features ON
Semiconductor’s breakthrough low-noise 1.4
μm
pixel
CMOS imaging technology that achieves near-CCD image
quality (based on signal-to-noise ratio and low-light
sensitivity) while maintaining the inherent size, cost, and
integration advantages of CMOS.
The AR0833 sensor can generate full resolution image at
up to 30 frames per second (fps). An on-chip
analog-to-digital converter (ADC) generates a 10-bit value
for each pixel.

FUNCTIONAL OVERVIEW
In order to meet higher frame rates in AR0833 sensor, the
architecture has been re-designed. The analog core has a
column parallel architecture with 4 data paths. Digital block
has been re-architected to have 4 data paths.

The chip is targeted to meet SMIA 85 module size. As a
result, the final die size is 6.86 mm x 6.44 mm (singulated)
which would fit in the intended module with two-sided pad
frame.

Figure 1. Top Level Block Diagram
The core of the sensor is an 8 Mp active-pixel array. The
timing and control circuitry sequences through the rows of
the array, resetting and then reading each row in turn. In the
time interval between resetting a row and reading that row,
the pixels in the row integrate incident light. The exposure
is controlled by varying the time interval between reset and
readout. Once a row has been read, the data from the
columns is sequenced through an analog signal chain
(providing gain), and then through an ADC. The output from
the ADC is a 10-bit value for each pixel in the array. The
ADC output passes through a digital processing signal chain
(which provides further data path corrections and applies
digital gain).
The pixel array contains optically active and
light-shielded (“dark”) pixels. The dark pixels are used to
provide data for on-chip offset-correction algorithms
(“black level” control).
The sensor contains a set of control and status registers
that can be used to control many aspects of the sensor
behavior including the frame size, exposure, and gain
setting. These registers can be accessed through a two-wire
serial interface.
The output from the sensor is a Bayer pattern; alternate
rows are a sequence of either green and red pixels or blue and
green pixels. The offset and gain stages of the analog signal
chain provide per-color control of the pixel data.
A flash output signal is provided to allow an external
xenon or LED light source to synchronize with the sensor
exposure time. Additional I/O signals support the provision
of an external mechanical shutter.
Pixel Array
The sensor core uses a Bayer color pattern, as shown in
Figure 2. The even-numbered rows contain green and red
pixels; odd-numbered rows contain blue and green pixels.
Even-numbered columns contain red and green pixels;
odd-numbered columns contain blue and green pixels.
