General Description
The ON Semiconductor AR0141CS is a 1/4-inch CMOS
digital image sensor with an active-pixel array of
1280Hx800V. It captures images in linear mode, with a
rolling-shutter readout. It includes sophisticated cam-
era functions such as in-pixel binning, windowing and
both video and single frame modes. It is designed for
low light scene performance. It is programmable
through a simple two-wire serial interface. The
AR0141CS produces extraordinarily clear, sharp digital
pictures, and its ability to capture both continuous
video and single frames makes it the perfect choice for
a wide range of applications, including surveillance
and HD video.

AR0141CS: 1/4-Inch Digital Image Sensor
.Functional Overview
Figure 2:
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 offset correction and gain), and then through an analog-
to-digital converter (ADC). The output from the ADC is a 12-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).

Notes:
1. All power supplies must be adequately decoupled.
2. ON Semiconductor recommends a resistor value of 1.5k, but a greater value may be used for
slower two-wire speed.
3. The parallel interface output pads can be left unconnected if the serial output interface is used.
4. ON Semiconductor recommends that 0.1F and 10F decoupling capacitors for each power supply
are mounted as close as possible to the pad. Actual values and results may vary depending on lay-
out and design considerations. Check the AR0141CS demo headboard schematics for circuit recom-
mendations.
5. ON Semiconductor recommends that analog power planes are placed in a manner such that cou-
pling with the digital power planes is minimized.
6. I/O signals voltage must be configured to match VDD_IO voltage to minimize any leakage currents.

AR0141CS: 1/4-Inch Digital Image Sensor
Differentiation from AR0141CS
Default Readout Order
By convention, the sensor core pixel array is shown with pixel (0,0) in the top right
corner (see Figure 6). This reflects the actual layout of the array on the die. Also, the first
pixel data read out of the sensor in default condition is that of pixel (0, 0).
When the sensor is imaging, the active surface of the sensor faces the scene as shown in
Figure 8. When the image is read out of the sensor, it is read one row at a time, with the
rows and columns sequenced as shown in Figure 8.
