1/1.8-Inch CMOS Digital
Image Sensor
General Description
ON Semiconductor AR0220AT is a 1/1.8−inch CMOS digital image
sensor with a 1828 H x 948 V active−pixel array. This advanced
automotive sensor captures images in either linear, or high dynamic
range, with rolling−shutter readout. AR0220AT is optimized for both
low light and challenging high dynamic range scene performance,
with a 4.2 mm BSI pixel and on−sensor 120 dB HDR capture
capability. The sensor includes flexible functions such as in−pixel
binning, windowing, and both video and single frame modes. The
sophisticated sensor fault detection features and embedded data on
AR0220AT are designed to enable camera ASIL B compliance. The
device is programmable through a simple two−wire serial interface,
and supports MIPI output interface.

General Description
The ON Semiconductor AR0220AT can be operated in its
default mode or programmed for frame size, exposure, gain,
and other parameters. The default mode output is a 1820 x
940 resolution image at 60 frames per second (fps). In linear
mode, it outputs 12−bit raw data, using serial MIPI output
ports. In high dynamic range mode, it outputs 12−bit, 14−bit
or 16−bit compressed or 20−bit linearized data using the
MIPI port. The device may be operated in video (master)
mode or in single frame trigger mode.
FRAME_VALID, LINE_VALID and pixel clock can be
programmed to output by GPIO pins in serial mode.
The AR0220AT includes additional features to allow
application−specific tuning: windowing and offset, auto
black level correction, and on−board temperature sensor.
Optional register information and histogram statistic
information can be embedded in first and last two lines of the
image frame.
The sensor is designed to operate in a wide temperature
range (−40°C to +125°C junction).
Functional Overview
The AR0220AT is a progressive−scan sensor that
generates a stream of pixel data at a constant frame rate. It
uses an on−chip, phase−locked loop (PLL) that can be
optionally enabled to generate all internal clocks from a
single master input clock running between 6 and 50 MHz.
The maximum output pixel rate is 85.5 Mp/s. Figure 1 shows
a block diagram of the sensor.

Output
User interaction with the sensor is through the two−wire
serial bus, which communicates with the array control,
analog signal chain, and digital signal chain. The core of the
sensor is a 1.7 Mp BSI Active−Pixel Sensor 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 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). The sensor also offers a high dynamic range
mode of operation where multiple images are combined
onchip to produce a single image at 20−bit per pixel value.
A compressing mode is further offered to allow this 20−bit
pixel value to be transmitted to the host system as a 12− or
14− or 16−bit value with close to zero loss in image quality.
The pixel data are output at a rate of up to 85.5 Mp/s.
Features Overview
The AR0220AT has a wide array of features to enhance
functionality and to increase versatility. A summary of
features follows. Please refer to the AR0220AT Developer
Guide for detailed feature descriptions, register settings, and
tuning guidelines and recommendations.
• Operating Modes
The AR0220AT works in master (video), trigger (single
frame), or Auto Trigger modes. In master mode, the
sensor generates the integration and readout timing. In
trigger mode, it accepts an external trigger to start
exposure, then generates the exposure and readout
timing. The exposure time is programmed through the
two−wire serial interface for both modes.
• Window Control
Configurable window size and blanking times allow a
wide range of resolutions and frame rates. Digital

binning and skipping modes are supported, as are
vertical and horizontal mirror operations.
• Context Switching
Context switching may be used to rapidly switch
between two sets of register values. Refer to the
AR0220AT Developer Guide for a complete set of
context switchable registers.
• Gain
The AR0220AT can be configured for analog gain of
up to 4x, and digital gain of up to 8x.
• MIPI
The AR0220 image sensor supports 4−line MIPI CSI−2
D−PHY
• PLL
An on chip PLL provides reference clock flexibility and
supports spread spectrum sources for improved EMI
performance.
• Reset
The AR0220AT may be reset by a register write, or by
a dedicated input pin.
• Output Enable
The AR0220AT output pins may be tri−stated using
dedicated register bits.
• Temperature Sensor
• Black Level Correction
• Row Noise Correction
• Digital Correlated Double Sampling (CDS)
• Test Patterns
Several test patterns may be enabled for debug
purposes. These include a solid color, color bar, fade to
gray, and a walking 1s test pattern.
