General Description
ON Semiconductor's AR0237 is a 1/2.7-inch CMOS
digital image sensor with an active-pixel array of
1928Hx1088V. It captures images in either linear or
high dynamic range modes, with a rolling-shutter
readout. It includes sophisticated camera functions
such as in-pixel binning, windowing and both video
and single frame modes. It is designed for both low
light and high dynamic range scene performance. It is
programmable through a simple two-wire serial inter-
face. The AR0237 produces extraordinarily clear, sharp
digital pictures, and its ability to capture both continu-
ous video and single frames makes it the perfect choice
for a wide range of applications, including surveillance
and HD video.

AR0237CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
General Description
General Description
The ON Semiconductor AR0237 can be operated in its default mode or programmed for
frame size, exposure, gain, and other parameters. The default mode output is a 1080p-
resolution image at 60 frames per second (fps) through the HiSPi port. In linear mode, it
outputs 12-bit or 10-bit A-Law compressed raw data, using either the parallel or serial
(HiSPi) output ports. In high dynamic range mode, it outputs two exposure values that
the ISP will combine into an HDR image. The device may be operated in video (master)
mode or in single frame trigger mode.
FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a
synchronized pixel clock in parallel mode.
The AR0237 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
the first and last 2 lines of the image frame.
The AR0237 is designed to operate over a wide temperature range of -30°C to +85°C
ambient.

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 serial interface output pads and VDDSLVS can be left unconnected if the parallel output inter-
face 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. Refer to the AR0237 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.
7. The EXTCLK input is limited to 6-48 MHz.
