AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
General Description
General Description
The ON Semiconductor AR023Z can be operated in its default mode or programmed for
frame size, exposure, gain, and other parameters. The default mode output is a 1080presolution 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 12-bit compressed data
using parallel output. In HiSPi mode, 12- or 14-bit compressed, or 16-bit linearized data
may be output. 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 AR023Z 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 AR023Z is designed to operate over a wide temperature range of -30°C to +85°C
ambient.

AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Functional Overview
Functional Overview
The AR023Z 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 48 MHz. The maximum output pixel rate is 148.5 Mp/s, corresponding to a clock
rate of 74.25 MHz. Figure 1 shows a block diagram of the sensor configured in linear
mode, and in HDR mode.

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 2.1 Mp 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 analogto-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

produce a single image at 16-bit per pixel value. A compression mode is further offered
to allow the 16 bits per pixel to be transmitted to the host system as a 12-bit value with
close to zero loss in image quality.

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 0.1F and 10F decoupling capacitors for each power supply
are mounted as close as possible to the pad. Actual values and results may vary depending on layout and design considerations. Refer to the AR023Z demo headboard schematics for circuit recommendations.
5. ON Semiconductor recommends that analog power planes are placed in a manner such that coupling 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.

Pixel Array Structure
While the sensor's format is 1928 x1088, additional active columns and active rows are
included for use when horizontal or vertical mirrored readout is enabled, to allow
readout to start on the same pixel. The pixel adjustment is always performed for monochrome or color versions. The active area is surrounded with optically transparent
dummy pixels to improve image uniformity within the active area. Not all dummy pixels
or barrier pixels can be read out.

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 (10, 14).
When the sensor is imaging, the active surface of the sensor faces the scene as shown in
Figure 7. 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 7.

AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Features Overview
Features Overview
For a complete description, recommendations, and usage guidelines for product
features, refer to the AR023Z Developer Guide.
3.0m Dual Conversion Gain Pixel
To improve the low light performance and keep the high dynamic range, a large (3.0um)
dual conversion gain pixel is implemented for better image optimization. With a dual
conversion gain pixel, the conversion gain of the pixel may be dynamically changed to
better adapt the pixel response based on dynamic range of the scene. This gain can be
switched manually or automatically by an auto exposure control module.
HDR
By default, the sensor powers up in HDR Mode. The HDR scheme used is multi-exposure
HDR. This allows the sensor to handle up to 105 dB of dynamic range. In HDR mode, the
sensor sequentially captures two exposures by maintaining two separate read and reset
pointers that are interleaved within the rolling shutter readout. The intermediate pixel
values are stored in line buffers while waiting for the two exposure values to be present.
As soon as a pixel's two exposure values are available, they are combined to create a
linearized 16-bit value for each pixel's response. The exposure ratio may be set to 4x, 8x,
16x, or 32x. Depending on whether HiSPi or Parallel mode is selected, the full 16 bit value
may be output, it can be compressed to 12 bits using Adaptive Local Tone Mapping
(ALTM), or companded to 12 or 14 bits.
Options to output T1 only, T2 only, or pixel interleaved data are also available. Individual
exposures may be read out in a line interleaved mode as described in the T1/T2 Line
Interleaved Mode section.
Resolution
The active array supports a maximum of 1928x1088 pixels to support 1080p resolution.
Utilizing a 3.0um pixel will result in an optical format of 1/2.7-inch (approximately
6.6mm diagonal).
Frame Rate
At full (1080p) resolution, the AR023Z is capable of running up to 3060 fps.
Image Acquisition Mode
The AR023Z supports two image acquisition modes:
• Electronic rolling shutter (ERS) mode
This is the normal mode of operation. When the AR023Z is streaming, it generates
frames at a fixed rate, and each frame is integrated (exposed) using the ERS. When ERS
mode is in use, timing and control logic within the sensor sequences through the rows of
the array, resetting and then reading each row in turn. In the time interval between resetting a row and subsequently reading that row, the pixels in the row integrate incident
light. The integration (exposure) time is controlled by varying the time between row
reset and row readout. For each row in a frame, the time between row reset and row
readout is the same, leading to a uniform integration time across the frame. When the
integration time is changed (by using the two-wire serial interface to change register
settings), the timing and control logic controls the transition from old to new integration

Features Overview
time in such a way that the stream of output frames from the AR023Z switches cleanly
from the old integration time to the new while only generating frames with uniform integration. See “Changes to Integration Time” in the AR023Z Register Reference.
• Global reset mode.
This mode can be used to acquire a single image at the current resolution. In this mode,
the end point of the pixel integration time is controlled by an external electromechanical
shutter, and the AR023Z provides control signals to interface to that shutter. The benefit
of using an external electromechanical shutter is that it eliminates the visual artifacts
associated with ERS operation. Visual artifacts arise in ERS operation, particularly at low
frame rates, because an ERS image effectively integrates each row of the pixel array at a
different point in time.
Embedded Data and Statistics
The AR023Z has the capability to output image data and statistics embedded within the
frame timing. There are two types of information embedded within the frame readout.
• Embedded Data:
If enabled, these are displayed on the two rows immediately before the first active
pixel row is displayed.
• Embedded Statistics:
If enabled, these are displayed on the two rows immediately after the last active pixel
row is displayed.
Multi-Camera Synchronization
The AR023Z supports advanced line synchronization controls for multi-camera (stereo)
support.
Slave Mode
The slave mode feature of the AR023Z supports triggering the start of a frame readout
from an input signal that is supplied from an external ASIC. The slave mode signal allows
for precise control of frame rate and register change updates.
Context Switching and Register Updates
The user has the option of using the highly configurable context memory, or a simplified
implementation in which only a subset of registers is available for switching. The
AR023Z supports a highly configurable context switching RAM of size 256 x 16. Within
this Context Memory, changes to any register may be stored. The register set for each
context must be the same, but the number of contexts and registers per context are
limited only by the size of the context memory.
Alternatively, the user may switch between two predefined register sets A and B by
writing to a context switch change bit. When the context switch is configured to context
A the sensor will reference the context A registers. If the context switch is changed from A
to B during the readout of frame n, the sensor will then reference the context B
coarse_integration_time registers in frame n+1 and all other context B registers at the
beginning of reading frame n+2. The sensor will show the same behavior when changing
from context B to context A. The registers listed in Table 4 are context-switchable:

Motion Compensation/DLO
In typical multi-exposure HDR systems, motion artifacts can be created when objects
move during the T1 or T2 integration time. When this happens, edge artifacts can potentially be visible and might look like a ghosting effect. To correct this, the AR023Z has
special 2D motion compensation circuitry that detects motion artifacts and corrects the
image. The motion compensation feature can be optionally enabled by register write.
Additional parameters are available to control the extent of motion detection and
correction as per the requirements of the specific application.
Tone Mapping
Real-world scenes often have a very high dynamic range (HDR) that far exceeds the electrical dynamic range of the imager. Dynamic range is defined as the luminance ratio
between the brightest and the darkest objects in a scene. Even though the AR023Z can
capture full dynamic range images, the images are still limited by the low dynamic range
of display devices. Today's typical LCD monitor has a contrast ratio around 1,000:1 while
it is not atypical for an HDR image having a contrast ratio of around 250,000:1. Therefore, in order to reproduce HDR images on a low dynamic range display device, the
captured high dynamic range must be compressed to the available range of the display
device. This is commonly called tone mapping. The AR023Z has implemented an adaptive local tone mapping (ALTM) feature to reproduce visually appealing images that
increase the local contrast and the visibility of the images.

AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Features Overview
Adaptive Color Difference (ADACD) Noise Filtering
A good noise reduction filter will remove noise from an image while retaining as much
image detail as possible. To retain image detail, the noise reduction filter must adapt to
the image signal. To remove noise, the noise reduction filter must adapt to the noise level
of the image signal. The key is to remove the appropriate amount of noise. Over-filtering
will cause image blurring while under-filtering will leave noise in the image. The AdaCD
algorithm relies on a noise model derived from characterization data to aid in separating
noise from signal.
The AR023Z AdaCD algorithm performs pixel-by-pixel color noise correction for each of
the red, blue, and green color planes. Each pixel is corrected based on surrounding pixel
values on the same color plane and a noise model. The noise model is based on characterization data, and takes into account applied analog gain.
Fast Mode Switch (Combi Mode)
To facilitate faster switching between linear and HDR modes, the AR023Z includes a
Combi Mode feature. When enabled, Combi Mode loads a single (HDR) sequencer.
When switching from HDR to linear modes, the sequencer remains the same, but only
the T1 image is output. While not optimized for linear mode operation, it allows faster
mode switching as a new sequencer load is not needed. Switching between modes may
result in the output of one bad frame.
Analog/Digital Gains
A programmable analog gain of 1.5x to 12x (HDR) and 1.5x to 16x (linear) applied simultaneously to all color channels will be featured along with a digital gain of 1x to 16x that
may be configured on a per color channel basis.
Skipping/Binning Modes
The AR023Z supports subsampling. Subsampling allows the sensor to read out a smaller
set of active pixels by either skipping, binning, or summing pixels within the readout
window. Horizontal binning is achieved in the digital readout. The sensor will sample
the combined 2x adjacent pixels within the same color plane. Vertical row binning is
applied in the pixel readout. Row binning can be configured as 2x rows within the same
color plane. Pixel skipping can be configured up to 2x in both the x-direction and ydirection. Skipping pixels in the x-direction will not reduce the row time. Skipping pixels
in the y direction will reduce the number of rows from the sensor effectively reducing the
frame time. Skipping will introduce image artifacts from aliasing.
The AR023Z supports row wise vertical binning. Row wise vertical summing is not
supported.
Clocking Options
The sensor contains a phase-locked loop (PLL) that is used for timing generation and
control. The required VCO clock frequency is attained through the use of a pre-PLL clock
divider followed by a multiplier. The PLL multiplier should be an even integer. If an odd
integer (M) is programmed, the PLL will default to the lower (M-1) value to maintain an
even multiplier value. The multiplier is followed by a set of dividers used to generate the
output clocks required for the sensor array, the pixel analog and digital readout paths,
and the output parallel and serial interfaces. Use of the PLL is required when using the
HiSPi interface.

AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Features Overview
Temperature Sensor
The AR023Z sensor has a built-in PTAT-based temperature sensor, accessible through
registers, that is capable of measuring die junction temperature. The value read out from
the temperature sensor register is an ADC output value that needs to be converted
downstream to a final temperature value in degrees Celsius. Since the PTAT device characteristic response is quite linear in the temperature range of operation required, a
simple linear function can be used to convert the ADC output value to the final temperature in degrees Celsius.
A single reference point will be made available via register read as well as a slope for
back-calculating the junction temperature value. An error of +/-5% or better over the full
specified operating range of the sensor is to be expected.
Silicon / Firmware / Sequencer Revision Information
A revision register will be provided to read out (via I2C) silicon and sequencer/OTPM
revision information. This will be helpful to distinguish among different lots of material
if there are future OTPM or sequencer revisions.
Lens Shading Correction
The latest lens shading correction algorithm will be included for potential low Z height
applications.
Companding
The 16-bit linearized HDR image may be compressed to 12- or 14- bits using on-chip
companding. This is useful if on-chip ALTM will not be used and the ISP cannot handle
16 bit data.
Compression
When the AR023Z is configured for linear mode operation, the sensor can optionally
compress 12-bit data to 10-bit using A-law compression. The A-law compression is
disabled by default.
Packaging
The AR023Z will be offered in a 10x10 80-iBGA package (parallel and HiSPi). The
package will have anti-reflective coating on both sides of the cover glass.
Parallel Interface
The parallel pixel data interface uses these output-only signals:
• FRAME_VALID
• LINE_VALID
• PIXCLK
• DOUT[11:0]
The parallel pixel data interface is disabled by default at power up and after reset. It can
be enabled by programming R0x301A. When the parallel pixel data interface is in use,
the serial data output signals can be left unconnected.

AR023Z: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor
Features Overview
High Speed Serial Pixel (HiSPi) Interface
The HiSPi interface supports three protocols, Streaming-S, Streaming-SP, and Packetized
SP. The streaming protocols conform to a standard video application where each line of
active or intra-frame blanking provided by the sensor is transmitted at the same length.
The Packetized SP protocol will transmit only the active data ignoring line-to-line and
frame-to-frame blanking data.
The HiSPi interface building block is a unidirectional differential serial interface with
four data and one double data rate (DDR) clock lanes. One clock for every four serial
data lanes is provided for phase alignment across multiple lanes. The AR023Z supports
serial data widths of 10, 12, 14, 16, or 20 bits on one, two, or four lanes. The specification
includes a DLL to compensate for differences in group delay for each data lane. The DLL
is connected to the clock lane and each data lane, which acts as a control master for the
output delay buffers. Once the DLL has gained phase lock, each lane can be delayed in
1/8 unit interval (UI) steps. This additional delay allows the user to increase the setup or
hold time at the receiver circuits and can be used to compensate for skew introduced in
PCB design. Delay compensation may be set for clock and/or data lines in the
hispi_timing register R0x31C0. If the DLL timing adjustment is not required, the data
and clock lane delay settings should be set to a default code of 0x0000 to reduce jitter,
skew, and power dissipation.
Sensor Control Interface
The two-wire serial interface bus enables read/write access to control and status registers within the AR023Z. The interface protocol uses a master/slave model in which a
master controls one or more slave devices. The sensor acts as a slave device. The master
generates a clock (SCLK) that is an input to the sensor and is used to synchronize transfers.
Data is transferred between the master and the slave on a bidirectional signal (SDATA).
SDATA is pulled up to VDD_IO off-chip by a 1.5k resistor. Either the slave or master
device can drive SDATA LOW-the interface protocol determines which device is allowed
to drive SDATA at any given time. The two-wire serial interface can run at 100 kHz or 400
kHz.
T1/T2 Line Interleaved Mode
The AR023Z has the capability to output the T1 and T2 exposures separately, in a line
interleaved format. The purpose of this is to enable off chip HDR linear combination
and processing. See the AR023Z Developer Guide for more information.

HiSPi Electrical Specifications
The ON Semiconductor AR023Z sensor supports both SLVS and HiVCM HiSPi modes.
Refer to the High-Speed Serial Pixel (HiSPi) Interface Physical Layer Specification
v2.00.00 for electrical definitions, specifications, and timing information. The VDD_SLVS
supply in this datasheet corresponds to VDD_TX in the HiSPi Physical Layer Specification. Similarly, VDD is equivalent to VDD_HiSPi as referenced in the specification. The
DLL as implemented on AR023Z is limited in the number of available delay steps and
differs from the HiSPi specification as described in this section.

3. After 100s, turn on VDD_IO power supply.
4. After 100s, turn on VDD power supply.
5. After 100s, turn on VDD_SLVS power supply.
6. After the last power supply is stable, enable EXTCLK.
7. Assert RESET_BAR for at least 1ms. The parallel interface will be tri-stated during this
time.
8. Wait 150000 EXTCLKs (for internal initialization into software standby.
9. Configure PLL, output, and image settings to desired values.
10. Wait 1ms for the PLL to lock.
11. Set streaming mode (R0x301a[2] = 1).

1. Xtal settling time is component-dependent, usually taking about 10 – 100 ms.
2. Hard reset time is the minimum time required after power rails are settled. In a circuit where Hard
reset is held down by RC circuit, then the RC time must include the all power rail settle time and
Xtal settle time.
3. It is critical that VDD_PLL is not powered up after the other power supplies. It must be powered
before or at least at the same time as the others. If the case happens that VDD_PLL is powered after
other supplies then sensor may have functionality issues and will experience high current draw on
this supply.
