AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor General Description General Description The ON Semiconductor AR0230CS 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 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 AR0230CS 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 AR0230CS is designed to operate over a wide temperature range of -30°C to +85°C ambient. AR0230CS/D Rev. 9, 6/16 EN 4 ©Semiconductor Components Industries, LLC,2016. AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor Functional Overview Functional Overview The AR0230CS 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.

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 AR0230CS/D Rev. 9, 6/16 EN 5 ©Semiconductor Components Industries, LLC,2016.

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.

AR0230CS: 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 AR0230CS Developer Guide. 3.0m 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 96 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 AR0230CS is capable of running up to 3060 fps. Image Acquisition Mode The AR0230CS supports two image acquisition modes: • Electronic rolling shutter (ERS) mode This is the normal mode of operation. When the AR0230CS 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 AR0230CS/D Rev. 9, 6/16 EN 13 ©Semiconductor Components Industries, LLC,2016. AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor Features Overview time in such a way that the stream of output frames from the AR0230CS switches cleanly from the old integration time to the new while only generating frames with uniform integration. See “Changes to Integration Time” in the AR0230CS 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 AR0230CS 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 AR0230CS 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 AR0230CS supports advanced line synchronization controls for multi-camera (stereo) support. Slave Mode The slave mode feature of the AR0230CS 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 AR0230 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: AR0230CS/D Rev. 9, 6/16 EN 14 ©Semiconductor Components Industries, LLC,2016.

When this happens, edge artifacts can potentially be visible and might look like a ghosting effect. To correct this, the AR0230CS 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 AR0230CS 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 AR0230CS 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.

AR0230CS: 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 AR0230CS 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 AR0230CS 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 AR0230CS 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 y-direction. 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 AR0230CS 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. AR0230CS/D Rev. 9, 6/16 EN 16 ©Semiconductor Components Industries, LLC,2016. AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor Features Overview Temperature Sensor The AR0230CS 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 AR0230CS 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 AR0230CS 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.

AR0230CS: 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 AR0230CS 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 AR0230CS. 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 AR0230CS 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 AR0230CS Developer Guide for more information.

This will automatically be the case if the device does not stretch the LOW period of the SCLK signal. If such a device does stretch the LOW period of the SCLK signal, it must output the next data bit to the SDATA line tr max + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCLK line is released. 7.

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. 30 ©Semiconductor Components Industries, LLC,2016. AR0230CS: 1/2.7-Inch 2.1 Mp/Full HD Digital Image Sensor Power-On Reset and Standby Timing Power-Down Sequence The recommended power-down sequence for the AR0230CS is shown in Figure 12. The available power supplies (VDD_IO, VDD, VDD_SLVS, VDD_PLL, VAA, VAA_PIX) must have the separation specified below. 1. Disable streaming if output is active by setting standby R0x301a[2] = 0 2. The soft standby state is reached after the current row or frame, depending on configuration, has ended. 3. Turn off VDD_SLVS. 4. Turn off VDD. 5. Turn off VDD_IO. 6. Turn off VAA/VAA_PIX. 7. Turn off VDD_PLL.
