industries, llc,2015. ar0330: 1/3-inch cmos digital image sensor general description general description the ar0330 can be operated in its default mode or programmed for frame size, expo- sure, gain, and other parameters. the default mode output is a 2304 x 1296 image at 60 frames per second (fps). the sensor output s 10- or 12-bit raw data, using either the parallel or serial (hispi, mipi) output ports. functional overview the ar0330 is a progressive-scan sensor that generates a stream of pixel data at a constant frame rate. it uses an on-chip, ph ase-locked loop (pll) that can generate all internal clocks from a sing le master input clock running between 6 and 27 mhz. the maximum output pixel rate is 196 mp/s using a 4-lane hispi or mipi serial interface and 98 mp/s using the parallel interface. figure 1 shows a block diagram of the sensor. figure 1: block diagram user interaction with the sensor is through the two-wire serial bus, which communi- cates with the array control, analog signal chai n, and digital signal chain. the core of the sensor is a 3.4mp active- pixe l sensor array. the timing an d 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 signal from the column is amplified in a column amplifier and then digitized in an analog-t o-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 provid es further data path corrections and applies digital gain).

on v dd power supply. 4. after 10 ?? s, turn on v dd _io power supply. 5. after the last power supply is stable, enable extclk. 6. assert reset_bar for at least 1ms. 7. wait 150,000 extclk periods (for internal initialization into software standby. 8. write r0x3152 = 0xa114 to configure the internal register initialization process. 9. write r0x304a = 0x0070 to start the inte rnal register initialization process. 10. wait 150,000 extclk periods 11. configure pll, output, and image settings to desired values. 12. wait 1ms for the pll to lock. 13. set streaming mode (r0x301a[2] = 1). figure 6: power up notes: 1. a software reset (r0x301a[0] = 1) is not nece ssary after the procedure described above since a hard reset will automatically triggers a software reset. in dependently executing a so ftware reset, should be followed by steps seven through thirteen above 2. the sensor must be receiving the external input cl ock (extclk) before the reset pin is toggled. the sensor will begin an internal initialization sequen ce when the reset pin toggle from low to high. this initialization sequence will run using the external input clock. power on default state is soft- ware standby state, need to apply two-wire seri al commands to start streaming. above power up sequence is a general power up sequence. for different interface configurations, mipi, and parallel, some power rails are not needed. those not needed power rails should be ignored in the general power up sequence. ar0330_ds rev. u pub. 4/15 en 16 ?semiconductor components industries, llc,2015. ar0330: 1/3-inch cmos digital image sensor sensor initialization notes: 1. external clock settling time is componen t-dependent, usually taking about 10 C 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 ti me must include the all power rail settle time and xtal settle time. 3. it is critical that v dd _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 v dd _pll is powered after other supplies then sensor may have functionality issues and will experience high current draw on this supply. 4. v dd _mipi is tied to v dd _pll in the both the clcc and csp packages and must be powered to 2.8 v. the v dd _hispi and v dd _hispi_tx supplies do not need to be tu rned on if the sensor is configured to use the mipi or parallel interface. table 7: power-up sequence definition symbol min typ

llc,2015. sensor readout image acquisition modes the ar0330 supports two image acquisition modes: ? electronic rolling shutter (ers) mode this is the normal mode of operation. wh en the ar0330 is streaming; it generates frames at a fixed rate, and each frame is integrated (exposed) using the ers. when the ers is in use, timing and control logic wi thin the sensor sequen ces 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 inci- dent 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 th e two-wire serial interface to change regis- ter settings), the timing and control logic co ntrols the transition from old to new inte- gration time in such a way that the stream of output frames from the ar0330 switches cleanly from the old integration time to the new while only generating frames with uniform integration. see ?changes to integration time? in the ar0330 register refer- ence. ? 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 ti me is controlled by an external electro- mechanical shutter, and the ar0330 provides control signals to interface to that shut- ter. the benefit of using an external electromech anical shutter is that it eliminates the visual artifacts associated with ers operatio n. 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. ar0330_ds rev. u pub. 4/15 en 47 ?semiconductor components industries, llc,2015. ar0330: 1/3-inch cmos digital image

en 49 ?semiconductor components industries, llc,2015. subsampling the ar0330 supports subsamplin g. subsampling allows the se nsor to read out a smaller set of active pixels by either skipping or binning pixels within the readout window. the working modes described in the data sheet th at use subsampling are configured to use either 2x2 or 3x3 subsampling. figure ? 33: ?? horizontal ? binning ? in ? the ? ar0330 ? sensor horizontal binning is achieved either in th e pixel readout or the digital readout. the sensor will sample the combined 2x or 3x adjacent pixels within the same color plane. figure ? 34: ?? vertical ? row ? binning ? in ? the ? ar0330 ? sensor vertical row binning is applied in the pixel re adout. row binning can be configured of 2x or 3x rows within the same color plane. on semiconductor recommends not to use 3x binning in ar0330 as it may introduce some image artifacts. pixel skipping can be configured up to 2x and 3x in both the x-direction and y-direction. skipping pixels in the x-direction will not re duce 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 sensor increments its x and y address based on the x_odd_inc and y_odd_inc value. the value indicates the addresses that are skipped after each pair of pixels or rows has been read. the sensor will increment x and y addresses in multiples of 2. this indicates that a greenr and red pixel pair will be read together . as well, that the sensor will read a gr-r row first followed by a b-gb row.

the sensor integration time is configured to be less than the frame period, then the sensor will not have reset all of the sensor rows before it begins waiting for the input vd signal. this error can

area will receive the value speci- fied by the selected test pattern and the dark pixels will receive the value in test_pat- tern_green (r0x3074 and r0x3078) for green pixels, test_pattern_blue (r0x3076) for blue pixels, and test_pattern_red (r0x3072) for red pixels. solid color when the color field mode is selected, the value for each pixel is determined by its color. green pixels will receive the value in test_pattern_green, red pixels will receive the value in test_pattern_red, and blue pixels will receive the value in test_pattern_blue. vertical color bars when the vertical color bars mode is select ed, a typical color bar pattern will be sent through the digital pipeline. table 40: a-law compression table for 12-10 bits input range input values compressed codeword 11 10 9 8 7

wa lking 1s pattern will be sent through the digital pipeline. the first value in each row is 1. two-wire serial register interface the two-wire serial interface bus enables read /write access to control and status regis- ters within the ar0330. this interface is de signed to be compatible with the electrical characteristics and transfer protocols of the i 2 c specification. 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 (s clk ) that is an input to the sensor and is used to synchronize transfers. data is transferred between the master and the slav e on a bidirectional signal (s data ). s data is pulled up to v dd _io off-chip by a 1.5k ? resistor. either the slave or master device can drive s data low?the interface protocol determines which device is allowed to drive s data at any given time. the protocols described in the two-wire seri al interface specific ation allow the slave device to drive s clk low; the ar0330 uses s clk as an input only and therefore never drives it low. protocol data transfers on the two-wire serial interf ace bus are performed by a sequence of low- level protocol elements: 1. a (repeated) start condition 2. a slave address/data direction byte 3. an (a no-) acknowledge bit 4. a message byte 5. a stop condition the bus is idle when both s clk and s data are high. control of the bus is initiated with a start condition, and the bus is released wi th a stop condition. only the master can generate the start and stop conditions. start condition a start condition is defined as a high-to-low transition on s data while s clk is high. at the end of a transfer, the master can generate a start condition without previously generating a stop cond ition; this is known as a ?repeated start? or ?restart? condition. stop condition a stop condition is defined as a low-to-high transition on s data while s clk is high. data transfer data is transferred serially, 8 bits at a time, with the msb transmitted first. each byte of data is followed by an acknowledge bit or a no-acknowledge bit. this data transfer mechanism is used for both the slave address/data direction byte and for message bytes. one data bit is transferred during each s clk clock period. s data can change when s clk is low and must be stable while s clk is high. ar0330_ds rev. u pub. 4/15 en 61 ?semiconductor components industries, llc,2015. ar0330: 1/3-inch cmos digital image sensor two-wire serial register interface slave address/data direction byte bits [7:1] of this byte represent the device slave address and bit [0] indicates the data transfer direction. a ?0? in bit [0] indicates a write, and a ?1? indicates a read. the default slave addresses used by the ar0330 sensor are 0x20 (write address) and 0x21 (read address). alternate slave addresses of 0x30 (write address) and 0x31 (read address) can be selected by asserting the s addr signal (tie high). alternate slave addresses can also be programmed through r0x31fc. message byte message bytes are used for sending register addresses and register write data to the slave device and for retrieving register read data. acknowledge bit each 8-bit data transfer is followed by an acknowledge bit or a no-acknowledge bit in the s clk clock period following the data transfer. the transmitter (which is the master when writing, or the slave when reading) releases s data . the receiver indicates an acknowl- edge bit by driving s data low. as for data transfers, s data can change when s clk is low and must be stable while s clk is high. no-acknowledge bit the no-acknowledge bit is generated when the receiver does not drive s data low during the sclk clock period following a data transfer. a no-acknowledge bit is used to terminate a read sequence. typical sequence a typical read or write sequence begins by the master generating a start condition on the bus. after the start condition, the master sends the 8-bit slave address/data direction byte. the last bit indicates whether the request is for a read or a write, where a ?0? indi- cates a write and a ?1? indicates a read. if the address matches the address of the slave device, the slave device acknowledges receipt of the address by generating an acknowl- edge bit on the bus. if the request was a write, the master then transfers the 16-bit register address to which the write should take place. this transfer takes place as two 8-bit sequences and the slave sends an acknowledge bit after each sequ ence to indicate that the byte has been received. the master then transfers the data as an 8-bit sequence; the slave sends an acknowledge bit at the end of the sequence . the master stops writing by generating a (re)start or stop condition. if the request was a read, the master sends the 8-bit write slave address/data direction byte and 16-bit register address, the same wa y as with a write request. the master then generates a (re)start condition and the 8-bit read slave address/data direction byte, and clocks out the register data, eight bits at a time. the master generates an acknowledge bit after each 8-bit transfer. the slave?s inte rnal register address is automatically incre- mented after every 8 bits are transferred. the data transfer is stopped when the master sends a no-acknowledge bit. ar0330_ds rev. u pub. 4/15 en 62 ?semiconductor components industries, llc,2015. ar0330: 1/3-inch cmos digital image sensor two-wire serial register interface single read from random location this sequence (figure 42) starts with a dummy write to the 16-bit address that is to be used for the read. the master terminates th e write by generating a restart condition. the master then sends the 8-bit read slave address/data direction byte and clocks out one byte of register data. the master termin ates the read by generating a no-acknowl- edge bit followed by a stop condition. figure 42 shows how the internal register address maintained by the ar0330 is loaded and incremented as the sequence proceeds. figure 42: single read from random location single read from current location this sequence (figure 43) performs a read using the current value of the ar0330 internal register address. the master terminates th e read by generating a no-acknowledge bit followed
