PAS6180 outputs yuv/ycrcb 4:2:2 or rgb565/555/444 data through the serial data bus. it is available in csp-16l package. the PAS6180 can be programmed to set the exposure time for different luminance condition via i2c tm serial control bus. by programming the internal register set, it performs on-chip frame rate adjustment, offset correction dac and programmable gain control. key specification resolution 240 (h) x 320 (v) pixel size 3.15um * 3.15um array diagonal 1/13? lens lens chief ray angle 23 degree color filter rgb bayer pattern power 2.8v typical input clock 52mhz output clock 52mhz max. frame rate 30fps scan mode progressive exposure time ~ frame time to line time sensitivity 1500mv/lux-sec s/n ratio 41db dynamic range 60db features ? resolution: 240 x 320 pixels, 1/13? lens ? bayer-rgb color filter array ? output format: z yuv/ycrcb 4:2:2 z rgb565/555/444 ? i2c tm interface ? power dissipation: operating typical tbd @ 2.8v (qvga yuv 30fps output, without loading), power-down typical tbd @ 2.8v ? automatic background compensation ? dsp function: z aec & agc z aw b z gamma z color matrix z sharpness z de-noise z color saturation z defect compensation z lens shading compensation z decimation and scaler ? woi & sub-sampling ? module size : 5.0mm * 5.0mm package csp-16l

( please refer to PAS6180 register description ) during write cycle, the master generate s start condition and then places the 1 st byte data that are combined slave address ( 7 bits ) with a read / write control bit to sda line. after slave ( PAS6180 ) issues acknowledgment, the master places 2 nd byte ( sub address ) data on sda line. again follow the PAS6180 acknowledgment, the master places the 8 bits data on sda line and transmit to PAS6180 control register ( address was assigned by 2 nd byte ). after PAS6180 issues acknowledgment, the master can generate a stop condition to end of this write cy cle. in the condition of multi-byte write, the PAS6180 sub-address is automatically incremen t after each data byte transferred. the data and a cycles is repeat until last byte write. every control registers value in side PAS6180 can be programming via this way. slave transmits data to master ( read cycle ) z the sub-address was taken from previous write cycle. z the sub-address is automatically increment after each byte read. z am : acknowledge by master. z note there is no acknowledgment fr om master after last byte read. during read cycle, the master genera tes start condition and then place the 1 st byte data that are combined slave address ( 7 bits ) with a read / write control bit to sda line. after issue acknowledgment, 8 bits data was also placed on sda line by PAS6180. the 8 bits data was read from PAS6180 internal control register that address was assigned by previous wr ite cycle. follow the master acknowledgment, the PAS6180 place the next 8 bits data ( address is incr ement automatically ) on sda line and then transmit to master serially. the data and am cycles is repeat until the last byte read. after last byte read, am is no longer generated by master but instead by keep sda line high. the slave ( PAS6180 ) must releases sda line to master to generate stop condition.
