PAS6337 Specification
PAS6337 CMOS VGA DIGITAL IMAGE SENSOR
General Description
The PAS6337 is a highly integrated CMOS active-pixel image sensor that has output of 640 x 480 pixels. It
embedded the new FinePixel™ sensor technology to perform the excellent image quality. PAS6337 outputs
YUV/YCrCb 4:2:2 or RGB565/555/444 data through the MIPI interface. It is available in CSP-22L package.
The PAS6337 can be programmed to set the exposure time for different luminance condition via I2CTM serial
control bus. By programming the internal register set, it performs on-chip frame rate adjustment and
programmable gain control.

Data Transfer Format
Master transmits data to salve ( write cycle )
z S : Start.
z A : Acknowledge by salve.
z P : Stop.
z RW : The LSB of 1ST byte to decide whether current cycle is read or write cycle. RW = 1 –
Read cycle, RW = 0 – Write cycle.
z SUBADDRESS : The address values of PAS6337 internal control registers. ( Please refer to
PAS6337 register description )
During write cycle, the master generates start condition and then places the 1st byte data that are
combined slave address ( 7 bits ) with a read / write control bit to SDA line. After slave ( PAS6337 )
issues acknowledgment, the master places 2nd byte ( Sub Address ) data on SDA line. Again follow the
PAS6337 acknowledgment, the master places the 8 bits data on SDA line and transmit to PAS6337
control register ( address was assigned by 2nd byte ). After PAS6337 issues acknowledgment, the master
can generate a stop condition to end of this write cycle. In the condition of multi-byte write, the PAS6337
sub-address is automatically increment after each DATA byte transferred. The data and A cycles is repeat
until last byte write. Every control registers value inside PAS6337 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 from master after last byte read.
During read cycle, the master generates start condition and then place the 1st 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 PAS6337. The 8 bits data was read from PAS6337 internal control
register that address was assigned by previous write cycle. Follow the master acknowledgment, the
PAS6337 place the next 8 bits data ( address is increment 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 ( PAS6337 ) must releases
SDA line to master to generate STOP condition.
