Description
The VS6502 is a VGA resolution SmOP sensor
module. SmOP technology combines the
image sensor and fixed focus lens system in a
single module. The SmOP sensor module is
connected to the PCB either via a socket or flex
option. The socket allows the PCB to use
standard reflow soldering techniques.
The sensor outputs 10-bit raw digital image
data which directly interface to a range of
STMicroelectronics companion processors via
4/5 wire interface.
An I
2
C interface allows the processor to
configure the device and control exposure and
gain settings.
There are three different digital video output
formats:
VGA mode - 640 x 480 image size
Sub-sampled QVGA mode - 320 x 240
image size
Window Of Interest QVGA mode - 320 x 240
