ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor
Architecture
System Block Diagram
The system block diagram will depend on the application. The system block diagram in
Figure 2 shows all components; optional peripheral components are highlighted.
Control information will be received by a microcontroller through the automotive bus to
communicate with the ASX340AT through its two-wire serial bus. Optional components
will vary by application.
