STV0676 application example
3.1
USB webcam
Figure 2 shows a block diagram of a basic webcam using the minimum of external components.
The camera is controlled entirely through PC drivers over USB.
Note:
If required a custom USB PID/VID can be configured by the use of an EEPROM, as detailed in
Section 2.3
3.2
Embedded camera
Figure 3 shows a block diagram of a camera intended for embedded applications, outputting JPEG,
YCrCb or RGB preview over an 8bit bus, the third party electronics would control the STV0676
using I2C.
