CXD3172AR
100 pin LQFP (Plastic)
Description
The CXD3172AR is a signal processor LSI for Ye,
Cy, Mg and G single CCD color cameras. In addition
to basic camera signal processing functions, it
includes an AE/AWB detection circuit, a sync signal
generation circuit and an external sync circuit, etc.
This chip also has a built-in microcontroller to realize
basic camera functions such as AE/AWB without an
external microcomputer.
