CXD3141R fiche technique
CXD3141R
Signal Processor LSI for Single-Chip CCD Color Camera
Description
The CXD3141R is a signal processor LSI for Ye,
Cy, Mg and G single-chip 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.
80 pin LQFP (Plastic)
