5 MICROCONTROLLER (VCTP)
5.1 General Features
The VCT 7wxyP is dedicated to high-quality FPD and double-scan TV sets. Modular
design and deep-submicron technology allow the economic integration of features in
LCD/plasma TV and in all classes of double-scan CRT TV sets. The VCT 7wxyP family
is based on approved functional blocks of existing Micronas products for audio and
video.
Each member of the family contains the entire audio, video, up-conversion processing
for 4:3 and 16:9 50/60 Hz progressive or 100/120 Hz interlaced stereo TV sets and the
control/data interface for flat-panel displays. The integrated microcontroller is supported
by a powerful OSD and graphics generator with integrated teletext acquisition.
