The PCA8514 is a member of the PCA85XX CMOS family
and is an on-screen character display generator controlled
by a microcontroller via the on-chip fast I
or the on-chip High-speed 3-wire serial interface. It is
suitable for use in high-end TV or camcorder applications
and has also been designed for use in conventional
mid-end TV with advanced graphic features.
DESCRIPTION
