Description
The M61250BFP is a single-chip semiconductor integrated circuit that contains the signal processing for NTSC color
television.
All of the signal processing circuits for video intermediate frequencies, vocal intermediate frequencies, video, color,
and polarization, as well as I²C bus control, are built in, and television sets ranging from popular-class to medium-grade
sets are supported. Moreover, the M37150 8-bit microcomputer for the television and the interconnection pin are
opposite each other, so that less space is required for mounting.
