SINGLE-CHIP 16-BIT MICROCOMPUTER
1. DESCRIPTION
This microcomputer is a single-chip microcomputer that adopts a
high-performance silicon gate CMOS process, and is contained in
a 100-pin plastic mold QFP. This single-chip microcomputer is provided with an instruction queue buffer and a data buffer for
executing instructions at high speed. The central processing unit
runs in a 16-bit parallel processing mode but can be converted
into an 8-bit parallel processing mode when necessary. This product has been designed exclusively for video equipment system
controls, incorporating a time measuring circuit for VCR servo
control, a real-time pattern generating circuit, analog amplifiers, an
OSD display circuit, and a data slicer, among its many other peripheral capabilities.
