Description
The W78C31BP-16 is an ASIC (Application-Specific Integrated Circuit) that is a stand-alone high-performance microcontroller specially designed for monitor control applications. It integrates the embedded 80C31 microcontroller core, on-chip MTP or Mask ROM, 576 bytes of RAM, and a number of dedicated hardware monitor functions. The chip is used to control the interface signal of other devices in the monitor and to process the video sync signals. With its highly integrated design and Flash cell for program memory, this microcontroller offers low cost and reduced development time.
