Preliminary W78E378/W78C378/W78C374  
MONITOR CONTROLLER  
GENERAL DESCRIPTION  
The W78E378, W78C378 and W78C374B are ASIC which is a stand-alone high-performance  
microcontroller specially designed for monitor control applications. The device integrates the  
embedded 80C31 microcontroller core, on-chip MTP or Mask ROM, 576 bytes of RAM, and a number  
of dedicated hardware monitor functions. Additional special function registers are incorporated to  
control the on-chip peripheral hardware. The chip is used to control the interface signal of other  
devices in the monitor and to process the video sync signals. Because of the highly integration and  
Flash cell for program memory, the device can offer users the competitive advantages of low cost  
and reduced development time.
