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.
