The W78E354 is a stand-alone high-performance microcontroller ASIC specially designed for use in monitor control applications. Using the Winbond 0.8 DPDM process, the W78E354 integrates an embedded 8031 microcontroller core, 16K bytes of Flash cell, 512 bytes of RAM and a number of dedicated hardware functions. These hardware functions include a 6-bit A/D converter, two/fourteen 12/8-bit PWM static DACs, one/three 12/8-bit PWM dynamic DACs, a sync processor, one DDC port, a watchdog timer and other custom glue logic. Additional special function registers are incorporated to control the on-chip peripheral hardware. The chip is used to control the interface signals of other devices in the monitor and to process the video sync signals. Because of high integration and the incorporation of Flash cell for program memory, the device offers the user the competitive advantages of low cost and reduced development time. |
