Description

The W78C354 is a high-performance monitor microcontroller that is based on the embedded 80C32 microcontroller core. The W78C354 includes a 16 KB ROM, 512 byte internal data RAM, a 6-bit A/D converter, two 12-bit and fourteen 8-bit PWM static DACs, one 12-bit and three 8-bit PWM dynamic DACs, a sync processor, an I2C port, a DDC port, a watchdog timer, and glue logic specially designed for monitor applications.

The W78C354 is suitable for monitors applying VESA DDC1/DDC2B/DDC2B+. This product's high level of integration and the availability of a one-time programmable (OTP) flash PROM version(the W78E354) help to reduce unit costs, development costs, and development time.
