CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER

FOR MONITOR

1. OVERVIEW

1.1 Description

The HMS9xC7132/4 is a single-chip microcontroller of the 80C51 family, which is dedicated for monitor application. It is particularly

suitable for multi-sync computer monitor controller. This contains DDC interfaces to the PC host, sync-detector and sync-processor for

auto-sync application, ADC, static PWM, dynamic PWM and I2C bus interface for control of the video and deflection functions of the

monitor.
