HMS9xC7132 / HMS9xC7134
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 I
2
C bus interface for control of the video and deflection functions of the
monitor.
