WT6018 Datasheet Digital Monitor Controller

Manufacturer: Weltrend Semiconductor

Overview: WT6018 Digital Monitor Controller Ver. 1.41 Jul-31-1998 GENERAL.

General Description

The WT6018 is a member of WT60XX microcontroller family.

It is specially designed for digital controlled multi-sync monitor.

It contains 8-bit CPU, 8K bytes ROM, 288 bytes RAM, 14 PWMs, parallel I/O, SYNC processor, timer, DDC interface (slave mode I2C interface with DDC1), two 4-bit A/D convertors and watch-dog timer.

Key Features

  • 8-bit 6502 compatible CPU, 4MHz operating frequency.
  • 8192 bytes ROM, 288 bytes SRAM.
  • 8MHz crystal oscillator.
  • 14 channels 8-bit/62.5kHz PWM outputs (8 open drain outputs & 6 CMOS outputs).
  • Sync signal processor with H+V separation, frequency calculation, H/V polarity detection/control.
  • Three free-running sync signal outputs for burn-in test (64kHz/62.5Hz, 48kHz/75Hz, 31kHz/60Hz).
  • Self-test pattern generator generates cross hatch picture.
  • Provide half freq.
