WT6018
Digital Monitor Controller
Ver. 1.41 Jul-31-1998
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.
