WT6148/WT6160 is a microcontroller for digital controlled monitor produced by Weltrend Semiconductor, Inc. It contains an 8-bit CPU, 48K /60K bytes ROM, 1056 bytes RAM, 14 PWMs, parallel I/Os, SYNC signal processor, timer, DDC1/2B interface, master/slave I2C interface, 6-bit A/D converter and watch-dog timer.

The WT8045 is a silicon monolithic circuit designed for synchronous signal processing and power saving detection of multi-sync display monitors, which can cope with many kinds of PC's and workstations. It can be applied to display monitors supporting standard IBM VGA, VESA super VGA and IBM 8514/A video modes. It can also be used in other high-end display monitors supporting non-standard video modes with user-defined horizontal/vertical frequency ranges. The WT8045 incorporates many functional circuits, including horizontal/vertical frequency discrimination, display mode selection, and synchronous pulse polarity and power saving detection, into this single chip IC. WT8045 is more convenient for you to shrink the PC board size and to reduce the material and labor cost with fewer components.

WT8043 is a synchronous signal discriminator designed by Weltrend Semiconductor, Inc. for multi-sync display monitors. It supports standard IBM VGA, VESA super VGA and IBM 8514/A video modes, as well as non-standard video modes. It can accept separate H&V Synchronous signals with any polarities and supports VESA VGA (640x480, 640x400, 640x350), VESA SVGA (800x600), European SVGA (800x600), VESA new SVGA (800x600), XGA (1024x768) and 1280x1024 resolutions. It also supports NEC (24K) mode, 3 VESA New 75Hz timing modes and Apple MAC II (35k) display modes.
