FEATURES

GENERAL DESCRIPTION

MTV048 is designed for monitor applications to display built-in fonts onto monitor screens. The display operation

occurs by transferring data and controls information from the micro controller to RAM through a serial data

interface. It can execute a full-screen display automatically, as well as specific functions such as character

background, bordering, shadowing, blinking, double height and width, font-by-font color control, button boxes,

frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-

screen erasing, fade-in/fade-out effect, windowing effect, shadowing on window and full-screen self-test pattern

generator.

MTV048 provides 384 fonts including 360 standard fonts, 16 multi-color fonts and 8 user fonts and 2 font sizes,

12x16 or 12x18 for more efficacious applications. The full OSD menu is formed by 15 rows x 30 columns, which

can be positioned anywhere on the monitor screen by changing vertical or horizontal delay.
