General Description
NT6827 is designed for displaying symbols and characters onto a CRT monitor. Its operation is controlled by a microcontroller with an I2C bus interface. By sending proper data and commands to NT6827, it can carry out the full screen display automatically with the time base being generated by an on-chip PLL circuit. There are many functions provided by this chip to fully support the user applications, such as: adjustment of the OSD windows position, built-in 256 ROM & 16 Multi-color fonts, variable character height with row-to-row spacing adjustment, 8 color selections & 7 background color controls for each character, double height/width controls for each row, 4 overlapping windows available with color & size controls, size controls for each window shadowing, color selection for windows' shadowing & characters' shadowing/ bordering and fade-in/out display effect ,etc.
