s DESCRIPTION
The MB90097 is the on-screen display controller for displaying text and graphics on the TV screen. Since it has
a three-channel output control function, small package, and low voltage requirement for operation, it is suitable
for on-screen display on video equipment such as camera-integrated VTRs.
The MB90097 provides a display screen made up of 28 characters by 12 lines, capable of displaying 512 different
characters each consisting of 12 × 18 dots. The display functions of the MB90097 includes a wealth of character
qualifying functions such as character background shading (shadow casting) and individual character size setting,
supporting 16-color display for each character. They also include the line background, screen background, and
sprite character display functions, enabling the screen to be displayed in a variety of configurations. The integrated
font ROM contains 512 different character patterns all of which can be set by the user.
s FEATURES
• Character screen configuration: 28 characters × 12 lines (maximum)
• Character types: 512 different characters (integrated in ROM, user-definable through the entire area)
