MB90099

DESCRIPTION

■

The MB90099 is an on-screen display controller for displaying text and graphics on the TV screen. The three­channel output control function, compact package and low vo ltage operation make this device suitable for on­screen displays in portable devices including camera-integrated VTRs and digital still cameras.

DS04-28828-3E

The MB90099 controls a display area of 28 characters b y 12 lines, and provides 1,024 diff erent char acters, each
composed of 12 × 18 dots. All 1,024 characters in font R OM can be set b y the user . The displa y functions include
a wealth of characters with qualifying functions such as character background shading (shadow casting) and
individual character size setting, with 16-color display selection for each character. Also included are the line
background, screen background, and sprite character functions, pro viding a wide v ariety of screen displa y capa­bilities.

Receives serial commands and data. Decodes commands, and allocates commands and data to the appro­priate control blocks.

• Display control block
Performs display control functions synchronized with the input sync signals.

• Display memory (VRAM) block
VRAM memory for character data (24 bits × 28 characters × 12 lines) and line data (24 bits × 12 lines) .

•Font ROM block
ROM memory for display character fonts. Configured for 1,024 characters of 12 dots × 18 dots.

• Output control block
Generates output signals by applying display processing to the font data read from the font ROM.

• Test control block

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the

semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.

Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.

No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
