MAX7456EUI

Product Summary

The MAX7456EUI is a single-channel monochrome on-screen display (OSD) generator. It lowers system cost by elimi- nating the need for an external video driver, sync separator, video switch, and EEPROM. The MAX7456EUI serves all national and international markets with 256 user-pro- grammable characters in NTSC and PAL standards. The MAX7456EUI+T easily displays information such as company logo, custom graphics, time, and date with arbitrary characters and sizes. The MAX7456EUI is preloaded with 256 characters and pictographs and can be reprogrammed in-circuit using the SPI port. The applications of the MAX7456EUI inlcude Security Switching Systems, Security Cameras, Industrial Applications, In-Cabin Entertainment, Consumer Electronics.
