Single-Channel Monochrome On-Screen Display with Integrated EEPROM

The MAX7456 single-channel monochrome on-screen display (OSD) generator lowers system cost by eliminating the need for an external video driver, sync separator, video switch, and EEPROM. The MAX7456 serves all national and international markets with 256 user-programmable characters in NTSC and PAL standards. The MAX7456 easily displays information such as company logo, custom graphics, time, and date with arbitrary characters and sizes. The MAX7456 is preloaded with 256 characters and pictographs and can be reprogrammed in-circuit using the SPI™ port.

The MAX7456 is available in a 28-pin TSSOP package and is fully specified over the extended (-40°C to +85°C) temperature range.
