Product Description

AT7456E is a single-channel, monochrome on-screen display (OSD) generator with integrated EEPROM. It integrates a video driver, sync separator, video switch, and EEPROM, which improves system integration and effectively reduces system cost.

The AT7456E features 512 user-programmable characters compliant with NTSC and PAL standards, making it suitable for global markets.

The AT7456E can conveniently display various information—such as company logos, commonly used graphics, time, date, and more—using any characters and sizes.

The AT7456E comes pre-loaded with 512 characters and graphics and supports in-circuit programming via a SPI-compatible serial interface.

The AT7456E is available in a 28-pin HTSSOP package and a 16-pin LGA package, with an operating temperature range of -40°C to +85°C.
