Overview：

The AT7456E is a single-channel, monochrome on-screen display generator integrated with EEPROM. It integrates a video driver, a synchronization separator, a video separation switch and EEPROM, which enhances the system's integration and effectively reduces system costs. The AT7456E adopts 512 user-programmable characters that comply with the NTSC and PAL standards, making it suitable for the global market. The AT7456E can conveniently display various information in any character and size, such as company logos, common graphics, time, date, etc. The AT7456E is pre-loaded with 512 characters and graphics and can be programmed online via a SPI-compatible serial interface. The AT7456E is available in a 28-pin TSSOP package with an operating temperature range of -40 ° C to +85 ° C.
