The LT776 is a Uart serial control chip designed for TFT LCD panels. The LT776 adopts a 32bit M4 core architecture, and its main function is to provide Uart serial communication, so that the host MCU can easily transfer the content to be displayed on the TFT screen to the LCD driver on the TFT screen through simple commands. The LT776's internal hardware and program provides graphics processing functions, which can improve the efficiency of TFT display and reduce the time for the MCU to process the graphic display. The LT776 supports a maximum display resolution of 1024*768, and can be used for 16-bit RGB-interfaced TFT panels, 8/16-bit MCU-interfaced TFT panels, or monochrome STN panels, and it has a camera and a CAN bus interface.
