LT776 is high performance Uart TFT Controller IC. Integrated with Cortex M4 32bit MCU core architecture and 2D graphic engine, LT776 can be controlled by the host MCU through Uart interface, and deliver complex contents onto the LCD panel through simple commands. In addition to its high-performance M4 MCU, LT776 also provides graphics processing and acceleration functions.

LT776 can improve the efficiency of displaying pictures/contents to the TFT panel and reduce the time it takes for the host MCU to process for the graphic display. LT776 supports 16bits RGB panels and MCU panels with 8/16bits interface. The maximum display resolution is 1024x768. LT776 has an embedded M4 core MCU, with a maximum speed of 500MHz, and contains 256Kbytes Flash, 192Kbytes SRAM. A QSPI Flash interface is available for accessing external SPI Flash to retrieve pictures, animation, and fonts etc. With the editing software and simulation tool provided by Levetop, users can easily get their project done with TFT display functions in no time. LT776 provides more than 80 commands, including picture display, GIF animation display, picture loop display, boot screen, progress bar, text string, QR code, audio playback, and touch touch function, etc. In addition, the built-in 128Mb display memory make multi-layer display possible with maximum resolution of 1024x768. Along with the Uart interface for comunicating with the host MCU, LT776 also provides multiple groups of SCI (Uart) interfaces that can connect to peripherals such as blue tooth modules and WiFi modules, etc. USB interfaces, SDIO, I2C, analog input AIN, DAC output, PWM and INT interrupts are also available. These interfaces can be set up as normal IO interfaces, too. A DCMI (Digital Camera Interface) is also available for connecting to a camera.

Benefiting from its high-capacity Flash and SRAM, LT776 can also be used as a host MCU with TFT controller.  LT776's powerful display capabilities are ideal for electronic products with TFT-LCD screens, such as smart home appliances, automotive dashboards, motorcycle panels, multifunction transaction machines, industrial control applications, electronic instruments, medical beauty equipment, testing equipment, charging equipment, hydropower meters, and smart audio player with TFT panel etc.
