LT768x is a high peformance TFT LCD graphics controller IC series. It supports 16/18/24bits RGB panels with various resolutions ranging from 320x240 (QVGA) to 1280x1024 (SVGA). All of these chips are in LQFP128 package.
LT768x supports a variety of MCU interface, including SPI, I2C serial port, and 8-bit/16-bit parallel interface. In order to achieve multi-layers high resolution display effect, it has a built-in 128Mb Display RAM, which can support assorted color depths from 1bit per pixel (2 gray shades) to 24bits per pixel (16M color), and alleviate the processing burden on MCU while displaying animation. With built-in geometric drawing engine, LT768x supports drawing points, lines, curves, ellipse, triangle, rectangle, rounded rectangle, and other functions. In addition, LT768x has an embedded hardware graphics acceleration engine (BTE), which provides command-type graphic operations such as screen rotation, flipping, mirroring, PIP and graphics blending, and transparent display. These functions can greatly enhance the display performance, and ease the processing burden on the MCU. Furthermore, users can use SPI interface to connect with MCU, and save the I/O ports of the MCU for other purposes. The powerful display performance of LT768x is ideal for embedded systems with TFT-LCD displays such as home appliances, industrial controls, electronic instruments, medical devices, human-machine interfaces, industrial equipment, inspection equipment, charging station, multi-function machines, elevator, check-in gate, etc.
