LT7680 is a high peformance TFT LCD graphics controller ICs. It supports 16/18bits RGB panels with various resolutions ranging from 320x240 (QVGA) to 1280x1024 (SVGA). This chip is in QFN-68 package. Two models are available for users to choose from, based on the required resolution.
LT7680 supports SPI interface to communicate with the host MCU. In order to achieve multi-layers high resolution display effect, LT7680 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, LT7680 supports drawing points, lines, curves, ellipse, triangle, rectangle, rounded rectangle, and other functions. In addition, LT7680 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 LT7680 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 stations, multi-function machines, elevator, check-in gate, etc.
