General Description:

LT7681, LT7683+ and LT7686 are a series of high efficiency LCD Graphics Acceleration Display Controllers. The display resolution they support can be from 320*240 (QVGA)to 1280*1024(SVGA) while the display screen can support 16/18/24-bits RGB interface.

LTLT768x support various MCU interfaces, including SPI、I2C serial port interface and 8/16-bit MCU parallel port interface. In order to achieve multi-level, high resolution display effect,LT768x have 128Mb built-in display memory to support 1bit/pixel to 24bit(16M)/pixel color display. They also own built-in geometric drawing engine to provide functions like point drawing, line drawing, curve drawing, ellipse, triangle, rectangle, rounded rectangle drawing and so on. In addition, the chips have embedded hardware graphics processing unit to provide mandatory graphical operations like magic
rotation, flip, reflect, PIP(picture in picture) , hybrid graphics and transparent display, which greatly improve the display efficiency of the products and therefore extensively reduce the running burden of MCU softwares. If using high-speed SPI interface can reduce the need for MCU I/O port, and then there is no need to upgrade MCU for TFT screen. The powerful performance of LT768x are suitable for embedded systems with TFT-LCD display, such as home appliances, industrial control, electronic instruments, medical equipment, man-machine interface, industrial equipment, testing equipment, charging pile, multi-functional transaction machine, elevator instruction and check-in gate instruction.
