Description

ILITEK ILI9340 TFT LCD Driver unit

The ILITEK ILI9340 is a 240x320 Resolution RGB 262K color TFT LCD Single Chip Driver that supports color depths of 16 or 18bit. This driver supports the chip only in 16 bit depth using RGB565 format.

The chip provides an SPI interface at up to 32MHz and supports rotations of 0, 90, 180 and 270 degrees.
