Description

The Himax HX8357D is a 320 x 480 RGB, 16M color TFT LCD Single Chip Driver that supports color depths of 16, 18 or 24bit. This driver supports the chip in both 16 and 24 bit depths using RGB888 or RGB565 formats.

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