The FT800 is a restive touch controller IC which provides a powerful feature set in a small package to create dynamic Human Machine Interfaces (HMIs).

The device supports line by line graphics rendering to 1/16 of a pixel on displays with resolution up to 512 x 512 with 262K colors.

The chip includes a touch controller for sensing touch feedback from a TFT display with a resistive touch panel as well as a sound synthesizer and audio playback with a PWM output to drive a speaker.
