The RX Family supports TFT display LCD controller, 2D drawing engine (graphic accelerator), image capture unit, and capacitive touch key functions, which are key technologies for human-machine interfaces (HMI). Self-capacitive touch, for highly sensitive proximity sensing, and water-resistant mutual-capacitive touch are built into a single chip. Functions for capturing images from a CMOS camera and the LCD controller for outputting those images are also built into a single chip, too.
