Korea GreenChip Capacitive Touch Chip - GTX314L

Capacitive Touch Chip - GTX314L is GreenTouch 3LP^TMOne of the capacitive touch products in the sensor series. In particular, GTX314L can perform capacitance detection with 14 channels under GreenTouch 3LP^TMEngine running. Due to GreenTouch 3LP^TMLow-power engine, various battery-powered applications can increase product usage time. Also, based on the existing GreenTouch3TM engine technology, reliability can be guaranteed against various noises and environmental changes. Internal control registers can be accessed using the I2C read/write interface. GTX314L can be applied to a wide supply voltage range of 1.8V to 5.5V. The CTRL pin of GTX314L provides a switchable chip ID for parallel operation of two chips on the same I2C bus.
