Product Specification
The GTX312L is one of the GreenTouch3LPTM capacitive touch sensor series. Especially the GTX312L can do capacitance sensing with 12 channels under above GreenTouch3LPTM engine operation. Thanks to the GreenTouch3LPTM low power engine, a variety of battery powered applications can increase product usage time. Also based on the technology of the existing GreenTouch3TM engine, reliability can be secured against various noise and environmental changes.
The internal control registers are readable and writable using I2C interface.The GTX312L can be applied under wide supply voltage range from 1.8V to 5.5V. The CTRL pin of the GTX312L provides switchable chip ID that make a couple of chip parallel operations on the same I2C bus.
