ATMEL AT42QT2160-MMU 电容式触摸传感器, I2C, 1.8 V, 5.5 V, QFN, 28 引脚, -40 °C
The is a QMatrix Touch Sensor IC designed for use with up to 16 keys and a slider constructed from 2 keys up to 8 keys. The device is a digital burst mode charge-transfer QT™ sensor designed specifically for matrix layout touch controls; it includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. The device uses an I²C-compatible interface to allow key data to be extracted and to permit individual key parameter setup. The command structure is designed to minimize the amount of data traffic while maximizing the amount of information conveyed.
