Tiny touch controller offers key functions

Ideal for use as a multimedia HMI controller in mobile phones and consumer applications, the AT42QT2160 touch controller IC combining touch key and touch slider functions in a single device can control up to 16 individual touch keys with a slider comprising between two and eight of the touch-key channels. In addition, the chip can also control up to 11 LEDs through a PWM output function that is controlled by the host, eliminating the need for an external LED controller.

The chip has three GPIOs with PWM capability and a further eight shared ports that provide additional standard GPIOs for the host without adding cost or using an extra I/O expansion device with PWM capability. Housed in a 28-pin package, the chip includes a voltage range from 1.8 to 5.5 Vdc, an I2 C interface, and a system multi-input wake-up function that can trigger a reaction from the host or other system components via I2C, or using a dedicated output pin, when pre-defined input signals levels are reached. (From $0.98 ea/10,000 available now.)
