---

Small control panel processor for battery-driven consumer devices such as mobile phones, personal media players, PDAs, digital picture frames, and other mobile appliances. The device includes 16 touch channels, a slider using two to eight channels plus LED control, I/O expansion, and a two-wire serial interface compatible to the industry-standard I2C bus. Based on Atmel QMatrix™ and QSlide® technologies, it has very low power requirements and provides a very wide range of host-programmable input/output configurations.

Features:

• Number of keys: up to 16 keys, and one slider (constructed from 2 to 8 keys)
• Number of I/O lines: 11 (3 dedicated - configurable for input or output, 8 shared - output only), PWM control for LED driving
• Key outline sizes: 6 mm x 6 mm or larger (panel thickness dependent); widely different sizes and shapes possible
• Key spacings: 8 mm or wider, center to center (panel thickness dependent)
• Slider design: 2 to 8 keys placed in sequence, same design as keys
• Electrode design: two-part electrode shapes (drive-receive); wide variety of possible layouts
• PCB layers required: one layer (with jumpers), two layers (no jumpers)
• Interface: I2C-compatible slave mode (100kHz)
• Power: 1.8 V to 5.5 V
