Features
• QTouch® Sensor Channels
– Up to 8 keys
• Integrated Haptic Engine
– Haptic events may be triggered by touch detection or controlled by a host microcontroller over SPI Data Acquisition – QTouchADC key measurement/touch detection method – Configurable measurement timing and averaging – Spread spectrum charge transfer – Raw data from channel measurement can be read over the SPI interface GPIO Pins – 12 dedicated bi-directional GPIO pins, plus up to 4 additional pins (replacing keys) – Configurable as software PWM Drive, digital inputs or outputs Device setup – Device configuration may be stored in NVRAM Operation – Power-On reset and brown-out detection – Internal calibrated oscillator Key Outline Sizes – 6 mm x 6 mm or larger (panel thickness dependent); widely different sizes an
