LDS6100/6120 Touch Family PureTouch® Capacitance Touch IC Family with Integrated LED Drivers Data Sheet
The LDS6100/6120 family of capacitance touch controllers from Integrated Device Technoogy® is optimized for the implementation of touch-based input controls including sliders, scroll wheels and buttons. A low power programmable capacitance-to-digital converter (CDC) supports up to 20 sensor inputs, 10 of which may be configured as direct communication mode (DCM) outputs that emulate mechanical buttons, enabling streamlined communication of touch events without the need to query the serial interface bus.When configured for capacitive sensing, the touch inputs are directed through an integrated switch matrix to a sigma-delta CDC which senses changes in the external sensor array. When a change in capacitance occurs above the user defined threshold, a touch event is recognized and the host processor is notified via an interrupt pin or DCM output. On the LDS6120 products, a variety of built-in LED lighting effects may be automatically initiated by a touch event with no processor intervention required.On-chip calibration logic continuously monitors the environment and automatically adjusts touch sensitivity to insure robust performance. Proprietary noise-filtering algorithms may also be activated to prevent false sensor activation in noisy system environments. The LDS6100/6120 family is offered with SPI-compatible, I2C-compatible and SMBus-compatible interfaces, selectable in real-time using the I/F select pins. General-purpose input/output (GPIO) and interrupt outputs are also provided for additional communication with the host processor.
