LDS6100/6120 Touch Family
PureTouch Capacitance Touch IC Family with Integrated LED Drivers
The IDT LDS6100/6120 family of PureTouch controllers empower system designers to create
streamlined, attractive and reliable product designs with capacitive touch controls. Integrated LED drivers
allow visual feedback to be implemented when a touch occurs, without the need for host intervention.
Description
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.
