LDS6020
PureTouch Capacitance Touch IC with Integrated
Keypad LED Drivers
The LDS6020 PureTouch controller empowers 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 LDS6020 is a programmable capacitance-to-digital converter (CDC) designed for use with capacitive
sensor arrays implementing touch-based input controls including sliders, scroll wheels, and buttons.
Featuring 13 sensor inputs, 8 of which are dual-purpose I/Os configurable as either capacitive sensor
inputs or keypad LED drivers, the LDS6020 provides the flexibility to implement multiple touch inputs
with integrated lighting effects using a single controller.
When configured for capacitive sensing, the I/Os are directed through an integrated switch matrix to a
500 kHz sigma-delta CDC which senses changes in the external sensor array. When a sufficiently large
change in capacitance occurs, a sensor activation is registered and the host processor is notified. LED
lighting effects are automatically initiated by a touch event with no processor intervention required.
On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off
threshold levels to prevent false sensor activation. The LDS6020 is offered with both SPI-compatible
and I
2C-compatible interfaces (active interface selected by I/F select pin) and features a general-purpose
input/output (GPIO) and interrupt output for additional communication with the host processor.
