6 Channel Capacitive Touch Sensor with 6 LED Drivers

PRODUCT FEATURES

General Description

The CAP1166, which incorporates SMSC’s RightTouch

technology, is a multiple channel Capacitive Touch sensor

with multiple power LED drivers. It contains six (6)

i n d i v i d u a l c a p a c i t i v e t o u c h s e n s o r i n p u t s w i t h

programmable sensitivity for use in touch sensor

applications. Each sensor input automatically recalibrates

to compensate for gradual environmental changes.

The CAP1166 also contains six (6) LED drivers that offer

full-on / off, variable rate blinking, dimness controls, and

breathing. Each of the LED drivers may be linked to one of

the sensor inputs to be actuated when a touch is detected.

As well, each LED driver may be individually controlled via

a host controller.

The CAP1166 includes Multiple Pattern Touch recognition

that allows the user to select a specific set of buttons to be

touched simultaneously. If this pattern is detected, then a

status bit is set and an interrupt generated.

Additionally, the CAP1166 includes circuitry and support for

enhanced sensor proximity detection.

The CAP1166 offers multiple power states operating at low

quiescent currents. In the Standby state of operation, one

or more capacitive touch sensor inputs are active and all

LEDs may be used. If a touch is detected, it will wake the

system using the WAKE/SPI_MOSI pin.

Deep Sleep is the lowest power state available, drawing

5uA (typical) of current. In this state, no sensor inputs are

active. Driving the WAKE/SPI_MOSI pin or communications

will wake the device.
