5 and 6 Channel Capacitive Touch Sensor

PRODUCT FEATURES

General Description

The CAP1106 and CAP1105, which incorporate SMSC’s

RightTouch

Touch sensors. The CAP1106 contains six (6) individual

capacitive touch sensor inputs while the CAP1105 contains

five (5) sensor inputs. Both devices offer programmable

sensitivity for use in touch sensor applications. Each sensor

input automatically recalibrates to compensate for gradual

environmental changes.

The CAP1105 / CAP1106 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 CAP1105 / CAP1106 includes circuitry and

support for enhanced sensor proximity detection.

The CAP1105 / CAP1106 offers multiple power states

operating at low quiescent currents. In the Standby state of

operation, one or more capacitive touch sensor inputs are

active.

Deep Sleep is the lowest power state available, drawing

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

active. Communications will wake the device.
