1 / 4 page  SMSC CAP1105 / CAP1106 Revision 1.32 (01-05-12) PRODUCT PREVIEW Data Brief PRODUCT FEATURES CAP1105 / CAP1106 5 and 6 Channel Capacitive Touch Sensor General Description The CAP1106 and CAP1105, which incorporate SMSC’s RightTouch® 1 technology, are multiple channel Capacitive 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.
