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. applications ? desktop and notebook pcs ? lcd monitors ? consumer electronics ? appliances features ? six (6) capacitive touch sensor inputs - cap1106 ? five (5) capacitive touch sensor inputs - cap1105 ? programmable sensitivity ? automatic recalibration ? individual thresholds for each button ? proximity detection ? multiple button pattern detection ? calibrates for parasitic capacitance ? analog filtering for system noise sources ? press and hold feature for volume-like applications ? multiple communication interfaces ?smbus / i 2 c compliant interface (cap1106-1 only) ? smsc bc-link interface (cap1106-2 only) ? spi communications (cap1105 only) ? low power operation ? 5ua quiescent current in deep sleep ? 50ua quiescent current in standby (1 sensor input monitored) ? samples one or more channels in standby ? available in 10-pin 3mm x 3mm rohs compliant dfn package 1. smsc, the smsc logo and righttouch are registered trademarks and the righttouch logo is a trademark of standard microsystems corporation ("smsc"). cap1106 block diagram cap1105 block diagram smbus / bc-link protocol vdd gnd capacitive touch sensing algorithm cs1 cs2 cs3 cs4 cs5 smclk 1 / bc_clk 2 smdata 1 / bc_data 2 alert# 1 / bc_irq# 2 1 = cap1106-1 2 = cap1106-2 cs6 spi protocol spi_clk spi_mosi spi_miso capacitive touch sensing algorithm cs1 cs2 cs3 cs4 cs5 spi_cs# vdd gnd
