1 / 102 page  SMSC CAP1114 DATASHEET Revision 1.1 (02-04-11) Datasheet PRODUCT FEATURES CAP1114 Multiple Channel Capacitive Touch Sensor and LED Driver General Description The CAP1114, which incorporates SMSC’s RightTouchTM1 technology, is a multiple channel Capacitive Touch sensor and LED Driver. The CAP1114 contains up to fourteen (14) individual Capacitive Touch sensor inputs with programmable sensitivity for use in touch button and slider switch applications. Each sensor also contains automatic recalibration with programmable time delays. The CAP1114 also includes internal circuitry to compensate for design and parasitic variance in un- touched capacitance on sensors. The CAP1114 also contains eleven (11) low side LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Capacitive buttons can be linked to LED outputs. Applications Consumer Electronics Desktop and Notebook PCs LCD Monitors Features Fourteen (14) capacitive touch sensor inputs — Compensates for variable sensor capacitance — Programmable sensitivity — High SNR allows for easy tuning — Automatic recalibration — Slider acceleration detection — Slider positional detection — Proximity detection Lid closure detection Low power operation — 4.5uA quiescent current in Deep Sleep — 200uA quiescent current in Sleep while monitoring 1 button Alert to signal touch to host processor User controlled reset Low external component count SMBus 2.0 compliant interface to change operating parameters to work in a wide variety of systems — Block Read and Write function for quick tasking Eleven (11) LED driver outputs — Programmable blink, breathe, and dimness controls — 8 configurable as GPIOs — Buttons can be linked to LED responses Development boards and software available Available in 32-pin 5mm x 5mm QFN Lead-free RoHS Compliant package Block Diagram 1.
