Description
The CAP1298 is a multiple channel capacitive touch sensor controller. It contains eight (8) individual capac- itive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input is calibrated to compensate for system parasitic capac- itance and automatically recalibrated to compensate for gradual environmental changes. In addition, the CAP1298 can be configured to detect proximity on one or more channels with an optional sig- nal guard to reduce noise sensitivity and to isolate the proximity antenna from nearby conductive surfaces that would otherwise attenuate the e-field. The CAP1298 includes Multiple Pattern Touch recogni- tion that allows the user to select a specific set of but- tons to be touched simultaneously. If this pattern is detected, a status bit is set and an interrupt is gener- ated. The CAP1298 has Active and Standby states, each with its own sensor input configuration controls. The Combo state allows a combination of sensor input con- trols to be used which enables one or more sensor inputs to operate as buttons while another sensor input is operating as a proximity detector. Power consump- tion in the Standby and Combo states is dependent on the number of sensor inputs enabled as well as averag- ing, sampling time, and cycle time. Deep Sleep is the lowest power state available, drawing 5µA (typical) of current. In this state, no sensor inputs are active, and communications will wake the device.
