Chapter 4 General Description
The CAP1208 is a multiple channel capacitive touch sensor. It contains eight (8) individual capacitive
touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor
input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to
compensate for gradual environmental changes.
The CAP1208 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, a status bit is set and an interrupt
is generated.
The CAP1208 has Active and Standby states, each with its own sensor input configuration controls.
Power consumption in the Standby state is dependent on the number of sensor inputs enabled as well
as averaging, 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.
The device communicates with a host controller using SMBus / I2C. The host controller may poll the
device for updated information at any time or it may configure the device to flag an interrupt whenever
a touch is detected on any sensor pad.
A typical system diagram is shown in Figure 4.1.
