general description

CAP1203 is a multi-channel capacitive touch

sensor controller. it contains personal capacitive touch

Sensor input with programmable sensitivity for

Contact sensor applications. Each sensor input is calibrated to compensate for system parasitic capacitance

And automatically recalibrates to compensate for gradual changes in the environment.

The CAP1203 includes multi-modal touch recognition, allowing the user to select a specific set of buttons to be touched at the same time. If this mode is

detected, a status bit is set and an interrupt is generated.

CAP1203 has two states: Active and Standby

Has its own sensor input configuration control. that power

Consumption in Standby state depends on

the number of sensor inputs enabled and the average value,

Sample time and cycle time. Deep sleep is the lowest power state available and draws 5µA (typ). In this state, no sensor input is active

Communication will wake the device.
