General Description
2. General Description
The IT7230/7231 is one programmable controller with capacitance sensors which is used to implement
functions such as buttons, scroll bars, and wheels. One single electrode capacitance-to-digital converter (CDC)
is integrated into this controller.
The IT7230/7231 also provides a post-processing with CDC, and it can automatically calibrate and compensate
the front-end CDC values for environmental changes. It also modifies the threshold and sensitivity levels
automatically. The chip supports one interrupt output indicated that the CDC value over the user programming
sensitivity level. It also supports two touch detection outputs indicated that the two corresponding sensor inputs
over the default sensitivity level. The default sensitivity level can be automatically setting by the internal
environment detection circuit without any software programming. So the user can use the two outputs to control
the power-on or system reset function.
The IT7230/7231 supports one I2C compatible interface to communicate with the host. It also supports two
address select pins to specify the device ID addresses. Through this interface, the host can program the internal
controlled registers to configure this chip to meet users’ requirements. Furthermore, GPIO and current-control
functions are supported to indicate the specific status or LED dimming by the user’s definition.
The IT7230/7231 is available in 40-pad, 5 mm x 5 mm QFN package type and 24-pad, 4 mm x 4 mm QFN
package type. And it operates with only one 2.5V~3.6V power supply.
