which senses the change in capacitance based on touch or

proximity, and controls the user interface system accordingly.

The sensing algorithm, built in the controllers, determines the

presence of touch and drives the outputs or sends signals to the

host processor. This algorithm can distinguish between the

signal (based on touch or proximity) and noise, which can be

caused by environmental or electrical conditions.

System Overview

Acapacitive sensor detects changes in capacitance to determine

the presence of a touch or proximity to conductive objects. The

capacitive sensor can be a capacitive button that replaces the

traditional mechanical buttons, a capacitive slider that replaces

mechanical knobs, or a proximity sensor that replaces an

infrared sensor in a user interface solution. A typical capacitive

user interface system consists of the following:

Figure 2 shows a typical user interface system with capacitive

buttons connected to a CY8CMBR3xxx CapSense Express

controller, which controls the system and also communicates

with the host processor through I²C.

■ A capacitive sensor

■ An audio-visual output, such as a buzzer or an LED

■ A capacitive sensing controller connected to the sensor

■ A host processor

Traditionally, capacitive sensing controllers require firmware

development to perform specific user interface functions and

manual system tuning to achieve optimal performance.

However, the CY8CMBR3xxx CapSense Express family of

controllers does not require any firmware development, acceler-

ating time-to-market. These devices feature SmartSense

Auto-tuning, which eliminates the need for manual tuning,

providing optimal performance even under extremely noisy

conditions.

The capacitive controller connects the sensor and the output to

the host processor through a communication interface, such as

an I²C or a GPO.

The capacitive user interface system serves as a

human-machine interface that takes the user’s touch inputs and

provides audio-visual feedback through a buzzer or an LED.

CY8CMBR3xxx is a family of capacitive sensing controllers,
