TouchXpress™ Family

CPT112S Data Sheet

The CPT112S device, part of the TouchXpress family, is designed

to quickly add capacitive touch via an I2C interface by eliminating

the firmware complexity and reducing the development time for ca-

pacitive sensing applications.

KEY FEATURES

• No firmware development required

• Simple GUI-based configurator

• 12 Capacitive Sensor inputs with

programmable sensitivity

Supporting up to 12 capacitive sensor inputs in packages as small as a 3 mm x 3 mm

QFN, the CPT112S is a highly-integrated device that interfaces via I2C to the host pro-

cessor to provide a simple solution for adding capacitive touch. The device also comes

with advanced features like moisture immunity, wake-on proximity, and buzzer feedback

for an enhanced user experience. No firmware development is needed, and all the ca-

pacitive touch sense parameters can be configured using a simple GUI-based configura-

tor. By eliminating the need for complex firmware development, the CPT112S device en-

ables rapid user interface designs with minimal development effort.

• Configurable multi-button slider

• I2C interface to communicate to the host

• Lowest power capacitive sense solution

• Active — 200 µA

• Sleep — 1 µA

• Wake on proximity

• Superior noise immunity: SNR up to 270:1

• Moisture immunity

The CPT112S device is ideal for a wide range of capacitive touch applications including

the following:

• Mutually-exclusive touch qualifier

• Medical equipment

• Home appliances

• Button touch time-out to avoid false

touches

• Consumer electronics

• Instrument / Control panels

• Buzzer output for audible touch feedback

• Lighting control

• White goods
