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.
Supporting up to 12 capacitive sensor inputs in a 3 mm x 3 mm QFN package, the
CPT112S is a highly-integrated device that interfaces via I2C to the host processor to
provide a simple solution for adding capacitive touch. The device also comes with ad-
vanced features like moisture immunity, wake-on proximity, and buzzer feedback for an
enhanced user experience. No firmware development is needed, and all the capacitive
touch sense parameters can be configured using a simple GUI-based configurator. By
eliminating the need for complex firmware development, the CPT112S device enables
rapid user interface designs with minimal development effort.
The CPT112S device is ideal for a wide range of capacitive touch applications including
the following:
• Home appliances
• Instrument / Control panels
• White goods
• Medical equipment
• Consumer electronics
• Lighting control
KEY FEATURES
