TouchXpress™ Family
CPT007B Data Sheet
The CPT007B device, part of the TouchXpress family, is designed
to quickly replace mechanical buttons with modern capacitive
touch buttons by eliminating firmware complexity and reducing de-
velopment time.
Supporting up to 7 capacitive sensor inputs in a 3 mm x 3 mm QFN package, the
CPT007B is a highly-integrated device that provides a simple solution for adding capaci-
tive touch. The device also comes with advanced features like moisture immunity, wake-
on proximity, and buzzer feedback for an enhanced user experience. No firmware devel-
opment is needed, and all the capacitive touch sense parameters can be configured us-
ing a simple GUI-based configurator. By eliminating the need for complex firmware de-
velopment, the CPT007B device enables rapid user interface designs with minimal de-
velopment effort.
The CPT007B 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
• No firmware development required
• Simple GUI-based configurator
• 7 Capacitive Sensor inputs with
programmable sensitivity
• 7 General purpose outputs (GPOs) to
communicate to the host processor or drive
LEDs
• Lowest power capacitive sense solution
• Active — 200 µA
• Sleep — 1 µA
• Wake on proximity
• Superior noise immunity: SNR up to 270:1
• Moisture immunity
• Mutually-exclusive touch qualifier
• Button touch time-out to avoid false
touches
• Buzzer output for audible touch feedback
