TouchXpress Family CPT213B Data Sheet The CPT213B device, part of the TouchXpress family, is designed KEY FEATURES to quickly add IEC 60730 Class B capacitive touch via an I2C in- terface by eliminating the firmware complexity and reducing the No firmware development required development time for capacitive sensing applications. Simple GUI-based configurator 13 Capacitive Sensor inputs with Supporting up to 13 capacitive sensor inputs in packages as small as a 4 mm x 4 mm programmable sensitivity QFN, the CPT213B is a highly-integrated device that interfaces via I2C to the host pro- IEC-compliant I2C interface to cessor to provide a simple solution for adding capacitive touch. The device also comes communicate to and configure from the with advanced features like an IEC safety library and moisture immunity. No firmware de- host velopment is needed, and all the capacitive touch sense parameters can be configured IEC 60730 Class B safety library using a simple GUI-based configurator. By eliminating the need for complex firmware de- Superior noise immunity: SNR up to 270:1 velopment, the CPT213B device enables rapid user interface designs with minimal de- Moisture immunity velopment effort. The CPT213B device is ideal for a wide range of capacitive touch applications including the following: Medical equipment Home appliances Lighting control White goods Instrument / Control panels Input Capacitive Touch Sensing Output Features Features Features Touch IEC Safety IEC-Compliant I2C Event Buffer Qualification Library I2C Output Input Engine with 13 Inputs Configuration Profile for each Baselining Interrupt Pin Input Lowest power mode with feature operational: Active silabs.com Building a more connected world.
