Silicon Labs' latest TouchXpress capacitive touch controllers now at Mouser

Published: 25 August 2017 - Sarah Mead

Mouser Electronics, Inc., the authorised global distributor with the newest semiconductors and electronic components, is now stocking the CPT212B and CPT213B TouchXpress capacitive touch controllers from Silicon Labs. The CPT212B and CPT213B TouchXpress controllers eliminate time-consuming firmware development, providing a simple turnkey solution for adding touch-based designs to a wide range of products, including home appliances, medical equipment, consumer electronics, instrument and control panels, and lighting control.

The Silicon Labs CPT212B and CPT213B TouchXpress controllers, available from Mouser Electronics, provide a fast and easy way for design engineers to add low-power capacitive touch interfaces to embedded designs. The CPT212B device features up to 12 sensor inputs and boasts ultra-low-power operation, rated at 200 µA in optimised active mode and 1 µA in sleep mode. The CPT213B device offers up to 13 sensor inputs and adds IEC 60730 Class B safety library support, designed for preventing unsafe operation of household appliances. The controllers’ I2C interface provides an easy way to track the status of touch sensors, and an interrupt pin can wake the host processor from sleep after a proximity touch detection.

Mouser is also stocking the evaluation boards that showcase the capabilities of the TouchXpress controllers. The CPT212B SLEXP8018A evaluation board features 12 capacitive sense pads and CPT213B SLEXP8019A evaluation board features a capacitive sensing input engine with 13 inputs. Both boards include a buzzer for touch feedback, touch qualification engine, and an expansion header for connecting to Silicon Labs EFM8 or EFM32 starter kits.
