Product details

Description

Configurable as CapSense or GPIO Configurable as CapSense or GPIO I2C clock I2C data Configurable as CapSense or GPIO Configurable as CapSense or GPIO Ground connection Configurable as CapSense or GPIO Configurable as CapSense or GPIO Configurable as CapSense or GPIO Active HIGH external reset with internal pull down Configurable as CapSense or GPIO Supply voltage Configurable as CapSense or GPIO Integrating capacitor input.The external capacitance is required only if 5:1 SNR cannot be achieved.

Features

Overview The CapSense ExpressTM controller allows the control of 4 IOs configurable as capacitive sensing buttons or as GPIOs for driving LEDs or interrupt signals based on various button conditions. The GPIOs are also configurable for waking up the device from sleep based on an interrupt input. The user has the ability to configure buttons, outputs, and parameters, through specific commands sent to the I2C port. The IOs have the flexibility in mapping to capacitive buttons and as standar.
