Product overview

3.18

ProxSense

The ProxSense peripheral uses a charge-transfer method to detect capacitance changes.



Up to 300 capacitive sensing channels composed of 15 transmitters and 20 receivers

with up to 10 Rx channels acquired in parallel



Fast acquisition with a typical scan time of 250 µs for 10 Rx channels



Configurable internal sampling capacitor (CS)



Electrode Parasitic Capacitance Compensation (EPCC) to ensure the best sensitivity in

all user environments



RF noise detection, allowing to reject corrupted samples



External trigger to de-synchronize the acquisition from known noise



Can be configured to return to low power mode between each conversion



Acquisition possible in Run, Wait and Active-halt modes

3.19

TouchSensing dedicated library available upon request



Complete C source code library with firmware examples (MISRA compliant)



Multifunction capability to combine capacitive sensing functions with traditional MCU

features



Compatible with proximity, touchkey, linear and rotary touch sensor implementation



Configuration of all ProxSense parameters



Extra filtering and calibration functions



TouchSensing user interface through firmware API for status reporting and application

configuration



Compliance with Cosmic, IAR and Raisonance C compilers
