42 / 210 page  Functional overview STM32L452xx 42/210 DocID029968 Rev 3 The main features of the touch sensing controller are the following: • Proven and robust surface charge transfer acquisition principle • Supports up to 21 capacitive sensing channels • Up to 3 capacitive sensing channels can be acquired in parallel offering a very good response time • Spread spectrum feature to improve system robustness in noisy environments • Full hardware management of the charge transfer acquisition sequence • Programmable charge transfer frequency • Programmable sampling capacitor I/O pin • Programmable channel I/O pin • Programmable max count value to avoid long acquisition when a channel is faulty • Dedicated end of acquisition and max count error flags with interrupt capability • One sampling capacitor for up to 3 capacitive sensing channels to reduce the system components • Compatible with proximity, touchkey, linear and rotary touch sensor implementation • Designed to operate with STMTouch touch sensing firmware library Note: The number of capacitive sensing channels is dependent on the size of the packages and subject to I/O availability. 3.21 Digital filter for Sigma-Delta Modulators (DFSDM) The device embeds one DFSDM with 2 digital filters modules and 4 external input serial channels (transceivers) or alternately 4 internal parallel inputs support. The DFSDM peripheral is dedicated to interface the external Σ∆ modulators to microcontroller and then to perform digital filtering of the received data streams (which represent analog value on Σ∆ modulators inputs). DFSDM can also interface PDM (Pulse Density Modulation) microphones and perform PDM to PCM conversion and filtering in |
