Product Details

Overview

The CapSense® Express™ controllers support two capacitive sensing (CapSense) buttons and two general purpose outputs in CY8C20121 and one CapSense button and one general purpose output in CY8C20111. The device functionality is configured through the I2C port and can be stored in on-board nonvolatile memory for automatic loading at power on. The digital outputs are controlled from CapSense inputs in factory default settings, but are user configurable for direct control through I2C.
The four key blocks that make up the CY8C20111 and CY8C20121 controllers are: a robust capacitive sensing core with high immunity against radiated and conductive noise, control registers with nonvolatile storage, configurable outputs, and I2C communications. The user can configure registers with parameters needed to adjust the operation and sensitivity of the CapSense buttons and outputs and permanently store the settings. The standard I2C serial communication interface allows the host to configure the device and read sensor information in real time. I2C address is fully configurable without any external hardware strapping.
