CY8C20111-SX1I

Product Summary

The CY8C20111-SX1I is a controller. The CapSense Express controllers support two capacitive sensing (CapSense) buttons and two general purpose outputs in CY8C20111-SX1I and one CapSense button and one general purpose output in CY8C20111-SX1I. The CY8C20111-SX1I 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.
