CY8C20121-SX1IT - Brand New Cypress Semiconductor Capacitive Touch Sensors
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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.
