About CAPSENSE™ Express

CAPSENSE™ Express controllers support four to ten capacitive sensing (CAPSENSE™) buttons. The device functionality is configured through an I2C port and can be stored in onboard nonvolatile memory for automatic loading at power-on. 

The CY8C20110 is optimized for dimming LEDs in 15 selectable duty cycles for back light applications. The device can be configured to have up to 10 GPIOs connected to the PWM output. The PWM duty cycle is programmable for variable LED intensities.

CAPSENSE™ Express blocks

The four key blocks that make up these devices are: 

  • A robust capacitive sensing core with high immunity against radiated and conductive noise
  • Control registers with nonvolatile storage
  • Configurable outputs
  • 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 enables the host to configure the device and read sensor information in real time. The I2C address is fully configurable without any external hardware strapping.

Features

10/8/6/4 capacitive button input

  • Robust sensing algorithm
  • High sensitivity and low noise
  • Immunity to RF and AC noise
  • Low radiated EMC noise
  • Supports wide range of input capacitance, sensor shapes, and sizes

Low operating current

  • Active current: continuous sensor scan: 1.5 mA
  • Deep sleep current: 4 µA

Configurability

  • Custom sensor tuning, one optional capacitor 
  • Output supports strong drive for LED
  • Output state can be controlled through I2C or directly from CAPSENSE™ input state
  • Run time reconfigurable over I2C

Advanced features 

  • All GPIOs support LED dimming with configurable delay option in CY8C20110
  • Interrupt outputs
  • User defined inputs
  • Wake on interrupt input
  • Sleep control pin
  • Nonvolatile storage of custom settings 
  • Easy integration into existing products – configure output to match system
  • No external components required
  • World-class free configuration tool

 

Wide range of operating voltages

  • 2.4 V to 2.9 V
  • 3.10 V to 3.6 V
  • 4.75 V to 5.25 V
