CY8C20110, CY8C20180, CY8C20160 CY8C20140, CY8C20142 CapSense Express Button Capacitive Controllers CapSense Express Button Capacitive Controllers Features Overview 10/8/6/4 capacitive button input These CapSense Express controllers support four to ten capacitive sensing (CapSense) buttons. The device functionality Robust sensing algorithm 2 is configured through an I C port and can be stored in onboard High sensitivity, low noise nonvolatile memory for automatic loading at power-on. The Immunity to RF and AC noise CY8C20110 is optimized for dimming LEDs in 15 selectable duty Low radiated EMC noise cycles for back light applications. The device can be configured Supports wide range of input capacitance, sensor shapes, to have up to 10 GPIOs connected to the PWM output. The PWM and sizes duty cycle is programmable for variable LED intensities. Target applications The four key blocks that make up these devices are: a robust Printers capacitive sensing core with high immunity against radiated and Cellular handsets conductive noise, control registers with nonvolatile storage, 2 LCD monitors configurable outputs, and I C communications. The user can configure registers with parameters needed to adjust the Portable DVD players operation and sensitivity of the CapSense buttons and outputs Low operating current 2 and permanently store the settings. The standard I C serial Active current: continuous sensor scan: 1.5 mA communication interface enables the host to configure the 2 Deep sleep current: 4 A device and read sensor information in real time. The I C address is fully configurable without any external hardware strapping. Industry s best configurability Custom sensor tuning, one optional capacitor Output supports strong drive for LED 2 Output state can be controlled through I C or directly from CapSense input state 2 Run time reconfigurable over I C 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 2 I C communication Supported from 1.8 V Internal pull-up resistor support option Data rate up to 400 kbps 2 Configurable I C addressing Industrial temperature range: 40 C to +85 C Available in 16-pin QFN, 8-pin, and 16-pin SOIC packages Errata: For information on silicon errata, see Errata on page 40. Details include trigger conditions, devices affected, and proposed workaround.
