CY8C201A0 CapSense Express Slider Capacitive Controllers CapSense Express Slider Capacitive Controllers Wide range of operating voltages Features 2.4 V to 2.9 V Capacitive slider and button input 3.10 V to 3.6 V Choice of configurations: 4.75 V to 5.25 V 10-segment slider 2 I C communication 5-segment slider with remaining five pins configurable as Supported from 1.8 V CapSense or GPIO Internal pull-up resistor support option Robust sensing algorithm Data rate up to 400 kbps High sensitivity, low noise 2 Configurable I C addressing Immunity to RF and AC noise. Industrial temperature range: 40 C to +85 C Low radiated EMC noise Supports wide range of input capacitance, sensor shapes, Available in 16-pin QFN and 16-pin SOIC Package and sizes Overview Target applications Printers These CapSense Express controllers support four to ten Cellular handsets capacitive sensing CapSense buttons. The device functionality LCD monitors 2 is configured through an I C port and can be stored in the Portable DVD players onboard nonvolatile memory for automatic loading at power on. The CapSense Express controller enables the control of 10 I/Os Low operating current 1 configurable as one capacitive sensing slider (10 segments) or Active current: continuous sensor scan: 1.5 mA one slider (5 segments) with the rest of the pins as buttons or Deep sleep current: 4 A GPIOs (for driving LEDs or interrupt signals based on various Industry s best configurability button conditions). Custom sensor tuning, one optional capacitor The four key blocks that make up these devices are: a robust Output supports strong drive for LED capacitive sensing core with high immunity against radiated and 2 Output state can be controlled through I C or directly from conductive noise, control registers with nonvolatile storage, 2 CapSense input state configurable outputs, and I C communications. The user can 2 Run time reconfigurable over I C configure registers with parameters needed to adjust the operation and sensitivity of the CapSense buttons and outputs Advanced features 2 and permanently store the settings. The standard I C serial Interrupt outputs communication interface enables the host to configure the 2 User defined Inputs device and to read sensor information in real time. The I C Wake on interrupt input address is fully configurable without any external hardware Sleep control pin strapping. Nonvolatile storage of custom settings Easy integration into existing products configure output to match system No external components required World-class free configuration tool Note 1. This part should be selected only if the design requires a slider. This part cannot be configured to work without a slider. For 10 I/O requirements use CY8C20110.
