eKT2101QN32J

Touch Sensor IC - High Sensitivity; Operating voltage : 3V~5.5V, Ripple < 300mVpp\nPower-on reset time : Stable time for operating <350ms, the touchpad will send ¨Packet Hello〃 after initialization\nInterface features : Serial Peripheral Interface (SPI Slave) and I2C-slave (Normal Mode)\nOperating mode: (@ 5V)\nUseful information\nKey buttons information can be acquired through I/O transition or protocol decode.Sensitivity: sensitivity can be adjusted from 00H to 0FH for different thickness of the plastic or glass cover. The default label is ¨07H〃.\nPackage type:\n32-pin QFN 5x5 : eKT2101QN32J28-pin SOP 300mil : eKT2101SO28J24-pin SOP 300mil : eKT2101SO24J16-pin SOP 150mil : eKT2101SO16AJ\n;

The eKT2101 is low-cost single chip solution for capacitive touchpad. It is 8-bit RISC architecture microcontroller devices with Serial Peripheral Interface (SPI-Slave), I2C-slave (Normal Mode).\n For function application, the Ekt2101 support Button information for customers.In operation mode, Ekt2101 can support Protocol and I/O mode for customer. Developer can use I/O mode to get a valid button message and develop their system very easily, and no longer need to decode the communication package.\n The capacitive touchpad sensor is covered with a plastic or glass case.It provides auto-calibrate the parameter for a wide range of capacitance on the touchpad sensor (5pF~35pF). The system controller converts finger data to button presses, depending on finger location and human interface context.\n The Ekt2101 supports multi-package for various application. Package types are QFP(32 pin) and SOP(28/24/16 pin).

The eKTF5705 basic key number supports up to 16 touch buttons which is applicable to One-Line type touch sensors. \n \nFor Slider application, 2-key, 4-key, & 8-key per slider and 8-key in dual slider are supported.User can select one type for his application.The slider function is provided with 4~32 levels of sliding resolution. In addition to slider, the system also supports up to 14 touch buttons.\n\nIf the application needs more than 32 touch buttons, user should choose the 48-key library appropriately.Maximum of 48-TouchKey is supported which can be applied to Two-Line type touch sensors.\n \nThe eKTF5705 can auto-calibrate the parameters for a wide range of capacitance on the touch button sensor. After power-on, automatic adjustment of the external environment, not just touch gestures influence. If the sensor environmental conditions are changed (temperature/shift, etc.), it will automatically recalibrate the sensor capacitance to adjust and compensate capacitance shift. It supports touch sensor for small surface area or sketchpad sensor width relatively small distance, allowing small 3C product design. The sensor cable length can be quite large-scale, and supports the need for large-volume products. It can be compatible with multi-product program design.\n
