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). 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.

Features
Operating voltage : 3V~5.5V, Ripple < 300mVpp
Power-on reset time : Stable time for operating < 350ms, the touchpad will send “Packet Hello” after initialization
Interface features : Serial Peripheral Interface (SPI Slave) and I2C-slave (Normal Mode)
Operating mode: (@ 5V)
Useful information
   Key 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”.
Package type:
  32-pin QFN 5x5 : eKT2101QN32J
  28-pin SOP 300mil : eKT2101SO28J
  24-pin SOP 300mil : eKT2101SO24J
