2.9 General Purpose Tower Plug-in (TWRPI) Socket
The TWR-K60F120M features a socket that can accept a variety of different Tower Plug-in modules
featuring sensors, RF transceivers, and more. The General Purpose TWRPI socket provides access to
I2C, SPI, IRQs, GPIOs, timers, analog conversion signals, TWRPI ID signals, reset, and voltage supplies.
The pinout for the TWRPI Socket is defined in Table 2.
Refer to Table 6 “I/O Connectors and Pin Usage Table” for the specific K60 pin connections to the
General Purpose TWRPI socket.

2.10 Touch Interface
The touch sensing input (TSI) module of the Kinetis MCUs provides capacitive touch sensing detection
with high sensitivity and enhanced robustness. Each TSI pin implements the capacitive measurement of
an electrode.
The TWR-K60F120M provides two methods for evaluating the TSI module. There are four individual
electrodes on-board the TWR-K60F120M that simulate pushbuttons. Additionally, twelve TSI signals
are connected to a Touch Tower Plug-in (TWRPI) socket that can accept Touch TWRPI daughter cards
that may feature keypads, rotary dials, sliders, etc.
The pinout for the Touch TWRPI socket is defined in Table 3. Refer to Table 6 “I/O Connectors and Pin
Usage Table” for the specific K60 pin connections to the Touch TWRPI socket.
