Overview

The TWR-K20D50MTWR-K20D50M module is a development board for the Kinetis K10 and K20 50MHz 32-bit ARM® Cortex™-M4 MCUs and provides rapid prototyping for applications requiring high feature integration and low power consumption. The TWR-K20D50M operates as a standalone debug tool and can also be combined and used as part of the modular Tower System development platform.Take your design to the next level and begin constructing your Tower System today.

The TWR-K20D50MTWR-K20D50M features two pushbutton switches connected to GPIO/interrupt signals, one pushbutton connected to the master reset signal, two capacitive touch pad electrodes, four user‐controllable LEDs, and a potentiometer connected to an ADC input signal.

The TWR-K20D50MTWR-K20D50M Tower MCU Module features MK20DX128VLH5MK20DX128VLH5 — a Kinetis microcontroller with USB 2.0 full‐speed OTG controllers. It is intended for use in the Freescale Tower System but can operate stand‐alone. An on‐board debug circuit, OSJTAG, provides a JTAG interface and a power supply input through a single USB mini‐AB connector.

The Kinetis MCUs start up from an internal digitally controlled oscillator (DCO). Software can enable the main external oscillator (EXTAL0/XTAL0) if desired. The external oscillator/resonator can range from 32.768 KHz up to a 32 MHz. An 8 MHz crystal is the default external source for the MCG oscillator inputs (XTAL/EXTAL). A 32.768 KHz crystal is connected to the RTC oscillator inputs by default.

The touch sensing input (TSI) module of the K20DX128VLH5 MCUs provides capacitive touch sensing detection with high sensitivity and enhanced robustness. Each TSI pin implements the capacitive measurement of an electrode. The TWR-K20D50MTWR-K20D50M provides two methods for evaluating the TSI module. There are two electrodes on‐board. Additionally, 12 TSI signals are connected to a Touch Tower Plug‐in (TWRPI) socket (J5) that can accept Touch TWRPI daughter cards that may feature keypads, rotary dials, sliders, etc.

Key Applications: Barcode scanners, Portable media players, Printers, Programmable logic controllers
