Revision History ........................................................... 15 embedded serial and debug adapter known as OpenSDA(CMSIS-DAP). This circuit offers the user several options for serial communications, flash programming, and run-control debugging. The TWR-KE18F microcontroller module is designed to work either in standalone mode or as part of the NXP Tower System, a modular development platform that enables rapid prototyping and tool re-use through reconfigurable hardware. There are many software development tool options available to the user. Choices include Kinetis Design Studio (KDS), IAR Embedded Workbench, and Keil MDK featuring the Vision IDE. All of these features combine to give users the Tower needed to rapidly prototype many embedded designs: a powerful microcontroller built on a very low-power core and SOC platform, easy-access to I/O with a large 2016 NXP B.V. TWR-KE18F Features ecosystem of compatible hardware, a flexible programming and debug interface, and a large ecosystem of software development environments. 2. Getting Started Refer to the TWR-KE18F Quick Start Package for step-by-step instructions for getting started with the Tower board. See the Jump Start Your Design section at nxp.com/TWR-KE18F for the Quick Start Package and software lab guides. 3. TWR-KE18F Features The TWR-KE18F hardware is a NXP Tower development board assembled with the following features: MKE18F512VLL16 MCU (168 MHz core clock, 512 KB flash, 64 KB RAM, 100LQFP package) Tower-compatible processor board Onboard OpenSDA (CMSIS-DAP) circuit: K20DX128VFM5 with debug and virtual serial port Four user-controlled status LEDs and one RGB LED Two mechanical push buttons and one reset button I/O headers for easy access to MCU I/O pins Thermistors and potentiometer FXOS8700CQ 3D accelerometer + 3D magnetometer Board power select with 3.3 V or 5 V MCU operation Infrared port communication CAN transceiver Flex I/O header The TWR-KE18F features two MCUs: The target MCU is the MKE18F512VLL16. The OpenSDA(CMSIS-DAP) MCU is the MK20DX128VFM5. Figure 1 shows the block diagram of the TWR-KE18F board. The primary components and their location on the hardware assembly are shown in Figure 2 and Figure 3. TWR-KE18F User s Guide, Rev. 0, 09/2016 2 NXP Semiconductors
