Revision History ........................................................... 15 for serial communications, flash programming and run- control debugging. The FRDM-KL28Z hardware is form-factor compatible with the Arduino R3 pin layout, providing a broad range of expansion board options. The on-board interfaces include an RGB LED, a 6-axis digital sensor (combining a 3D accelerometer and 3D magnetometer), a 3-axis digital angular rate gyroscope, an ambient light sensor, and a capacitive touch slider. There are many software development tool options available to the user. Choices include Kinetis Design Studio (KDS), IAR Embedded Workbench, Keil MDK featuring the Vision IDE, and so on. All of these features combine to give users the freedom needed to rapidly prototype many embedded designs: a 2016 NXP B.V. FRDM-KL28Z Features powerful microcontroller built on a very low-power core and SOC platform, easy-access to I/O with a large ecosystem of compatible hardware, a flexible programming and debug interface, and a large ecosystem of software development environments. 2. Getting Started Refer to the FRDM-KL28Z Quick Start Package for step-by-step instructions for getting started with the freedom board. See the Jump Start Your Design section at nxp.com/FREDEVPLA for the Quick Start Package and software lab guides. 3. FRDM-KL28Z Features The FRDM-KL28Z hardware is a Freedom development board assembled with the following features: MKL28Z512VLL7 MCU (96 MHz, 512 KB Flash, 128 KB RAM, 32 KB ROM,100 LQFP package) 3-Axis Digital Angular Rate Gyroscope, FXAS21002CQ (U2) Accelerometer and magnetometer, FXOS8700CQ (U10) OpenSDA: On-board serial and debug adapter (U7) I/O headers for easy access to MCU I/O pins Ambient light sensor (Q1) Flexible power supply options: USB, coin cell battery, external source Capacitive touch slider Reset push button (SW1) NMI and LLWU buttons (SW2, SW3) RGB LED (D2) The FRDM-KL28Z features two MCUs: The target MCU is the MKL28Z512VLL7. The OpenSDA MCU is the MK20DX128VFM5. The primary components and their location on the hardware assembly are pointed out in Figure 1. Figure 2 shows a block diagram of the FRDM-KL28Z board.
