    USB host and this serial interface on the KL25Z. 5.3 KL25Z Microcontroller The target microcontroller of the FRDM-KL25Z is the KL25Z128VLK4, a Kinetis L series device in an 80 LQFP package. The KL25Z MCU features include:  32-bit ARM Cortex-M0+ core...

  • Page 9: Clock Source

    The Kinetis KL2 microcontrollers feature an on-chip oscillator compatible with three ranges of input crystal or resonator frequencies: 32-40 kHz (low freq. mode), 3-8 MHz (high freq. mode, low range) and 8-32 MHz (high freq. mode, high range). The KL25Z128 on the FRDM-KL25Z is clocked from an 8 MHz crystal.

  • Page 10: Debug

    The sole debug interface on all Kinetis L Series devices is a Serial Wire Debug (SWD) port. The primary controller of this interface on the FRDM-KL25Z is the onboard OpenSDA circuit (see section 5.2). However, an unpopulated 10-pin (0.05”) Cortex Debug connector, J6, provides access to the SWD signals.

    Note that all pinout data is available in spreadsheet format in FRDM-KL25Z Pinouts. See the Reference Documents section for details. 5.8 Arduino Compatibility The I/O headers on the FRDM-KL25Z are arranged to allow compatibility with peripheral boards (known as shields) that connect to Arduino™ and Arduino-compatible microcontroller boards. The outer rows of pins (the even numbered pins) on the headers share the same mechanical spacing and placement as the I/O headers on the Arduino Revision 3 (R3) standard.
  • Page 13 Refer to the FRDM-KL25Z Pinouts spreadsheet for a compatibility chart showing how all the functions of the KL25Z signals on the I/O connectors map to the pin functions available on the Arduino Uno R3. FRDMKL25ZUM FRDM-KL25Z User's Manual Page 13 of 14...
