3.2 Clocking 

The Kinetis microcontrollers start up from an internal digitally controlled oscillator (DCO). The 
software can enable one or two external oscillators if required. The external oscillator for the 
Multipurpose Clock Generator (MCG) module can range from 32.768 kHz up to a 32 MHz crystal or 
ceramic resonator. The external oscillator for the Real-Time Clock (RTC) module accepts a 32.768 kHz 
crystal. 

Two crystals are provided on-board for clocking the K65F180M device: a 16 MHz crystal as the main 
oscillator to clock the MCG module and a 32.768 kHz crystal for clocking the RTC module. 

 

 

NOTE  

The on-chip HS USB PHY requires a 12, 16, or 24 MHz crystal with the 
main oscillator on EXTAL0 and XTAL0 pins.  

3.3     System power 

In standalone operation, the main power source for the TWR-K65F180M is derived from the 5.0 V input 
from either the USB mini-B connector, J7, or the debugger header, J18, when a shunt is placed on 
jumper J21. An on-board low-dropout regulator provides either 3.3 V or 1.8 V supply from the 5.0 V
