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
