Product data sheet
7.17.1 Integrated oscillators
7.17 Clocking and power control
The LPC11U3x include three independent oscillators: the system oscillator, the Internal
RC oscillator (IRC), and the watchdog oscillator. Each oscillator can be used for more
than one purpose as required in a particular application.
Following reset, the LPC11U3x operates from the internal RC oscillator until software
switches to a different clock source. The IRC allows the system to operate without any
external crystal and the bootloader code to operate at a known frequency.
