LPC1311/13/42/43
32-bit ARM Cortex-M3 microcontroller
7.18.1.1
Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
system PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC
is trimmed to 1 % accuracy over the entire voltage and temperature range.
The USB clock is available on LPC1342/43 only. SSP1 is available on LPC1313FBD48/01 only.
