| Long term stability of the internal RC oscillator of the LPC900 family |
|
The accuracy of the internal RC oscillator is for the LPC900 temperature range +/- 2,5% and +/- 1% at room temperature.
Does anyone knows the long term stability of the internal oscillator ?
It would not be nice when the LPC900 processor cannot communicate with a PC via RS232 any longer (e.g. after 5 years) due to a baudrate tolerance problem caused by the drifting RC oscillator frequency.
