Internal Precision Oscillator
Operation
PS028702-1210
The Internal Precision Oscillator (IPO) is designed for use without external components.
Nominal untrimmed accuracy is approximately ±30%. You can manually trim the
oscillator to achieve a ±4% frequency accuracy over the operating temperature and supply
voltage range of the device.
The IPO features include:
•
•

The internal oscillator is an RC relaxation oscillator and has its sensitivity to power supply
variation minimized. By using ratio tracking thresholds, the effect of power supply voltage
is cancelled out. The dominant source of oscillator error is the absolute variance of chip
level fabricated components, such as capacitors. An 8-bit trimming register, incorporated
into the design, allows compensation of absolute variation of oscillator frequency. After it
is calibrated, the oscillator frequency is relatively stable and does not require subsequent
calibration.
By default, the oscillator is configured through the Flash Option bits. However, the user
code overrides these trim values as described in
chapter on page
