Internal Precision Oscillator
PS024613-0910
Operation
The Internal Precision Oscillator (IPO) is designed for use without external components.
The IPO comes factory trimmed 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 which 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. Two 8-bit trimming registers,
incorporated into the design, allow compensation of absolute variation of oscillator
frequency. Once 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 can override these trim values as described in
On-chip RC oscillator that does not require external components.
Trimmed to ±4% accuracy.
Target output frequency of 5.5296 MHz.
Trimming possible through Flash option bits with user override.
IPO can eliminate crystals or ceramic resonators in applications where high timing
accuracy is not required.
