Internal Precision Oscillator
Operation
PS024314-0308
The internal precision oscillator (IPO) is designed for use without external components.
You can either manually trim the oscillator for a non-standard frequency or use the
automatic factory-trimmed version to achieve a 5.53 MHz frequency. The features of IPO
include:
•
•
•
•
An 8-bit trimming register, incorporated into the design, compensates for absolute varia-
tion of oscillator frequency. Once trimmed the oscillator frequency is stable and does not
require subsequent calibration. Trimming is performed during manufacturing and is not
necessary for you to repeat unless a frequency other than 5.53 MHz (fast mode) or 32.8
kHz (slow mode) is required. This trimming is done at +30 °C and a supply voltage of 3.3
V, so accuracy of this operating point is optimal.
Power down this block for minimum system power. By default, the oscillator is configured
through the Flash Option bits. However, the user code can override these trim values as
described in
Select one of the two frequencies for the oscillator: 5.53 MHz and 32.8 kHz, using the
OSCSEL bits in the
On-chip RC oscillator that does not require external components
Output frequency of either 5.53 MHz or 32.8 kHz (contains both a fast and a slow mode)
Trimming possible through Flash option bits with user override
Elimination of crystals or ceramic resonators in applications where high timing accuracy
is not required
