Calibrated Internal RC Oscillator
The calibrated internal RC Oscillator by default provides a 8.0MHz clock. The frequency is
nominal value at 5V and 25°C. The device is shipped with the CKDIV8 Fuse programmed.
See
system clock by programming the CKSEL Fuses as shown in
operate with no external components. During reset, hardware loads the calibration byte into
the OSCCAL Register and thereby automatically calibrates the RC Oscillator. At 5V and 25 C,
this calibration gives a frequency of 8MHz ±1%. The tolerance of the internal RC oscillator
remains better than ±10% within the whole automotive temperature and voltage ranges (4.5V
to 5.5V, –40°C to +125°C). The oscillator can be calibrated to any frequency in the range
7.3 - 8.1MHz within ±1% accuracy, by changing the OSCCAL register. When this Oscillator is
used as the chip clock, the Watchdog Oscillator will still be used for the Watchdog Timer and
for the Reset Time-out. For more information on the pre-programmed calibration value (see
“Calibration Byte” on page
Table 6-11.
Notes:
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
