Calibrated Internal
RC Oscillator
2466T–AVR–07/10
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Table
Table 8. Start-up Times for the External RC Oscillator Clock Selection
Note:
The Calibrated Internal RC Oscillator provides a fixed 1.0 MHz, 2.0 MHz, 4.0 MHz, or 8.0 MHz
clock. All frequencies are nominal values at 5V and 25°C. This clock may be selected as the
system-clock by programming the CKSEL Fuses as shown in
with no external components. The CKOPT Fuse should always be unpro-grammed when using
this clock option. During Reset, hardware loads the calibration byte into the OSCCAL Register
and thereby automatically calibrates the RC Oscillator. At 5V, 25°C and 1.0 MHz, 2.0 MHz, 4.0
MHz or 8.0 MHz Oscillator frequency selected, this calibration gives a frequency within ±3% of
the nominal frequency. Using calibration methods as described in application notes available at
www.atmel.com/avr it is possible to achieve ±1% accuracy at any given V
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 cali-
bration value, see the section
Table 9. Internal Calibrated RC Oscillator Operating Modes
Note:
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
