Calibrated Internal RC
Oscillator
2466J–AVR–10/04
Table 7. External RC Oscillator Operating Modes
When this Oscillator is selected, start-up times are determined by the SUT Fuses as
shown in Table 8.
Table 8. Start-up Times for the External RC Oscillator Clock Selection
Note:
The Calibrated Internal RC Oscillator provides a fixed 1.0, 2.0, 4.0, or 8.0 MHz clock. All
frequencies are nominal values at 5V and 25°C. This clock may be selected as the sys-
tem clock by programming the CKSEL Fuses as shown in Table 9. If selected, it will
operate 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 Oscillator frequency selected, this calibration gives a fre-
quency 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
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 the section “Calibra-
tion Byte” on page 261.

Note:
When this Oscillator is selected, start-up times are determined by the SUT Fuses as
shown in Table 10. XTAL1 and XTAL2 should be left unconnected (NC).
