External RC
Oscillator

ATmega128
For timing insensitive applications, the External RC configuration shown in
used. The frequency is roughly estimated by the equation f = 1/(3RC). C should be at least
22pF. By programming the CKOPT fuse, the user can enable an internal 36pF capacitor
between XTAL1 and GND, thereby removing the need for an external capacitor. For more infor-
mation on Oscillator operation and details on how to choose R and C, refer to the External RC
Oscillator application note.
Figure 20. External RC Configuration
The Oscillator can operate in four different modes, each optimized for a specific frequency
range. The operating mode is selected by the fuses CKSEL3..0 as shown in
Table 11. External RC Oscillator Operating Modes
When this Oscillator is selected, start-up times are determined by the SUT fuses as shown in
Table
