Calibrated Internal RC Oscillator
The capacitance (Ce + Ci) needed at each XTAL/TOSC pin can be calculated by using:
where:
Ce - is optional external capacitors as described in
Ci - is is the pin capacitance in
CL - is the load capacitance for a 32.768 kHz crystal specified by the crystal vendor.
C
Crystals specifying load capacitance (CL) higher than the ones given in the
45, require external capacitors applied as described in
Figure 9-3.
To find suitable load capacitance for a 32.768 kHz crysal, please consult the crystal datasheet.
When this oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0
as shown in
Table 9-8.
Note:
By default, the Internal RC Oscillator provides an approximate 8 MHz clock. Though voltage and
temperature dependent, this clock can be very accurately calibrated by the user. See
on page 371
with the CKDIV8 Fuse programmed. See
S
- is the total stray capacitance for one XTAL/TOSC pin.
