Slow RC Oscillator
Ultra Low Power RC Oscillator
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Table 9-2 on page
Table 9-2.
Notes:
The Slow RC Oscillator provides a 131 kHz clock (typical value, refer to section
acteristics” on page
be used as a timing reference for run-time calibration of the Fast RC Oscillator and for accu-
rately determining the actual ULP Oscillator frequency, refer to
Interface” on page 29
To provide good accuracy when used as a timing reference, the Slow RC Oscillator has calibra-
tion bytes stored in the signature address space, refer to section
from Software” on page 199
as a function of temperature is given by:
where T is the die temperature in Kelvin and T
nature row. The die temperature can be found using the Voltage ADC, refer to section
ADC – 7-channel General Purpose 12-bit Sigma-Delta ADC” on page 117
The Ultra Low Power RC Oscillator (ULP Oscillator) provides a 128 kHz clock (typical value,
refer to section
the Watchdog Timer and Battery Protection modules. The actual ULP Oscillator frequency
depends on process variations and temperature, see
The Oscillator is automatically enabled in all operational modes. It is also enabled during reset.
There are two alternative methods for determining the actual clock period of the ULP Oscillator:
