range of –40°C to 85°C
and temperature
RAM and flash contents
unused modules, thereby reducing currents
and stop modes with internal clock sources
module containing a frequency-locked-loop (FLL)
controlled by internal reference; precision trimming of
internal reference allows 0.2% resolution and 2%
deviation over temperature and voltage; supports bus
frequencies from 1 MHz to 10 MHz
with option to run from dedicated 1 kHz internal clock
source or bus clock
