For timing insensitive applications, it is possible to use the fully integrated RC-oscillator 1. It
operates without any external components and saves additional costs. The RC-oscillator 1 cen-
ter frequency tolerance is better than ±50% over the full temperature and voltage range. A
reduction in the application operating supply voltage and temperature ranges will result in
improved frequency tolerance. For more detailed information see
