Ultra-low power and high accuracy crystal oscillator to generate a 32 kHz clock in the Always-on domain with minimum power consumption. Perfect fit for IoT applications with stringent power consumption in sleep and deep sleep modes.

Key Benefits

  • Low power consumption: support of low power and backup modes
  • High accuracy: can operate in various environment thanks to its outstanding stability over a large range of temperature
  • A cost-efficient solution: no external component is needed (except a quartz) thanks to on-chip integrated capacitors.
  • A flexible solution: users have the possibility to add capacitors depending on the external crystal selected for a better frequency fitting
  • By-Pass Mode: the oscillator could be by-passed during tests
