The OSC-XTAL-32k-TS-22ULL.01 32 kHz crystal oscillator is an excellent choice for IoT SoC designed in TSMC 22nm ULL technology with stringent power consumption constraints. It features a high accuracy 32 kHz clock for implementing RTC with calendar and timekeeping functions in the always-on domain and an ultra-low current consumption to extend the battery lifetime in sleep modes.

Key Benefits

  • High accuracy
  • Low power consumption
  • Compatible with a large range of crystals
  • Bypass mode for enabling fast testing capabilities
  • Frequency OK (FOK) signal indicates when frequency accuracy is reached
