32 kHz RC oscillator based on GF 22FDX+ process. Low-power architecture for the implementation of always-on domains. The IP informs the host when the frequency has reached a stable frequency value after leaving shutdown or standby mode.
Key Benefits
- Low-power architecture
- Extened frequency trimming
- Flag when stable frequency reached
- Standby mode with quick wake-up time
- Shutdown mode
