OSCILLATOR: The oscillator SGC21543 is a programmable ring oscillator optimized for ultra low power applications. It as been optimized to work from 10 kHz to 10 MHz. The and uses a current controlled ring oscillator topology to achieve both ultra low power consumption and high noise immunity. For 32 kHz low precision RTC applications the SGC21543 can operate for weeks from the charge of a single super capacitor. It is specified from Tj = -40 °C to +125 °C.
