Low frequency oscillator IP

Low-power ICs impose on designers the implementation of an efficient wake-up system, sufficiently accurate from a time tracking point-of-view, to ensure for instance that paired wireless devices operate in the same time-window. The higher the clock drift, the earlier a slave device needs to wake-up, thereby wasting significant power consumption over time.

Dolphin Integration’s low frequency oscillator IPs, specifically designed for the Always-On Domain, provide unprecedented optimization capabilities to designers needing to find the best compromise between ultra-low power consumption, low BoM cost, high accuracy of frequency setting and fast power-up.

Real Time Clock IP: RTC-32k-CAL.01

The RTC-32k-CAL.01 is a low power Real Time Clock relying on a crystal oscillator and designed to achieve the requirements of low power modes and deep sleep modes of IoT devices. Together with the qOSC-XTAL-LP-32k-co.01 it will allow the user to achieve the lowest power consumption for the Always-On domain.

The RTC-32k-CAL.01 is provided with a large set of programmable functions, such as calendar, alarms, interrupts…
