The Always-On domain, over which the power islets emerge, requires a specific panoply of voltage regulators and clocks. The availability of extremely low power oscillators is therefore a must.
In low power modes, low speed clocks are generally used. The qOSC-RC-LP-32k-co.01 - low frequency RC oscillator - is an excellent choice for application combining the needs of ultra-low power consumption and reduced BoM cost.
It can also be suitably combined with a crystal oscillator in order to benefit at once from fast wake-up time of the RC oscillator and from accuracy of the crystal.
Low frequency 32-kHz RC oscillator optimized for low power
Overview
Key Features
- Low power consumption: support of low power and backup modes thanks to its 70 nA typical power consumption
- A cost-efficient solution: no external component is needed thanks to on-chip integrated capacitors, thus enabling to offer a low BoM solution for end-users and to minimize the PCB area
- Suitable for fast wake-up thanks to a startup time of 200 us, the RC oscillator allows SoCs reaching high performances of wake-up time
- Digital trimming: allows to compensate process errors in order to obtain the nominal frequency
