Grenoble, France - May 22, 2017 - The growing number of battery-powered devices, be they connected or not, which spend most of their time waiting, i.e. in sleep mode, involves to find new solution to lower the power consumption of the always-on power domain. The challenge for SoC designers is indeed to reduce significantly the power consumption in sleep mode, when only the clock and some other triggers are active. A reduction of power consumption of the always-on power domain may easily translate into months and even years of extra usage on the same battery, before its replacement or its recharge.

Dolphin Integration announces today the addition of  ultra-low power 32.768- kHz oscillators dedicated to  always-on power domains, at 55 nm and at 22 nm.

The  qOSC-XTAL-LP-32k-co.02 (crystal-based) and the  qOSC-RC-LP-32k-co.01 (RC-based), benefit from an innovative architecture which combines intrinsically low power consumption - as low as 60 nA – with the capability to safely operate down to near threshold voltage , as low as 0.55 V.

Such ultra-low power oscillators complement the AON silicon IP panoply from Dolphin Integration which may be supplied at any voltage between nominal down to near threshold:  SESAME NTV standard-cell library,  qLR-Aubrey ultra-low quiescent-current voltage regulator and  RTC-32k-CAL.01 Real-Time-Clock.

SoC designers may save up to 80% of power consumption compared to conventional solution during the sleep mode, which represents up to 99.9 % of the use time of an SoC for some IoT and wearable applications!
