Micro Crystal AG’s new Real-time Clock Module RV-3028-C7 sets the new benchmark for lowest power consumption: 40 nA at a supply 3 V.
The high accuracy of ±1 ppm at room temperature eliminates any calibration during manufacturing. The tiny package of just 3.5 x 1.5 x 0.8 mm combines the quartz crystal with the RTC circuit, offering also an integrated battery-back-up switch. The extreme low power consumption allows using MLCC capacitors to cover the back-up time. Together with an event detection input it features all the prerequisites for Wearables, Medical Healthcare and power sensitive IoT applications. http://bit.ly/2GbQVkX
