1 pcs : RV-3028-C7 ON BOARD 32.768kHz TA QC - Clock & Timer Development Tools 32.768kHz I2C Time Acc. 1ppm

RV-3028-C7 Real-Time Clock (RTC) Modules Micro Crystal RV-3028-C7 Real-Time Clock (RTC) Modules provides low power consumption of 45nA at a supply of 3V and ±1ppm accuracy at room temperature. These features eliminate any calibration during manufacturing. The miniature SMD ceramic package (3.2mm x 1.5mm x 0.8mm) includes the 32.768kHz quartz crystal as part of a hermetically sealed module. The extremely low power consumption combined with the integrated battery backup switch with trickle charger allows for the use of MLCC capacitors/Supercaps to provide extended back‐up time. Together with an event detection input, the RV-3028-C7 modules feature all the prerequisites for Wearables, Medical Healthcare, and other power-sensitive IoT applications.
