Micro Crystal RV-3028-C7 Real-Time Clock (RTC) Modules
Micro Crystal RV-3028-C7 Real-Time Clock (RTC) Modules provide 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 MLCC capacitors/Supercaps to provide extended backup time. With an event detection input, the RV-3028-C7 modules from Micro Crystals feature all the prerequisites for wearables, medical healthcare, and other power-sensitive IoT applications.
