Real-Time Clock (RTC) Modules

Micro Crystal Real-Time Clock (RTC) Modules combine a 32.768kHz tuning fork crystal resonator with a CMOS-based oscillator and an RTC IC housed in a miniature SMD ceramic package. The RTC modules offer high accuracy, temperature compensation, and low current consumption. These cost-effective Micro Crystal modules have an extended operating temperature and are AEC-Q200 qualified. Applications include the Internet of Things (IoT), smart metering, energy harvesting solutions, battery management systems, automotive, industrial, computing, embedded systems, wearables, healthcare, and more.
