Abracon AB-RTC-TN Real-Time Clocks (RTCs)
Abracon AB-RTC-TN Real-Time Clocks (RTCs) with integrated Temperature-Compensated Crystal Oscillator (TCXO) deliver ±3ppm stability across a wide temperature range, ensuring precise timekeeping for demanding applications. Integrating the RTC and oscillator into a single compact module reduces frequency drift, minimizes external components, and simplifies system design while enhancing reliability. The AB-RTC-TN RTCs feature ultra-low power consumption of 240nA and an automotive-grade option, supporting long-life, battery-operated devices and ensuring uninterrupted timekeeping even during power failures. The AB-RTC-TN RTCs are suited for smart-metering, automotive event data recorders, UAVs, SCADA systems, medical devices, and surveillance equipment.
