Real-Time Clock (RTC) and calendar.
Our broad assortment of tiny, full-featured, real-time clocks delivers high accuracy and low power consumption to a variety of end applications. From battery management and alarm to time-stamp and tamper detect functionality—our RTCs offer a wide range of features for your system. Automotive compliant AEC-Q100 devices are also available.
Ultra-Low-Power RTCs provide the low power consumption that enables long battery life with regard to real-time clock functionality. Energy-efficient devices are available with I2C or SPI bus interfaces.
Temperature Compensated with Integrated Crystal CMOS RTCs are optimized for very high accuracy and low power consumption for industrial applications. The devices sense temperature and make internal adjustments to ensure accurate time keeping over temperature range. Available with pin-selectable I²C bus or SPI bus.
AEC-Q100 Qualified RTCs are designed for highest reliability and lowest power consumption and are available with I2C or SPI bus interfaces. They have an extended operating temperature range of up to 125º C and AEC-Q100 automotive-compliant qualification.
