The 1337GNLGI is a low power real-time clock (RTC) from Quarktwin Technology Ltd. designed for applications requiring accurate timekeeping. It features a 16-pin QFN package and operates within a voltage range of 1.8 to 5.5 V. The device supports an I2C serial interface, allowing for easy integration into various systems. It provides comprehensive timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with automatic adjustments for months with fewer than 31 days and leap years valid up to the year 2100. The RTC includes two programmable time-of-day alarms and a programmable square-wave output, which defaults to 32 kHz upon power-up. It is suitable for a wide range of applications, including telecommunications, handheld devices, medical equipment, and office machinery. The operating temperature range is from -40 to +85¬8C, with an extended range of -40 to +105¬8C available for specific package types. The device is RoHS compliant, ensuring it meets environmental standards.
