The 1339AC-31SRGI is a low-power real-time clock (RTC) from Quarktwin Technology Ltd. designed for precise timekeeping and date management. It features a serial I¬=C interface for data communication and provides comprehensive time/date information, including seconds, minutes, hours, day, date, month, and year, with automatic adjustments for months with fewer than 31 days and leap years up to the year 2100. The device supports both 12-hour and 24-hour formats with an AM/PM indicator. This RTC includes two programmable time-of-day alarms and a programmable square-wave output. It is equipped with a power-sense circuit that detects power failures, automatically switching to a backup supply to maintain time and alarm functionality. The 1339AC-31SRGI operates within an industrial temperature range of -40¬8C to +85¬8C and is available in a 16-SOIC package. It is UL recognized and includes a trickle-charge capability for backup power sources. This product is suitable for various applications, including handheld devices, consumer electronics, office equipment, medical devices, and telecommunications.
