The DS1338U-3 is a low-power, serial real-time clock (RTC) and calendar IC from Analog Devices / Maxim Integrated. It provides full binary-coded decimal (BCD) clock/calendar functions along with 56 bytes of non-volatile SRAM. Data is transferred serially via an I2C interface.
This device manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. It supports both 24-hour and 12-hour formats with an AM/PM indicator. The integrated power-sense circuit automatically switches to a backup supply during power failures, ensuring continuous time and date operation.
The DS1338U-3 features a programmable square-wave output signal and operates within an industrial temperature range of -40°C to +85°C. It is available in a compact 8-uMAX/uSOP surface-mount package, making it suitable for space-constrained applications.
Key applications include handheld devices, consumer electronics, office equipment, medical devices, and telecommunications infrastructure.
The operating voltage range is 1.3V to 3.7V.
The operating temperature range is -40°C to 85°C.
The DS1338U-3 is available in an 8-uMAX/uSOP surface-mount package.
