The DS1390U-18+ from Analog Devices / Maxim Integrated is a low-voltage SPI real-time clock (RTC) that provides timekeeping information including hundredths of seconds, seconds, minutes, hours, day, date, month, and year with leap-year compensation valid up to 2100. It features a programmable time-of-day alarm and power-fail detect circuitry.
This clock operates over an industrial temperature range of -40°C to +85°C and supports a wide voltage range from 1.3V to 3.7V. The interface is SPI compatible, and the device consumes a maximum of 100µA at 1.71V to 1.89V. It offers features such as a square wave output with programmable frequencies and trickle-charge capability.
The DS1390U-18+ is available in a compact 10-pin uMAX/uSOP package, suitable for surface mount applications. The date and time formats are configurable, supporting both YY-MM-DD-dd and HH:MM:SS:hh (12/24 hr) respectively.
The operating voltage range is 1.3V to 3.7V.
The operating temperature range is -40°C to 85°C.
