The DS1390U-33+TR is a low-voltage Real-Time Clock (RTC) from Analog Devices / Maxim Integrated, designed for applications requiring accurate timekeeping. This device provides hundredths of a second, seconds, minutes, hours, day, date, month, and year information, with automatic adjustments for month lengths and leap years up to 2100.
It features an SPI-compatible interface (supporting modes 0, 1, 2, and 3 depending on the specific variant) or a 3-wire interface for communication. The RTC operates across multiple voltage ranges, including 3.3V ±10%, with specific support for 1.8V ±5% and 3.0V ±10% in other variants. The device is rated for an industrial temperature range of -40°C to +85°C.
Key features include a programmable time-of-day alarm, power-fail detect and switch circuitry, and trickle-charge capability. The output pin can be configured as an interrupt or a square wave with selectable frequencies. The DS1390U-33+TR is available in a 10-pin µSOP package suitable for surface mounting.
Applications for this RTC include hand-held devices, GPS/telematics, embedded time stamping, and medical devices where reliable timekeeping is essential.
