MAXIM INTEGRATED / ANALOG DEVICES DS1394U33 Low-Voltage SPI RTC
The DS1394U-33+ is a low-voltage, SPI-compatible real-time clock (RTC) with a built-in trickle charger, packaged in a 10-pin µSOP package. Operating at a typical voltage of 3.3V, it provides precise timekeeping features including hours, minutes, seconds, hundredths of a second, day, date, month, and year, with automatic date adjustment for months with fewer than 31 days and leap year correction up to 2100. The device supports both 12-hour (AM/PM) and 24-hour formats. It includes a programmable alarm function and monitors the VCC voltage via a temperature-compensated voltage reference, automatically switching to backup power in case of a power failure. The serial interface is SPI compatible, supporting modes 0 and 2, with a maximum SCLK frequency of 4MHz when powered between 2.7V and 5.5V. The RTC operates across a temperature range of -40°C to 85°C, with an active VCC supply current of 2mA, standby current of 115µA, and timekeeping current of 500nA. It is suitable for use in GPS/telematics, embedded timestamping, medical devices, and portable applications. Note that due to market demand, lead times may be extended, and delivery dates can fluctuate. The product is not eligible for discounts.
