The DS1308U-18+ is a low-power I2C real-time clock (RTC) with 56 bytes of non-volatile RAM housed in an 8-pin µSOP package. It features a full binary coded decimal (BCD) clock and calendar, capable of tracking seconds, minutes, hours (in 12 or 24-hour formats with AM/PM indicator), day, date, month, and year. The device automatically adjusts the end-of-month date for months with fewer than 31 days, including leap years. It includes a power-fail detection circuit that switches to backup power to maintain accurate time and date during power failures. Designed for various applications such as office equipment (fax, printers, copiers), telecommunications (routers, switches, servers), utility meters, vending machines, thermostats, and modems. Operating over a voltage range of 1.71V to 5.5V and an temperature range from -40°C to 85°C, it supports crystal ESR up to 100Kohm, optimizing for cost and space. Low power consumption (typical 250nA) ensures extended battery backup time. It features a programmable square wave output, simple serial interface compatible with most microcontrollers, UL recognition, and management of all timekeeping functions with unlimited writes to the RAM.
