MAXIM INTEGRATED / ANALOG DEVICES DS1340Z18 Real-Time Clock Module
The DS1340Z-18+ is an I2C real-time clock (RTC) with a built-in trickle charger, housed in an 8-pin NSOIC package. It offers trickle-charge functionality on the VBACKUP pin, supports a lower timekeeping voltage, and includes an oscillator stop flag. The device maintains its compatibility with the ST M41T00, including identical register maps and software clock calibration, with two additional registers for managing the trickle charger and flag. It provides full timekeeping functions, including seconds, minutes, hours, day, date, month, and year. A power-sense circuit detects power failures and automatically switches to backup power to ensure continuous operation. All read and write operations are serially programmed via a bi-directional I2C bus. Suitable applications include point of sale systems, telecommunications, portable devices, and medical equipment.
