The Analog Devices Inc./Maxim Integrated DS1305E is a Clock/Calendar Real Time Clock (RTC) IC. This component offers a 96-byte NVSRAM for data storage, featuring alarm functionality and leap year compensation. Its SPI interface facilitates communication, and it supports both 12/24 hour time formats and a YY-MM-DD-dd date format. The DS1305E operates within a voltage range of 2V to 5.5V for both supply and battery inputs, with timekeeping current consumption ranging from 25.3µA to 81µA. Key features include a trickle-charger input for backup power management. Packaged in a 20-TSSOP (0.173", 4.40mm Width) for surface mounting, this device is suitable for applications in industrial automation, consumer electronics, and telecommunications. The operating temperature range is 0°C to 70°C.
