The DS1305N from Analog Devices is a serial alarm real-time clock (RTC) that manages all timekeeping functions, including seconds, minutes, hours, date, month, day of the week, and year with leap-year compensation valid up to 2100. It features 96 bytes of battery-backed NV RAM for data storage and two programmable time-of-day alarms.
This clock operates with a voltage range of 2.0V to 5.5V and supports SPI (Serial Peripheral Interface) modes 1 and 3, or a standard 3-wire interface. It offers burst mode for reading/writing successive addresses in clock/RAM. The device includes dual-power supply pins for primary and backup power, with an optional trickle charge output to the backup supply.
Packaged in a 16-PDIP through-hole configuration, the DS1305N is designed for applications requiring reliable timekeeping. It supports both 12-hour and 24-hour formats with an AM/PM indicator. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications.
Key features include leap year correction, alarm functionality, and NVSRAM for persistent data storage. The interface logic power-supply pin (VCCIF) allows for easy integration with 3V logic.
