Analog Devices Inc./Maxim Integrated DS17485E-5 is a Real Time Clock (RTC) with integrated 4KB of Non-Volatile Static RAM (NVSRAM). This clock/calendar device features a parallel interface and supports both 12/24 hour time formats and YY-MM-DD-dd date formats. Key functionalities include alarms, daylight savings compensation, and leap year calculation. The device operates from a 4.5V to 5.5V supply voltage, with a timekeeping current draw of approximately 3mA at 4.5V. The NVSRAM is powered by a separate battery supply ranging from 2.5V to 3.7V, ensuring data retention during main power loss. The DS17485E-5 is available in a 28-TSSOP package, measuring 0.465 inches (11.80mm) in width, suitable for surface mounting. This component is commonly utilized in industrial control systems, data logging equipment, and telecommunications infrastructure.
