Analog Devices Inc./Maxim Integrated DS1284Q is a Real Time Clock (RTC) IC offering parallel interface for clock and calendar functions. This component features 50 bytes of battery-backed SRAM for data storage, essential for mission-critical applications. Key functionalities include alarm, leap year compensation, a square wave output, and a watchdog timer, enhancing system reliability. The DS1284Q operates within a voltage range of 4.5V to 5.5V for the main supply and 2.4V to 3.5V for battery backup, with a timekeeping current draw of 7mA at 5V. It supports both 12/24 hour time formats (HH:MM:SS:hh) and YY-MM-DD-dd date formats. Packaged in a 28-PLCC (J-Lead) surface mount configuration, this device is suitable for industrial automation, telecommunications, and medical equipment where accurate timekeeping and data integrity are paramount. The operating temperature range is 0°C to 70°C.
