Analog Devices Inc./Maxim Integrated DS14285QN is a Real Time Clock (RTC) IC featuring a parallel interface and a 114B internal NVSRAM. This clock/calendar component supports both 12/24 hour time formats and YY-MM-DD-dd date formats, with advanced features including alarm functionality, daylight saving time compensation, leap year calculation, and a square wave output. The device operates within a voltage range of 4.5V to 5.5V for the main supply and 2.5V to 3.6V for battery backup, maintaining timekeeping accuracy with a maximum current draw of 0.5µA at 5V. Designed for surface mounting, it is housed in a 28-PLCC package. The DS14285QN is suitable for applications requiring precise timekeeping and historical data logging, often found in industrial control, data acquisition, and telecommunications equipment. It operates across a temperature range of -40°C to 85°C.
