The Analog Devices Inc./Maxim Integrated DS12885N is a Real Time Clock (RTC) and Calendar IC featuring 114B of NVSRAM for timekeeping data retention. This component provides a parallel interface for accessing clock and calendar functions, supporting both HH:MM:SS (12/24 hr) time and YY-MM-DD-dd date formats. Key features include alarm functionality, daylight savings time correction, leap year calculation, and a square wave output. The DS12885N operates within a supply voltage range of 4.5V to 5.5V, with a timekeeping current draw of up to 15mA at 5V. It also supports a battery supply voltage range of 2.5V to 4V for uninterrupted operation. Designed for through-hole mounting, the device is housed in a 24-PDIP package with a 0.600" width. Operating temperatures range from -40°C to 85°C. This component is commonly utilized in industrial control, medical devices, and communication systems.
