Analog Devices Inc./Maxim Integrated DS1556WP-120 is a Real Time Clock (RTC) with an integrated 128KB NVSRAM. This Clock/Calendar component features a parallel interface and operates within a 2.97V to 3.63V supply voltage range, with a 3V battery backup. Key functionalities include alarm, leap year calculation, and a watchdog timer, along with Y2K compliance. The device offers both 24-hour time format (HH:MM:SS) and YY-MM-DD-dd date format. Designed for surface mounting, it is housed in a 34-PowerCap™ Module package and operates across a temperature range of 0°C to 70°C. Typical applications include industrial control systems, telecommunications equipment, and consumer electronics requiring accurate timekeeping and non-volatile data storage. The timekeeping current consumption is a maximum of 4mA at 3.3V.
