The Analog Devices Inc./Maxim Integrated DS1284QN-T-R is a Clock/Calendar Real Time Clock (RTC) IC. This component features a 50-byte parallel interface for data access and a 28-PLCC package for surface mounting. It provides essential timekeeping functions including clock and calendar operations with support for both 12 and 24-hour formats, and a YY-MM-DD-dd date format. Key features include alarm functionality, leap year compensation, a square wave output, integrated SRAM, and a watchdog timer. Operating within a supply voltage range of 4.5V to 5.5V, it offers a timekeeping current consumption of up to 7mA at 5V and is designed for battery backup operation with a 2.4V to 3.5V range. The device operates across an industrial temperature range of -40°C to 85°C. This component is typically utilized in applications requiring accurate timekeeping and calendar functions, such as industrial control systems and data logging equipment. The DS1284QN-T-R is supplied in Tape & Reel packaging.
