The Analog Devices Inc./Maxim Integrated DS12R887-33 is a Real Time Clock (RTC) IC featuring a parallel interface and a 48-BBGA package. This clock/calendar component provides accurate timekeeping with a maximum current draw of 2mA at supply voltages between 2.97V and 3.63V. It supports both YY-MM-DD-dd date format and HH:MM:SS (12/24 hr) time formats. Key features include alarm functionality, leap year calculation, integrated NVSRAM, square wave output, and a trickle-charger for battery backup. The device is designed for surface mount applications and operates within a temperature range of -40°C to 85°C. Its 114B memory size and parallel interface make it suitable for applications in industrial control, medical devices, and automotive systems. The supplier device package is a 48-PBGA (11.8x15.3).
