The Analog Devices Inc./Maxim Integrated DS12885T-T-R is a Real Time Clock (RTC) IC designed for precise timekeeping. This clock/calendar component features an 114-byte NV SRAM for data storage and an 8-bit parallel interface for efficient data transfer. Key functionalities include alarm capabilities, daylight saving time adjustments, and leap year compensation, ensuring accurate chronological tracking. The device supports both 12-hour and 24-hour time formats, along with a YY-MM-DD-dd date format. Operating within a supply voltage range of 4.5V to 5.5V, it also accommodates a battery voltage from 2.5V to 4V for continuous operation. Packaged in a 32-TQFP (7x7) surface-mount form factor, the DS12885T-T-R is suitable for applications requiring robust timekeeping in industrial, consumer electronics, and telecommunications sectors. The component operates at a maximum current of 15mA at 4.5V.
