The Analog Devices Inc./Maxim Integrated DS1302S-T-R is a real-time clock (RTC) IC that provides a comprehensive clock/calendar function with a 31-byte NVSRAM for data storage. This component features a 3-wire serial interface for efficient communication, supporting both 12-hour and 24-hour time formats, and a YY-MM-DD-dd date format. Key functionalities include leap year compensation and a trickle-charge pin for maintaining battery power. Designed for surface mounting in an 8-SOIC package, the DS1302S-T-R operates across a voltage range of 2V to 5.5V, with timekeeping current drawing a minimal 0.3µA to 1µA. This device is commonly utilized in industrial control systems, medical devices, and consumer electronics where accurate timekeeping is critical. The component is supplied in a Tape & Reel (TR) package.
