Analog Devices Inc./Maxim Integrated DS1302SN is a Real Time Clock (RTC) IC designed for accurate timekeeping. This Clock/Calendar component features a 3-wire serial interface for concise data transfer, supporting both HH:MM:SS (12/24 hr) and YY-MM-DD-dd date formats. With a minimal current draw of 0.3µA to 1µA at 2V to 5V, it is ideal for battery-backed applications. Key functionalities include leap year compensation and trickle-charger support for efficient battery management. The DS1302SN also incorporates 31 bytes of NVSRAM for data retention. Its operating temperature range of -40°C to 85°C makes it suitable for demanding environments. The 8-SOIC (0.209", 5.30mm Width) package with surface mount capability is commonly utilized in industrial control, consumer electronics, and communication systems.
