The Analog Devices Inc./Maxim Integrated DS1302ZN is a Real Time Clock (RTC) IC offering a 31-byte clock/calendar with a 3-wire serial interface. This component features leap year compensation and includes NVSRAM for data retention. The trickle-charger functionality supports battery backup. The DS1302ZN operates over a voltage range of 2V to 5.5V, with timekeeping current consumption as low as 0.3µA. It supports both HH:MM:SS (12/24 hr) time format and YY-MM-DD-dd date format. Supplied in an 8-SOIC package (0.154", 3.90mm Width) for surface mounting, this device is suitable for applications requiring accurate timekeeping in industrial, consumer, and communication systems. The operating temperature range is -40°C to 85°C.
