Analog Devices Inc./Maxim Integrated DS1302N is a Real Time Clock (RTC) IC offering clock and calendar functionality. This component features a 3-wire serial interface for communication and a 31-byte NVSRAM for data storage. The DS1302N supports both 12 and 24-hour time formats and includes leap year compensation. Its trickle-charger feature allows for battery backup with low current consumption, typically between 0.3µA and 1µA at 2V to 5V. The device operates across a voltage range of 2V to 5.5V, with a battery voltage support also from 2V to 5.5V. The DS1302N is housed in an 8-PDIP package suitable for through-hole mounting. It is commonly utilized in industrial and consumer electronics applications requiring accurate timekeeping. The operating temperature range is -40°C to 85°C.
