Quality Control: Learn More
The Analog Devices Inc./Maxim Integrated DS1338Z-33 is a Real-Time Clock (RTC) IC designed for accurate timekeeping and calendar functions. This component features a 56-byte NVSRAM for data storage and offers a 2-wire serial interface, compatible with I2C protocols. Operating within a supply voltage range of 3V to 5.5V, it draws a maximum of 200µA at 5.5V for timekeeping. The device supports both 12/24 hour time formats and a YY-MM-DD-dd date format, including leap year compensation. Additional features include a square wave output. Housed in an 8-SOIC (0.154", 3.90mm width) surface mount package, the DS1338Z-33 is suitable for applications requiring robust timekeeping, such as industrial automation, consumer electronics, and telecommunications systems. Its operating temperature range is -40°C to 85°C.
