The DS1340U-33+T is a highly integrated, low-power real-time clock (RTC) from Maxim Integrated, designed to provide precise time and date information for a wide range of applications. This RTC is particularly well-suited for systems that require reliable timekeeping, such as data loggers, industrial controllers, and smart meters.

Operating at a voltage of 3.3V, the DS1340U-33+T is optimized for applications that need to maintain low power consumption. Its timekeeping functions include seconds, minutes, hours, day, date, month, and year information, with the added convenience of automatic leap year compensation valid up to the year 2100.

One of the standout features of this device is its integrated trickle-charge capability. This allows the RTC to maintain timekeeping operations by charging a backup battery or supercapacitor during normal operation, ensuring that time is kept even during power outages or when the main power supply is disconnected.

The DS1340U-33+T communicates over a simple I²C interface, making it easy to integrate into existing designs. It also features a robust crystal oscillator, which serves as the timekeeping element, providing long-term accuracy and stability. In addition, the device includes two programmable time-of-day alarms and a programmable square-wave output, offering added flexibility for system designers.

Packaged in a compact 8-pin µSOP, the DS1340U-33+T is designed to occupy minimal board space, making it an excellent choice for space-constrained applications. Its surface-mount package type allows for efficient assembly in high-volume production environments.

Maxim Integrated's commitment to quality ensures that the DS1340U-33+T meets the highest standards of reliability and performance. With its combination of features, low power consumption, and small footprint, this RTC is an ideal choice for designers looking to add accurate timekeeping functionality to their next project.
