Maxim Integrated DS1672U-33+T Real-Time Clock

The DS1672U-33+T from Maxim Integrated is a robust and highly integrated Real-Time Clock (RTC) designed to provide precise time and date information for a wide range of applications. This compact RTC module operates over a wide voltage range and is encapsulated in a space-saving 8-pin μSOP package, making it an ideal choice for systems where board space is at a premium.

The DS1672U-33+T is characterized by its low power consumption, which makes it suitable for battery-powered devices where power efficiency is crucial. It operates from a supply voltage of 2.5V to 5.5V, allowing it to be used in both 3.3V and 5V systems. The device also features a built-in power-sense circuit that detects power failures and automatically switches to the backup battery, ensuring uninterrupted timekeeping.

One of the key features of the DS1672U-33+T is its serial interface, which enables easy communication with microcontrollers or other digital systems. The RTC provides a simple I2C-compatible serial interface, allowing for straightforward integration into existing designs without the need for complex wiring or additional components.

The device offers a full calendar clock that includes seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation valid up to the year 2100. The accuracy of the clock is maintained within ±1 minute per month at room temperature, which is more than sufficient for most applications.

Additionally, the DS1672U-33+T features a programmable time-of-day alarm and a programmable square-wave output, giving designers the flexibility to implement various time-related functions in their applications. These features are particularly useful for scheduled events and periodic system wake-ups.

Overall, the Maxim Integrated DS1672U-33+T is a versatile and reliable RTC solution that offers high performance, low power consumption, and easy integration, making it an excellent choice for embedded systems, consumer electronics, portable devices, and any other application requiring accurate timekeeping.
