Maxim Integrated DS1343D-33+T&R Real-Time Clock

The DS1343D-33+T&R from Maxim Integrated is a high-precision, low-power real-time clock (RTC) with a built-in temperature-compensated crystal oscillator (TCXO) and crystal. This RTC is designed to provide accurate timekeeping with minimal power consumption, making it an ideal choice for battery-powered applications or systems where maintaining precise time is crucial.

Featuring an I2C serial interface for easy integration into a wide range of systems, the DS1343D-33+T&R offers a full binary-coded decimal (BCD) clock/calendar with 56 bytes of NV SRAM. This additional memory space can be used to store data that must be preserved during power loss events, ensuring the integrity and recovery of critical information.

The device operates over the standard industrial temperature range of -40°C to +85°C, providing reliable performance in harsh environments. The DS1343D-33+T&R is also designed with an automatic backup switching circuitry that allows it to seamlessly transition to backup power when the primary power source fails, without any interruption to the clock function.

Key features of the DS1343D-33+T&R include:

• Accurate timekeeping with a temperature-compensated crystal oscillator.
• Low power consumption suitable for battery-operated devices.
• 56 bytes of non-volatile SRAM for data storage.
• I2C serial interface for straightforward system integration.
• Automatic backup power switching to maintain timekeeping during power failures.
• Industrial temperature range compatibility.

The DS1343D-33+T&R is available in a compact, surface-mount package and is supplied on tape and reel (T&R) for automated assembly processes. This makes it an excellent choice for mass production environments where efficiency and reliability are key concerns.

Whether you are designing consumer electronics, industrial control systems, or portable medical devices, the Maxim Integrated DS1343D-33+T&R provides a robust and reliable timekeeping solution that can help to ensure the accuracy and stability of your system's time-related functions.
