Maxim Integrated DS1672U-33 Low-Voltage Serial Timekeeping Chip

The Maxim Integrated DS1672U-33 is a state-of-the-art, low-voltage serial timekeeping chip that offers a full binary-coded decimal (BCD) clock/calendar with 56 bytes of NV SRAM. This compact and efficient device is designed to provide precise time and date tracking, along with a memory component, all in a single package. It's an ideal solution for applications that require reliable timekeeping under low-power conditions.

This versatile chip features a serial interface that allows it to communicate with a microprocessor over a simple, 3-wire bus. The DS1672U-33 operates on a wide voltage range from 2.5V to 5.5V, making it suitable for use in various systems, including those powered by battery or those undergoing power fluctuations. Its low power consumption ensures minimal impact on the system's battery life, an essential aspect for portable and remote applications.

The DS1672U-33 incorporates a real-time clock/calendar that tracks time in hours, minutes, and seconds, and the date in terms of the day, month, and year. The clock/calendar functionality automatically adjusts for months with fewer than 31 days, including corrections for leap year. The integrated 56 bytes of NV SRAM provide scratchpad memory, which can be used to store data that must be preserved during power loss events, enhancing the reliability of the system it is incorporated into.

Encased in an 8-pin μSOP package, the DS1672U-33 is designed with a built-in oscillator that uses an external, low-cost 32.768kHz crystal. This precision timekeeping is further ensured by the oscillator's low drift characteristics, which contribute to the chip's overall accuracy.

With its comprehensive feature set and robust design, the Maxim Integrated DS1672U-33 is an excellent choice for a wide range of applications, including portable devices, data loggers, and other systems that require accurate timekeeping and data storage without compromising on power efficiency.

For developers and manufacturers, the DS1672U-33 offers a seamless integration path, thanks to its industry-standard packaging and interface, making it a reliable and convenient component for enhancing product capabilities.
