Maxim Integrated DS1672-33+ Low-Voltage Serial Timekeeping Chip

The DS1672-33+ from Maxim Integrated is a robust, low-voltage serial timekeeping chip that provides a full binary-coded decimal (BCD) clock/calendar with 31 bytes of static RAM. This innovative component is designed to maintain accurate timekeeping when the main power to the device is turned off. As a non-volatile timekeeping solution, it is an ideal choice for a wide range of applications such as embedded systems, utility meters, and portable devices where maintaining accurate time is critical.

Operating at a voltage range of 2.5V to 5.5V, the DS1672-33+ is versatile and can be easily integrated into systems with varying power supplies. The timekeeping function includes seconds, minutes, hours, day, date, month, and year information with leap-year compensation up to the year 2100. This ensures long-term reliability and accuracy of the timekeeping functionality without the need for manual adjustments or software compensation.

The DS1672-33+ communicates with the host system through an I²C serial interface, which simplifies the integration process and allows for easy communication with most microcontrollers. Furthermore, the device features a built-in oscillator that eliminates the need for external timing components, thus reducing the overall bill of materials and simplifying the design process.

The device's static RAM can be used to store data that must be preserved during power loss events. This makes the DS1672-33+ an excellent choice for applications that require data logging or storage of critical system parameters. Its compact SOP-8 packaging makes it suitable for space-constrained applications, and the surface-mount design allows for streamlined manufacturing processes.

Maxim Integrated's commitment to quality ensures that the DS1672-33+ meets the high standards required for modern electronic devices. With its combination of accurate timekeeping, low-voltage operation, and convenient communication interface, the DS1672-33+ is a reliable solution for designers looking to incorporate a trusted timekeeping component into their systems.
