Maxim Integrated DS1672S-3 Low-Voltage Serial Timekeeping Chip

The DS1672S-3 from Maxim Integrated is a highly integrated, low-voltage serial timekeeping chip designed to provide a comprehensive solution for digital timekeeping in a wide range of applications. This compact and efficient device is ideal for systems that require an accurate time base yet have limited space and power resources.

At the heart of the DS1672S-3 is a binary counter that serves as a continuously running clock. The counter increments on the falling edge of the clock input signal, ensuring precise time tracking. The device operates over a voltage range of 2.5V to 5.5V, making it versatile for use in various low-voltage applications, from portable electronics to industrial systems.

One of the key features of the DS1672S-3 is its serial interface, which is compatible with the I²C protocol. This allows for easy integration into existing systems and straightforward communication with microcontrollers and other digital components. The device's serial interface facilitates both reading and writing of the timekeeping registers, giving users full control over the timekeeping functions.

The DS1672S-3 also boasts a robust set of features that enhance its functionality and reliability. It includes an oscillator stop flag that monitors the status of the oscillator and indicates whether it has stopped due to external conditions. This is critical for applications where accurate timekeeping is paramount. Additionally, the device has a programmable trickle charger that enables the connection of a backup energy source, such as a capacitor or rechargeable battery, to maintain timekeeping during power loss situations.

Encased in an 8-pin SO (Small Outline) package, the DS1672S-3 is designed for surface-mount technology, providing a compact footprint that is suitable for space-constrained applications. Its low power consumption and wide operating temperature range of -40°C to +85°C make it a reliable choice for systems that operate in varying environmental conditions.

Overall, the Maxim Integrated DS1672S-3 is a versatile and reliable component for maintaining accurate time in your digital systems, offering a seamless blend of performance, integration, and energy efficiency.
