Introducing the DS1687-5 Real-Time Clock from Maxim Integrated

The DS1687-5 is a high-precision, full-featured real-time clock (RTC) module that offers a wide range of functionalities suitable for various time-critical applications. Designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products, the DS1687-5 is built to ensure reliability and accuracy in timekeeping.

This RTC module comes with an integrated crystal oscillator and a lithium battery, which guarantees long-term data retention and an accurate timekeeping system, even when the main power supply is turned off. The DS1687-5 operates over a temperature range of 0°C to +70°C, making it versatile for use in a variety of environments.

One of the key features of the DS1687-5 is its compliance with the industry-standard JEDEC footprint, which simplifies the integration process into existing designs. It is housed in a 24-pin EDIP or LCC package, ensuring easy mounting on a variety of PCB layouts.

Core Features:

• Integrated Power-Supply: Comes with a long-life lithium battery that ensures up to 10 years of data retention and timekeeping in the absence of external power.
• Timekeeping Accuracy: Maintains time with precision due to its onboard crystal oscillator, which minimizes time drift.
• Memory: Features 114 bytes of NV SRAM, which can be used to store data that must be preserved during power loss.
• Programmable Alarm: Includes an alarm function that can be set to trigger on a specific date, day of the week, hour, minute, and second.
• Interfacing: Offers a simple multiplexed byte-wide interface, which allows for easy communication with microprocessors.
• Countdown Timer: Features a countdown timer with an interrupt output, providing additional timing capabilities.

With its robust feature set, the DS1687-5 is an ideal choice for applications requiring precise time management, such as data loggers, industrial systems, embedded computers, and other electronic devices that require a reliable time base. Maxim Integrated's commitment to quality ensures that the DS1687-5 RTC module delivers consistent performance and durability for critical applications where time accuracy is paramount.
