Maxim Integrated DS1687-5IND Real-Time Clock

The Maxim Integrated DS1687-5IND is a robust, full-featured real-time clock (RTC) module designed to provide precise time and date information for industrial applications. This high-reliability device integrates a battery-backed nonvolatile (NV) timekeeping RAM, which ensures that timekeeping operations continue uninterrupted in the event of a power failure.

The DS1687-5IND is specifically tailored for demanding environments, with an industrial temperature range of -40°C to +85°C, making it suitable for a wide array of applications, including factory automation, process control systems, and ruggedized computing platforms.

Key features of the DS1687-5IND include:

• A built-in crystal oscillator with a frequency of 32.768 kHz, ensuring high accuracy in timekeeping.
• A programmable periodic or square wave output that can be used for various timing functions.
• A generous 114 bytes of NV SRAM, which can be used to store data that must be preserved during power loss.
• An integrated lithium energy source that provides years of autonomous operation, maintaining time and date data for the life of the product.
• Timekeeping functions that include seconds, minutes, hours, day, date, month, and year information, with automatic adjustments for months with fewer than 31 days and leap year compensation valid up to the year 2100.
• A set of time-of-day alarms, which can be programmed to trigger on a per-second, per-minute, per-hour, or daily basis, providing versatile alerting capabilities.
• Multiple power-saving modes, including a disable clock option to minimize current consumption during periods of inactivity.

With its combination of durability, precision, and feature-rich design, the DS1687-5IND from Maxim Integrated is an ideal choice for system designers who require a reliable and flexible RTC solution for industrial-grade applications. Its longevity and performance under extreme conditions make it a standout component in the realm of timekeeping technology.

Manufacturers and developers seeking to integrate a dependable RTC into their systems will find the DS1687-5IND to be a versatile and practical component that meets their stringent requirements.
