Description

Maxim Integrated DS1501WS Y2K-Compliant Watchdog Real-Time Clock

The Maxim Integrated DS1501WS is a full-featured, Y2K-compliant real-time clock (RTC) with an integrated watchdog timer, alarm, and century byte. Designed with precision and reliability in mind, it is targeted towards systems that require accurate timekeeping, scheduled operations, and system monitoring to prevent lockups. Encapsulated in a durable surface-mount package, it is ideal for embedded systems, servers, networking equipment, and other time-sensitive applications.

Key Features:

  • Y2K Compliance: The DS1501WS is fully prepared to handle the transition from December 31, 1999, to January 1, 2000, and beyond, thanks to its century byte and date logic.
  • Watchdog Timer: A crucial feature for system stability, the integrated watchdog timer helps to recover from runaway or locked-up code by resetting the system if the timer is not periodically cleared.
  • Alarm Function: The alarm can be set to trigger on a per-second, per-minute, per-hour, or daily basis, providing versatility for various timed events and operations.
  • High Precision: The device maintains accurate timekeeping with a precision oscillator and supports leap year compensation up to the year 2100.
  • Power Management: The DS1501WS includes a power-fail circuit that automatically switches to backup battery power when the main power supply fails, ensuring uninterrupted timekeeping.
  • Memory: The device features a serial real-time clock with 114 bytes of NV SRAM, offering storage for critical data that must be preserved during power loss.
  • Interface: It communicates with the host system via a simple serial interface compatible with most microcontrollers.
  • Durability: The surface-mount package ensures a robust and reliable integration into a variety of hardware configurations.

The DS1501WS from Maxim Integrated is a versatile and dependable choice for systems requiring accurate real-time clocks with additional watchdog and alarm functionality. Its Y2K readiness and integrated features make it a smart solution for maintaining system integrity and performance.
