Maxim Integrated DS1554WP-120+ Overview

The DS1554WP-120+ from Maxim Integrated is a robust, full-function, year 2000-compliant (Y2K) real-time clock/calendar (RTC) with an integrated 512k NV SRAM. This high-performance component is designed to provide a reliable timing solution with the added benefit of non-volatile memory storage, making it an ideal choice for a wide range of applications that require data preservation during power loss.

Key Features

• Real-Time Clock/Calendar: Tracks time in hours, minutes, and seconds. The calendar functionality accounts for days, weeks, months, and years, including corrections for leap years up to the year 2100.
• Non-Volatile SRAM: The device includes 512k of non-volatile SRAM, providing data retention without the need for a battery backup during power failures.
• Integrated Power-Fail Detect: Features a built-in power-fail circuit that automatically switches to the backup energy source when a power failure is detected, ensuring uninterrupted operation of the timekeeping functions.
• Lithium Energy Source: Comes with a long-life, replaceable lithium battery, which ensures data and time retention for the rated life of the battery.
• Watchdog Timer: The integrated watchdog timer can be programmed to reset a hung system and ensure proper operation.
• Surface-Mount Package: The DS1554WP-120+ is available in a water-washable, 34-pin PowerCap Module (PCM) surface-mount package that is highly resistant to environmental factors.
• Industrial Temperature Range: Operates effectively across an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.

Applications

The versatility of the DS1554WP-120+ makes it an excellent choice for a variety of applications, including:

• Embedded systems
• Utility meters
• POS terminals
• Industrial timekeeping
• Network servers
• Medical devices
