Maxim Integrated DS1314S+T&R Nonvolatile Timekeeping RAM

The DS1314S+T&R from Maxim Integrated is a state-of-the-art nonvolatile timekeeping RAM that seamlessly combines the functionality of a real-time clock (RTC) with a fully integrated NV SRAM and a sophisticated power-monitoring circuitry. This unique product is designed to maintain accurate time and date information, along with providing a reliable nonvolatile memory storage solution that preserves data in the absence of power.

The device is particularly suited for applications that require robust timekeeping and data retention capabilities without the need for an external battery. Its innovative design ensures that all data is automatically transferred from the SRAM to the nonvolatile memory when a power failure is detected and then back to the SRAM when power is restored, providing a fail-safe storage environment.

Key Features

• Integrated Real-Time Clock: The DS1314S+T&R features a highly accurate RTC that provides year, month, day, date, hours, minutes, and seconds based on a 32.768 kHz crystal oscillator.
• Automatic Nonvolatile Operation: With its automatic power-fail chip deselect and write-protection features, the device ensures that data is protected during power loss without any user intervention.
• Trickle Charge Capability: The onboard trickle charge circuit allows for an external capacitor or battery to be connected, ensuring the RTC remains powered during extended power outages.
• Surface-Mount Package: The DS1314S+T&R is available in a surface-mount package, making it ideal for compact and high-density applications.
• High Reliability: With its robust design, the product guarantees data retention and clock functionality for over 10 years in the absence of power.

Applications

The DS1314S+T&R is versatile and can be used in a wide range of applications where reliable timekeeping and data retention are critical. This includes but is not limited to:

• Embedded systems
• Utility meters
• Industrial timekeeping
• POS terminals
• Medical devices
• Security systems

With its combination of durability, precision, and ease of integration, the DS1314S+T&R from Maxim Integrated is an excellent choice for designers looking to add nonvolatile timekeeping and memory capabilities to their systems.
