Maxim Integrated DS1501WZN+T&R Product Overview

The DS1501WZN+T&R from Maxim Integrated is a high-precision, full-featured real-time clock (RTC) module that provides a comprehensive timekeeping solution for a wide range of applications. Designed to maintain accurate time and date information, this device integrates a quartz crystal resonator and a temperature-compensated voltage reference, ensuring stability and reliability over varying temperatures and supply voltages.

Key Features

• High Precision: The DS1501WZN+T&R maintains excellent timekeeping accuracy, thanks to its built-in crystal and temperature compensation.
• Y2K Compliance: This RTC is fully compliant with Y2K regulations, featuring a century byte that automatically adjusts for leap years and changes in century.
• Integrated NV SRAM: It includes nonvolatile static RAM, allowing users to store data that must be preserved during power loss without the need for an external battery.
• Watchdog Timer: An integrated watchdog timer enhances system reliability by initiating a system reset in case of a software lock-up or other malfunction.
• Power-Fail Protection: The device features a power-fail circuit that automatically switches to backup power when main power drops below a programmable threshold.
• Trickle-Charge Capability: It supports battery backup with a trickle-charge feature that extends the life of the backup battery.
• Package and Temperature Range: The DS1501WZN+T&R is available in a 28-pin TSOP package and operates over an industrial temperature range.

Applications

The DS1501WZN+T&R is versatile and can be used in various applications, including:

• Networking equipment such as routers and switches
• Industrial systems requiring precise timekeeping
• Data loggers and telemetry systems
• POS terminals and ATMs
• Medical devices that need to log events with a time stamp

With its robust feature set and Maxim Integrated's commitment to quality, the DS1501WZN+T&R is an excellent choice for designers looking to incorporate reliable timekeeping capabilities into their systems.
