The DS1746P-70+ is a highly integrated, full-featured memory module from Maxim Integrated that combines a full-function real-time clock, 512kb NV SRAM, power-fail control circuit, and battery in a single 34-pin DIP package. This product is designed to provide a reliable, long-term, non-volatile memory solution with a built-in timekeeping function, which is particularly suitable for applications that require data and time to be continuously maintained in the absence of an external power supply.

Key Features

• Real-Time Clock (RTC): The DS1746P-70+ includes a highly accurate RTC with a crystal oscillator, which ensures precise timekeeping. It provides year, month, day, date, hours, minutes, and seconds information and has automatic leap year compensation valid up to the year 2100.
• Non-Volatile SRAM: With its 512kb non-volatile static RAM, this module preserves data integrity by automatically switching to battery backup mode during power failures, ensuring that data is retained.
• Integrated Battery: The onboard lithium battery has a long shelf life and operational life, providing years of maintenance-free operation and data retention without the need for an external battery.
• Power-Fail Control: The DS1746P-70+ features a power-fail control circuit that guarantees a safe transition to battery backup mode, providing a robust solution for power-sensitive systems.
• Accessible Memory: The NV SRAM is directly accessible in the same manner as a conventional SRAM, making it easy to integrate into various systems without the need for complex programming.

Applications

The DS1746P-70+ is an ideal memory and real-time clock solution for a wide range of applications, including:

• Telecommunication systems
• Embedded systems
• Industrial control systems
• Network servers
• Medical devices
• POS terminals

With its combination of durability, precision, and ease of use, the DS1746P-70+ from Maxim Integrated is a top choice for designers looking to enhance their systems with a reliable time and data storage solution.
