Maxim Integrated DS1251W-120IND+ Nonvolatile Timekeeping RAM

The DS1251W-120IND+ is a high-performance, 2M x 8 nonvolatile timekeeping RAM module from Maxim Integrated that combines a full-featured, battery-backed real-time clock/calendar (RTC) and a 2M x 8 NV SRAM in one integrated package. Designed for applications that demand the reliability and long-term data retention of nonvolatile memory, along with an integrated timekeeping function, this product is ideal for industrial, automotive, and other systems requiring robust performance in harsh environments.

Key Features

• Nonvolatile Timekeeping: Time, date, and control registers are fully backed by a nonvolatile (NV) controller circuit, ensuring data retention and accurate timekeeping during power outages without the need for an external battery.
• High-Speed NV SRAM: The 2M x 8 static RAM offers fast access times, providing high-speed data transfer and storage.
• Industrial Temperature Range: The DS1251W-120IND+ is designed to operate reliably over an industrial temperature range of -40°C to +85°C, making it suitable for challenging conditions.
• Automatic Battery Switchover: In the event of a power failure, the device automatically switches to the backup energy source to maintain timekeeping and SRAM data.
• Long Battery Life: The low energy consumption design extends the life of the backup battery, reducing maintenance frequency and costs.
• Surface-Mount Package: The module comes in a 32-pin encapsulated module, ensuring easy integration into surface-mount technology (SMT) manufacturing processes.
• Integrated Crystal: The inclusion of a precision crystal oscillator eliminates the need for external timing components, simplifying design and reducing board space requirements.

Applications

The DS1251W-120IND+ is suitable for a wide range of applications, including:

• Industrial control systems
• Automotive systems
• Telecommunication infrastructure
• Networking equipment
• Embedded systems

With its robust design and integrated features, the DS1251W-120IND+ from Maxim Integrated is a reliable choice for systems that require durable nonvolatile memory with an embedded real-time clock.
