Maxim Integrated DS1250YP-70 Nonvolatile Memory

The DS1250YP-70 from Maxim Integrated is a robust, high-quality nonvolatile memory module designed to retain data for an extended period without the need for a power supply. This 5V, 4096k NV SRAM with a Phantom Clock is an ideal solution for a wide range of applications that require data security and integrity, even in the event of a power failure.

Key Features

• High Capacity: The DS1250YP-70 offers a substantial 4 Mbit (512k x 8) of memory space, allowing for the storage of significant amounts of data.
• Nonvolatile SRAM: The device includes a self-contained lithium energy source and control circuitry which constantly monitors V<sub>CC for an out-of-tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption.
• Integrated Real-Time Clock: The Phantom Clock provides timekeeping functionality, making this memory module a comprehensive solution for time-stamped data logging or other time-sensitive applications.
• Fast Access Time: With access times as fast as 70ns, the DS1250YP-70 facilitates rapid data retrieval, ensuring efficient system performance.
• Durable: Housed in a rugged 28-pin EDIP or 32-pin TSOP package, the DS1250YP-70 is designed to withstand harsh environments and provide reliable performance over a wide temperature range.
• Long Battery Life: The onboard battery reliably maintains data and real-time clock operation for over 10 years, ensuring long-term data retention.
• Easy to Integrate: With a JEDEC standard pinout, integration into existing systems is straightforward, minimizing design complexities and time to market.

Applications

The DS1250YP-70 is suitable for a variety of applications, including industrial control systems, utility meters, POS terminals, and medical devices. Its nonvolatility and integrated clock make it particularly well-suited for critical data logging, time-stamped event recording, and applications requiring data preservation during power loss.

Maxim Integrated's commitment to quality ensures that the DS1250YP-70 provides reliable data retention and protection, making it a trusted choice for designers and engineers looking for a secure and durable nonvolatile memory solution.
