Maxim Integrated DS1220Y-200IND+ Nonvolatile SRAM

The Maxim Integrated DS1220Y-200IND+ is a high-performance, 16k Nonvolatile SRAM designed to provide a reliable and durable memory solution for industrial and critical applications where data persistence is paramount. This innovative component combines the access speed of static RAM with a non-volatile storage capability, ensuring that data is preserved even when the power supply is interrupted.

Featuring a 2k x 8 memory configuration, the DS1220Y-200IND+ offers a substantial amount of storage for system configuration, data logging, or any other application that requires quick access to stored data without the risk of data loss. The integrated lithium energy source and control circuitry constantly monitor VCC 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 during the power loss.

This particular model, designed for industrial applications, comes with an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments where standard components may fail. The DS1220Y-200IND+ is also packaged in a robust 24-pin EDIP (Encapsulated Dual In-line Package), ensuring physical durability and ease of integration into a wide range of systems.

Key features of the DS1220Y-200IND+ include:

• 10 years minimum data retention in the absence of external power
• Data is automatically protected during power loss
• Unlimited write cycles, providing the high endurance required by frequent data updates
• Fast read and write access times of 200ns, enabling efficient system performance
• Directly replaces volatile static RAM or EEPROM
• Integrated battery with a lifespan that typically exceeds the life of the system

The DS1220Y-200IND+ is an ideal memory solution for a wide range of applications, including industrial control systems, utility meters, medical devices, and any other system where the integrity of stored data is critical. With its robust design and integrated power-fail protection, the Maxim Integrated DS1220Y-200IND+ ensures that your data remains safe and accessible, even under the most challenging conditions.
