Maxim Integrated DS1230AB-200IND Nonvolatile SRAM

The Maxim Integrated DS1230AB-200IND is a high-performance, 256k Nonvolatile SRAM memory chip that provides a reliable and durable data storage solution for industrial and mission-critical applications. This innovative product combines 32k x 8 bits of static RAM with a self-contained lithium energy source and a control circuitry that constantly monitors 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.

Key Features:

• 10 years minimum data retention in the absence of external power
• Data is automatically protected during power loss
• Unlimited write cycles
• Read and write access times as fast as 200 ns
• Lithium energy source is internally isolated until power is removed
• Functionally equivalent to JEDEC standard 32k x 8 SRAMs
• Industrial temperature range (-40°C to +85°C)
• Directly replaces volatile static RAM or EEPROM
• Surface-mount package and drop-in replacement for battery-backed SRAM

Designed to be pin-compatible with standard SRAMs, the DS1230AB-200IND makes it easy to enhance system reliability without redesigning the memory subsystem. The industrial temperature range ensures that the device performs reliably in extreme environments, making it an ideal choice for industrial control systems, utility meters, medical equipment, and other applications where data integrity and retention are paramount.

With its unlimited write cycles, the DS1230AB-200IND outperforms traditional EEPROMs, which have limited endurance. The fast access time allows for high-speed data retrieval and storage, which is essential for real-time applications. The integrated lithium battery ensures that data is retained for a minimum of 10 years, providing peace of mind for long-term operation.

The robust design and construction of the DS1230AB-200IND make it a smart choice for designers looking for a nonvolatile memory solution that is both reliable and easy to integrate into their systems. Maxim Integrated's commitment to quality means that you can trust the DS1230AB-200IND to maintain the integrity of your valuable data over time.
