Maxim Integrated DS1220Y-120IND+ Nonvolatile SRAM

The Maxim Integrated DS1220Y-120IND+ is a robust, high-performance Nonvolatile SRAM designed to deliver reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by battery-backed SRAM. With a storage capacity of 16k, this device is perfect for applications that require fast access to data without the risk of data loss in case of power failure.

This particular model, the DS1220Y-120IND+, offers a 120 ns access time, making it a suitable choice for high-speed operations where quick data retrieval is crucial. It operates over an industrial temperature range, making it an ideal component for challenging environments where temperatures can range from -40°C to +85°C. This wide temperature range ensures that the device is reliable and maintains data integrity even in extreme conditions, making it perfect for industrial applications.

The DS1220Y-120IND+ integrates an automatic battery backup system that seamlessly switches to battery power when power failures are detected, ensuring that data is preserved. The nonvolatile control circuitry constantly monitors VCC for an out-of-tolerance condition. When such a condition occurs, the circuit write-protects the data, thus preventing data corruption during the power transition.

Featuring a 28-pin DIP (Dual In-line Package), this device is easy to integrate into existing systems. The pin compatibility with standard static RAM allows for a straightforward upgrade path for systems requiring nonvolatile memory solutions without the need for extensive redesigns.

Key features of the DS1220Y-120IND+ include:

• 16K Nonvolatile SRAM with full static operation
• No battery necessary for data retention
• Unlimited write cycles
• Read and write access times of 120 ns
• Automatic write-protection during power transitions
• 10 years of data retention in the absence of power
• Industrial temperature range of -40°C to +85°C

Overall, the DS1220Y-120IND+ from Maxim Integrated offers a reliable and durable nonvolatile memory solution that is well-suited for industrial applications where data integrity and operational reliability are paramount.
