Maxim Integrated DS1220AD-100IND+ Nonvolatile SRAM

The DS1220AD-100IND+ is a high-performance, 16k Nonvolatile SRAM designed by Maxim Integrated. This robust memory module provides a unique combination of volatile and nonvolatile memory functionality, ensuring data preservation even when the power supply is interrupted. It is an ideal solution for a wide range of industrial applications that require data integrity and reliability under harsh conditions.

This nonvolatile SRAM offers a storage capacity of 16 Kbytes, organized as 2K x 8 bits. It features access times as fast as 100 ns, making it suitable for high-speed microprocessor systems. The integration of an automatic internal battery and control circuitry ensures that data is retained for over 10 years in the absence of external power.

One of the key advantages of the DS1220AD-100IND+ is its ease of use, as it operates identically to a conventional static RAM when power is on. This allows for seamless integration into existing systems without the need for special software to manage nonvolatile functionality. In addition, the device's direct write protection feature safeguards against inadvertent data corruption.

The DS1220AD-100IND+ is designed to withstand industrial temperature ranges from -40°C to +85°C, making it suitable for use in environments that experience extreme temperatures. Its robustness is further enhanced by the inclusion of an industrial-grade enclosure, ensuring that the device can withstand the rigors of industrial operation.

For applications that demand long-term data retention without the need for an external battery, the DS1220AD-100IND+ is an excellent choice. It is commonly used in data logging, process control, instrumentation, and other critical systems where data must be preserved across power cycles.

Overall, the DS1220AD-100IND+ from Maxim Integrated is a reliable and durable memory solution that combines the best attributes of SRAMs and nonvolatile memory, making it a versatile component for industrial applications that cannot afford data loss.
