Maxim Integrated DS1230Y-X15 Nonvolatile SRAM

The DS1230Y-X15 is a high-quality, nonvolatile SRAM product from Maxim Integrated, designed to provide reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by battery-backed SRAM. With a storage capacity of 256k, this memory module is an ideal solution for a wide range of applications that require the preservation of data in the event of a power failure.

This innovative memory module integrates 32k x 8 nonvolatile static RAM, a precision voltage monitor, and an automatic lithium battery controller into a single 28-pin, 600 mil DIP package. The unique feature of the DS1230Y-X15 is its ability to retain data upon power loss without the need for an external battery. The internal 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 writes protection is unconditionally enabled to prevent data corruption.

DS1230Y-X15 offers a fast access time of 150 ns, making it suitable for high-speed microprocessor systems. In addition, its infinite read and write endurance ensures that the memory can be accessed repeatedly without degradation of the memory cells. The module's data retention is rated at over 10 years, providing long-term reliability for critical data storage.

The device operates over a wide temperature range, making it suitable for demanding industrial applications. The nonvolatile functionality of the DS1230Y-X15 is transparent to the user, requiring no additional support or handling, which simplifies system design and enhances overall system reliability.

Overall, the Maxim Integrated DS1230Y-X15 Nonvolatile SRAM is a robust, high-performance solution that offers the benefits of nonvolatile memory with the speed and ease of use of SRAM, making it an excellent choice for a variety of data storage and preservation applications.
