Maxim Integrated DS1235YW Nonvolatile SRAM

The Maxim Integrated DS1235YW is a high-performance, 256k Nonvolatile SRAM designed to provide a reliable and durable memory solution for applications requiring data preservation across power cycles. With its unique blend of volatile and nonvolatile memory benefits, the DS1235YW offers fast access times and infinite read/write endurance of a standard SRAM, coupled with a nonvolatile data retention capability typically associated with ROM or EEPROM technologies.

This innovative memory module integrates a quantity of 32,768 words by 8 bits, amounting to a total of 256 kilobytes of storage capacity. The DS1235YW is distinguished by its ability to automatically save the SRAM data to nonvolatile memory when power loss is detected and restore it upon power return, ensuring data integrity without the need for an external battery.

Key features of the DS1235YW include:

• Power-fail protection: The device includes an automatic power-fail chip deselect and write protection, securing data during power loss.
• Access time: It boasts fast read and write access times, significantly improving system performance for memory-intensive operations.
• Reliability: The DS1235YW offers a high level of data reliability with its nonvolatile storage capability, ensuring data is preserved for over 10 years.
• Easy integration: It is designed to be pin-compatible with JEDEC standard 28-pin 256kx8 SRAMs, allowing for straightforward integration into existing designs without extensive redesign.
• Temperature range: This product is available in the industrial temperature range, denoted by the 'YW' suffix, making it suitable for harsh environments.

Applications for the Maxim Integrated DS1235YW are diverse and include industrial control systems, data collection devices, medical equipment, and any other system where data integrity and retention are critical. With its robust design and reliable nonvolatile memory technology, the DS1235YW stands out as an excellent choice for designers looking to enhance their systems with secure and persistent memory storage.
