Maxim Integrated DS1249Y-70IND# Nonvolatile RAM

The Maxim Integrated DS1249Y-70IND# is a high-performance, 2Mbit Nonvolatile (NV) SRAM with a built-in battery backup. This innovative memory solution is designed to retain data when the power supply is removed, making it an ideal choice for critical data storage applications where data persistence is of utmost importance.

The DS1249Y-70IND# operates with a supply voltage range of 4.5V to 5.5V and features an access time of 70ns, ensuring quick data retrieval and storage. This specific model is part of the industrial series, which means it has been designed to withstand harsher environmental conditions, with an operating temperature range of -40°C to +85°C.

One of the key attributes of this NV SRAM is its integrated lithium energy cell. This cell maintains the memory contents when the external power supply is compromised, thereby providing full operation for the life of the battery. The nonvolatility is ensured by an automatic power-fail chip deselect and write protection scheme that activates during power transitions.

This memory module comes in a 32-pin EDIP (Encapsulated Dual In-line Package) which makes it robust and suitable for various industrial applications. The DS1249Y-70IND# also includes a precision voltage monitor that automatically switches to the battery supply when a power failure occurs, safeguarding the integrity of the data stored within.

For ease of integration into existing systems, the DS1249Y-70IND# is designed to be pin-compatible with JEDEC standard 2Mbit SRAMs. This feature allows for a straightforward upgrade path for systems requiring nonvolatile memory solutions without extensive redesign.

In summary, the Maxim Integrated DS1249Y-70IND# Nonvolatile RAM is a reliable and durable memory component that offers both speed and security for your critical data storage needs. Its robust design, coupled with its nonvolatile feature, makes it an excellent choice for a wide range of industrial applications where data integrity cannot be compromised.
