Maxim Integrated DS1245Y-85 Nonvolatile SRAM

The DS1245Y-85 is a high-quality, 1024k Nonvolatile SRAM product from Maxim Integrated that offers reliable data retention and easy integration into a wide range of applications. This memory device combines the access speed of static RAM with a nonvolatile storage component, ensuring that data is preserved even when the power is turned off.

Featuring a 32-pin EDIP (Encapsulated Dual In-line Package), the DS1245Y-85 operates on a 5V power supply and provides a fast access time of 85ns, making it an excellent choice for applications requiring rapid data access and storage without the need for a battery backup. The nonvolatile element is achieved through an internal lithium energy source and a control circuit that automatically transfers data to and from the nonvolatile memory cell during power transitions.

One of the key benefits of the DS1245Y-85 is its integrated partitioned 32k x8 SRAM and EEPROM, which allows for unlimited read and write cycles. The EEPROM portion is primarily used to store the data that must be retained upon power loss. In addition, the device comes with a JEDEC standard pinout, which is widely accepted and makes the design process more straightforward for engineers.

The DS1245Y-85 also features a write protect switch that provides hardware protection against inadvertent writes, thereby enhancing data integrity. The device is designed to withstand harsh conditions and is characterized for operation from -40°C to +85°C, making it suitable for industrial applications where temperature extremes are common.

With its robust design and reliable performance, the Maxim Integrated DS1245Y-85 is an ideal solution for a broad spectrum of applications, including but not limited to industrial control systems, medical equipment, data collection devices, and any other system requiring a dependable nonvolatile memory. Its ease of use, combined with the assurance of data preservation without external batteries, makes it a valuable component in the design of mission-critical systems.
