Maxim Integrated DS1245AB-120+ Nonvolatile Memory

The DS1245AB-120+ is a high-performance, 1024k Nonvolatile (NV) SRAM with a built-in real-time clock from Maxim Integrated. This innovative memory solution offers a unique combination of volatile and nonvolatile memory, ensuring data preservation even when the power is lost, without the need for an external battery. The device is designed to deliver reliable data retention while providing the fast access times, low power consumption, and unlimited write cycles of a traditional SRAM.

With its access time of 120 ns, the DS1245AB-120+ provides the speed required for high-performance computing applications. The integration of the real-time clock (RTC) allows for time-stamping of data, which is essential for applications that require data logging or time-sensitive operations. The RTC is backed up by an internal lithium energy source that can maintain the clock operation for over 10 years in the absence of external power.

The DS1245AB-120+ features a 32-pin EDIP (Extended Dual In-line Package) and is compatible with JEDEC standard byte-wide SRAMs, making it easy to integrate into existing designs without the need for significant hardware modifications. The nonvolatile functionality is transparent to the user, as the device automatically transfers data to and from the nonvolatile cells at power-up and power-down, respectively.

This memory module is particularly suited for applications that require data integrity and reliability, such as industrial control systems, medical devices, and security systems. Its robust design ensures that data is not only secure during normal operation but also protected against data loss in unexpected power failure scenarios.

To facilitate easy implementation, Maxim Integrated provides comprehensive support, including detailed datasheets and technical support. The DS1245AB-120+ is a testament to Maxim Integrated's commitment to providing advanced memory solutions that meet the critical needs of today's sophisticated electronic systems.

For designers and engineers looking for a memory solution that combines the ease of use of SRAM with the nonvolatile data retention of EEPROM, the DS1245AB-120+ from Maxim Integrated is an excellent choice that offers reliability, durability, and the high level of performance expected from a leading semiconductor manufacturer.
