Memory: DS1249Y-85IND#

The DS1249Y-85IND# is a nonvolatile memory device manufactured by Dallas Semiconductor and operated over a wide temperature range. It is a 1Kb, 64-bit Nonvolatile Static RAM, or NVSRAM, packaged in a standard 8-pin dual-in-line (DIP) plastic package. The device comes in two size packages TSOP, and SOIC.

The DS1249Y-85IND#’s operating temperature range is from -40 to +85°C with power supply voltage ranging from 2.7V to 6.0V. The primary purpose of the 8-pin DIP memory device is to maintain data even when power is lost. The device provides reliable non-volatile data storage up to 100 years.

The DS1249Y-85IND# features multiple data and system protection features including ultra-low power consumption, deep power down mode, read and write endurance and a patented high-reliability NVSRAM algorithm specifically optimized for tight control over the retention mode. The read/write endurance is 10 million cycles, while the retention data is a minimum of 100 years at 25°C.

The DS1249Y-85IND# provides significant flexibility and superior protection for applications where unrestricted access to data maintained in nonvolatile memory is required. It is used in a wide range of applications including remote controls, on-board computers, motor protection devices, smart gas meters and security systems.

In terms of working principle, the DS1249Y-85IND# works by using an ultra-low power, NVSRAM circuit to quietly and consistently maintain data even in the absence of power. The device is composed of multiple cells divided into two parts. The first part is an array of 64-bit cells and the second part is a controlling circuit called data protection algorithm. This algorithm makes sure that all written data will remain unchanged even when power is lost.

The DS1249Y-85IND# Nonvolatile Static RAM device provides an economical and easy to integrate solution for applications requiring an ideal combination of speed, performance and protection in an NVSRAM device. It features fast, low-power operation and offers a reliable data storage over a wide temperature range.
