DS1258W-100# belongs to the category of Memory products. It is a CMOS based NonVolatile Static RAM (NVSRAM). NVSRAM provides an ideal data storage solution for microcontroller based system designs.

The DS1258W-100# has 128K x 8 bits of on-chip static RAM organized as sixteen one-kilobit segments. The bus and control lines are accessed by the two-pin MARC bus configuration. It includes logic to control the data flow to and from the external pins and features three nonvolatile write protection control lines to prevent accidental writes to the device.

The DS1258W-100# provides a fast-write, nonvolatile storage solution with write protection capability, data integrity, and power-fail protection. Its nonvolatile feature ensures that the memory contents are preserved during a power failure and upon system initialization, while its write protection features allow a write operation to be enabled, if necessary. The device is rated for operation from -40°C to +85°C. It is available in 44, 44-lead TQFP and 32, 32-lead PLCC packages.

The DS1258W-100# can be used for a wide range of applications including data acquisition systems, instrumentation systems, portable medical equipment, embedded control and wireless systems. In addition, its power down protection, fast write time and low power consumption makes it suitable for applications such as real-time clock, flash filesystem and general-purpose data storage.

The working principle of the DS1258W-100# is based on standard CMOS process technology, where two power features (Vcc and VPP) provide the necessary voltages for both data storage and control circuit operation. Additionally, each of the nonvolatile write protection control lines provides a third control feature, allowing users to select an appropriate level of write protection.

The two-pin MARC bus configuration allows easy interface with digital logic systems, while the nonvolatile feature and write protection capability provides the flexibility to store and protect digital information. The design has inherent ECC (Error Coding Capability) that provides data accuracy and integrity. The combination of excellent performance, cost-effectiveness and ease of use make the DS1258W-100# an ideal choice for many applications.
