DS1230W-150

Product Overview

Category

The DS1230W-150 belongs to the category of non-volatile static random-access memory (NVSRAM).

Use

It is primarily used for storing critical data in applications that require both high-speed read/write operations and non-volatility.

Characteristics

• Non-volatile: The DS1230W-150 retains data even when power is removed.
• High-speed operation: It offers fast read and write access times.
• Reliable: The NVSRAM technology ensures data integrity and endurance.
• Low power consumption: It operates at low power levels, making it suitable for battery-powered devices.
