Working Principles

The DS1230WP-100+ utilizes a combination of CMOS (Complementary Metal-Oxide-Semiconductor) technology and non-volatile memory cells. When power is applied, the device operates as a standard static RAM, allowing for fast read and write operations. However, during power loss, an internal lithium energy source ensures that the data is retained in non-volatile memory cells.

Detailed Application Field Plans

The DS1230WP-100+ finds applications in various fields, including:

1. Industrial control systems: Used to store critical parameters and configurations in PLCs (Programmable Logic Controllers).
2. Medical devices: Ensures data integrity in medical equipment, such as patient monitoring systems.
3. Automotive electronics: Stores vital information in automotive control units, enabling reliable operation even during power interruptions.
4. Aerospace and defense: Utilized in avionics systems and military equipment to preserve critical data.
