Working Principles

The 71V67803S133BQG8 is a non-volatile Static Random Access Memory (nvSRAM) that combines the benefits of both SRAM and non-volatile memory technologies. It utilizes a ferroelectric material to store data, which retains its polarization state even when power is removed. This allows the IC to retain data without the need for a battery or external backup power source.

During normal operation, the IC functions like a standard SRAM, allowing for high-speed read and write operations. When power is lost, the ferroelectric material maintains the stored data, which can be accessed again once power is restored. This makes it suitable for applications where data integrity is critical, such as in industrial control systems, automotive electronics, and aerospace applications.

Detailed Application Field Plans

The 71V67803S133BQG8 IC finds application in various fields, including: 1. Industrial Control Systems: Used for storing critical system parameters and configuration data. 2. Automotive Electronics: Enables reliable storage of vehicle diagnostics, event logs, and firmware updates. 3. Aerospace Applications: Provides non-volatile memory for flight data recorders, avionics systems, and mission-critical data storage.
