Working Principles

The 25AA320A-I/S16K utilizes a floating gate technology to store data in non-volatile memory cells. When data is written, charge is trapped in the floating gate, and this charge state determines the stored value. During read operations, the charge state is detected, allowing the retrieval of stored data.

Detailed Application Field Plans

• Automotive Electronics: Used for storing configuration data and event logs in automotive control units
• Consumer Electronics: Employed in smart home devices, wearables, and digital cameras for data storage
• Industrial Control Systems: Utilized for program storage in PLCs and industrial automation equipment
