Working Principles

The BR93L76RFVJ-WE2 utilizes a floating gate transistor structure to store data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge remains even when power is removed, allowing the device to retain the stored information. During read operations, the transistor's behavior is determined by the presence or absence of the trapped charge, enabling data retrieval.

Detailed Application Field Plans

The BR93L76RFVJ-WE2 is commonly used in various electronic devices that require non-volatile memory storage, such as: - Smart meters - Industrial control systems - Automotive electronics - Consumer electronics (e.g., digital cameras, set-top boxes)
