Working Principles

The PC28F128M29EWLA utilizes a floating-gate transistor technology called NOR flash memory. It stores digital information by trapping electric charges within the floating gate, which alters the transistor's conductive properties. This allows the memory cell to retain its state even when power is removed.

During read operations, the stored charge is measured to determine the logic level of each memory cell. Write and erase operations involve applying specific voltage levels to modify the charge trapped in the floating gate.

Detailed Application Field Plans

The PC28F128M29EWLA is widely used in various electronic devices that require non-volatile data storage, such as:

1. Smartphones and tablets
2. Solid-state drives (SSDs)
3. Digital cameras
4. Automotive electronics
5. Industrial control systems
6. Embedded systems
