Working Principles

The JS28F512P30EF0 utilizes a floating-gate transistor technology called NOR flash memory. It stores data by trapping electrons in the floating gate, which alters the transistor's threshold voltage. This allows the memory cell to retain its state even when power is removed. The data can be read by applying appropriate voltages to the address and control pins, while programming and erasing are achieved through specific voltage pulses.

The JS28F512P30EF0 is widely used in various electronic devices that require non-volatile data storage, such as:

1. Embedded systems
2. Consumer electronics (e.g., digital cameras, MP3 players)
3. Automotive applications (e.g., infotainment systems, engine control units)
4. Industrial equipment (e.g., PLCs, robotics)
5. Networking devices (e.g., routers, switches)
