Working Principles

JR28F032M29EWHA utilizes floating-gate transistors to store digital information. When data is written, electrons are trapped in the floating gate, altering the transistor's threshold voltage. This change determines whether the transistor represents a "0" or "1" bit. During read operations, the threshold voltage is measured to retrieve the stored data.

Detailed Application Field Plans

• Embedded systems: Used in microcontrollers, IoT devices, and automotive electronics for program storage.
• Consumer electronics: Found in smartphones, tablets, and digital cameras for data storage.
• Industrial automation: Utilized in control systems and PLCs for program storage and data logging.
• Networking equipment: Employed in routers, switches, and network appliances for firmware storage.
