Working Principles

N84C161WD28TG is based on Flash memory technology, which utilizes floating-gate transistors to store data. When a write operation is performed, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This change can be detected during subsequent read operations, allowing data retrieval. The chip's internal circuitry manages the addressing, reading, and writing processes.

Detailed Application Field Plans

• Embedded Systems: Used as non-volatile storage for firmware, configuration data, and program code in microcontrollers.
• Consumer Electronics: Employed in digital cameras, MP3 players, and other portable devices for data storage.
• Automotive Electronics: Utilized in car navigation systems, infotainment units, and engine control modules for reliable data storage.
• Industrial Automation: Integrated into PLCs (Programmable Logic Controllers) and industrial control systems for storing critical process data.
