• High endurance: Can withstand a large number of write/erase cycles.
• Fast access time: Provides quick access to stored data.
• Flexible programming options: Supports byte-wise programming and automatic page write.

Disadvantages

• Limited storage capacity: The AT28C64E-15JC has a relatively small storage capacity compared to other memory devices.
• Higher cost: EEPROM chips are generally more expensive than other types of memory.

Working Principles

The AT28C64E-15JC utilizes a floating-gate transistor structure to store data. When a byte is programmed, charge is trapped in the floating gate, representing a logical "1." Erasing the byte removes the charge, resulting in a logical "0." The state of each memory cell is determined by the presence or absence of charge in its floating gate.

Detailed Application Field Plans

The AT28C64E-15JC finds applications in various electronic systems, including but not limited to: - Embedded systems - Automotive electronics - Industrial control systems - Consumer electronics - Communication devices
