Working Principles

AT28HC64B-12JI utilizes EEPROM technology to store and retrieve digital information. It employs a combination of electronic circuits and memory cells to achieve non-volatile data storage. The memory cells consist of floating-gate transistors that can be electrically programmed and erased. When data is written to the memory, charges are trapped in the floating gate, altering the transistor's behavior and storing the information. The stored data can be read by applying appropriate voltage levels to the memory cells.

Detailed Application Field Plans

AT28HC64B-12JI finds applications in various electronic devices that require non-volatile memory storage, such as: - Microcontrollers - Embedded systems - Industrial control systems - Automotive electronics - Consumer electronics
