Working Principles

AT28HC64B-12TI utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. The memory cells are organized into an 8K x 8-bit array, with each cell capable of storing one byte of data. The chip's control pins enable various operations such as reading, writing, and erasing data. The memory can be accessed using the address inputs to specify the desired location, and the data inputs/outputs facilitate data transfer between the chip and the external system.

Detailed Application Field Plans

AT28HC64B-12TI finds applications in a wide range of electronic devices and systems, including but not limited to: - Embedded systems - Microcontrollers - Industrial control systems - Automotive electronics - Communication equipment - Consumer electronics
