Working Principles
The AT28BV64-30JI utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It consists of a grid of memory cells, each capable of storing one bit of information. The device uses electrical signals to control the read, write, and erase operations on these memory cells.
During a read operation, the desired memory location is selected by providing the appropriate address inputs. The data stored at that location is then outputted through the data input/output pins.
For a write operation, the chip enable (CE), write enable (WE), and address inputs are used to select the target memory location. The data to be written is applied to the data input/output pins, and upon receiving the necessary control signals, the device stores the data in the specified location.
To erase data, the entire memory array or specific sectors can be erased using dedicated commands. This process involves applying specific voltage levels and timing sequences to ensure the removal of previously stored data.
