Working Principles

The PC28F256P30BFE utilizes a parallel interface to communicate with the host device. It stores data in a non-volatile manner using floating-gate transistors. When data needs to be written, the appropriate voltage levels are applied to the specific address lines and data lines. The data is then stored in the memory cells by modifying the charge on the floating gates. During read operations, the stored data is retrieved by applying the appropriate address and reading the corresponding data lines.
