Working Principles

The PC28F256P33TFA utilizes a parallel interface to communicate with the host device. It stores data in non-volatile memory cells, which retain information even when power is removed. The flash memory uses a combination of floating gate transistors and charge trapping techniques to store and retrieve data. When data needs to be written or erased, specific voltage levels are applied to the appropriate pins, modifying the charge state of the memory cells.
